また、隠蔽層６の直径（ｘ）が接着テープの幅（ｙ）と同じ場合（すなわちｘ＝ｙの場合）には、数３の長さの接着テープが隠蔽層の外周よりも出てしまうため、ニス層５は、少なくとも直径を数４にして隠蔽層６よりも面積を大きくし、かつ、数１の長さが隠蔽層６の外周よりも出るように設ける必要がある。

また、隠蔽層６の直径（ｘ）が接着テープの幅（ｙ）よりも小さい場合（すなわちｘ＜ｙの場合）には、数５の長さの接着テープが隠蔽層６の外周よりも出てしまうため、ニス層５は、少なくとも直径を式６にして隠蔽層６よりも面積を大きくし、かつ、数１の長さが隠蔽層６の外周よりも出るように設ける必要がある。

これらはニス層５が隠蔽層６よりも出る最小の寸法であり、この寸法で隠蔽層６よりも出るようにニス層５を設けるとニス層５の原材料を最小にすることができ、製造コストを抑えることができる。しかし、これに限定するものではない。また、本実施の形態ではニス層５と隠蔽層６を共に円としているが、これに限定する必要は無く、隠蔽層６を剥がす際に接着テープが基板シート２に貼着することを防ぐことができれば、どのような形にしてもよい。
【００９１】
また、くじ部分は、６個のうち1つだけが「あたり」であり、残りは「はずれ」になるように設定されている。「あたり」という情報を有しているあたりくじ部分でも「はずれ」という情報を有しているはずれくじ部分でも外観は同じである。よって、通常の状態では、どのくじ部分が「あたり」で、どのくじ部分が「はずれ」であるのかを判断することはできない。抽選カードを使用する者は、６つのくじ部分の中から一つを選択して、接着テープによって選択したくじ部分の隠蔽層を剥がして、初めて、自分の選択したくじ部分が「あたり」なのか「はずれ」なのかを知ることができる。本実施の形態では、抽選情報を「あたり」なら『当選』、「はずれ」なら『落選』という情報を提供するものとしたがこれに限定する必要はない。抽選情報は『当選』、『落選』という情報以外でもよく、例えば、ビンゴゲームの番号でもよいし、更には、児童の学習用の『解答』に該当する情報を提供するものなどでもよい。
【００９２】
抽選カード１を製造するには、まず基材シート２上に、情報インキ層と重複しない位置に絵柄部分である見だし部８と絵柄部分である注意書き部９をグラビア印刷方式によって塗布し、次に、基板シート上に情報インキ層をグラビア印刷方式によって塗布し、次に、情報インキ層を覆うように、かつ、まだ何も印刷されていない基板シート上にもかかるようにニス層をグラビア印刷方式で塗布し、次に、隠蔽層をグラビア印刷方式で塗布している。
【００９３】
各層の形成方法について更に詳しく説明する。情報インキ層は、ロジン系樹脂のインキを用いて設けられている。本実施の形態では、ロジン系樹脂のインキを用いたが別段これに限定する必要は無く、通常のグラビア印刷で用いられるインキを使用することができる。また、その網点面積率が略３０％になるように設けられている。情報インキ層の網点面積率が略３０％以下になるように設けることによって、基板シートの裏面から強い光を当てて抽選情報を不正に読み取ることを防ぐ事ができる。すなわち、出願人の実験によれば、網点面積率を１０％にして情報インキ層を設けた場合は、裏面から強い光を当てても隠蔽層に抽選情報が影として写らないが、隠蔽層を剥がしたときに、抽選情報が薄いため、凝視しなければ抽選情報を読み取ることができないという状態であり、網点面積率を２０％、３０％にして設けた場合では、裏面から強い光を当てても隠蔽層に抽選情報が影として写らなく、隠蔽層を剥がしたときも、抽選情報を容易に読み取れることができ好ましい状態であり、網点面積率を４０％にして設けた場合では、裏面から強い光を当てると抽選情報が影として写ってしまう、という結果を得た。したがって、更に好ましくは、網点面積率を２０％〜３０％にして設けるのが好ましい。
【００９４】
ニス層は塩化ゴム系樹脂のニスインキを用いて設けられており、隠蔽層はニトロセルロース系樹脂の銀インキを用いている。ニス層と隠蔽層は、接着テープによって隠蔽層を剥がす際に、ニス層と隠蔽層の間で剥がれるようにするために、夫々の層を形成する樹脂が、相反性を有する樹脂を選択する必要がある。本実施の形態では、ニス層に用いる塩化ゴム系樹脂と、隠蔽層に用いるニトロセルロース系樹脂には相反性があり、隠蔽層はニス層に対して低密着性、低接着性、を示しているので、隠蔽層の上に接着テープを貼着し引き剥がすことで、隠蔽層とニス層の間で剥離して、隠蔽層のみを剥がすことができる。ニス層には、塩化ゴム系樹脂の他に、塩化ビニル一酢酸ビニル共重合体樹脂等を使用することができる。隠蔽層には、ニトロセルロース系樹脂の他に、ポリアミド系樹脂、アクリル系樹脂等を使用することができる。本実施の形態では、ニス層は透明であるが、情報インキ層が目視できれば、半透明でもよいし、色材を混入して着色してもよい。ただし、着色する際には、情報インキ層が目視できるようにするのはもちろんのこと、隠蔽層と十分な相反性を有するように注意が必要である。本実施の形態では、隠蔽層はニトロセルロース系樹脂の銀インキであるが、別段これに限定する必要は無く、情報インキ層を隠蔽することができれば藍インキや墨インキを採用してもよい。銀インキ以外の色を採用する際は、情報インキ層よりも濃度が濃くなるように設けた方が、情報インキ層をより隠蔽することができるので好ましい。
【００９５】
なお、くじ部分以外に、情報インキ層と貼着しなければ絵柄部分も設けることも可能である。本実施の形態ではくじ部分以外には絵柄部分である見だし部８と絵柄部分である注意書き部９しか設けていないが、情報インキ層と重複しなければこれら以外にも絵柄部分として文字、記号、図形若しくはこれらの結合を設けてもよい。本実施の形態では、絵柄部分を設けてから、くじ部分を設けるという順序を採用しているが、くじ部分を設けてから絵柄部分を設けるという順序を採用することも可能である。本実施の形態において、まず絵柄部分を設けた後、くじ部分を順に積層してゆくという方法を採用している理由は、隠蔽層に傷がつくことを防ぐためである。くじ部分を設けてから絵柄部分を設けるという後述した方法を採用することも可能であるが、後述した方法を採用すると、製造過程において隠蔽層を塗布してから、絵柄部分を塗布するために再び印刷機にかけることになり、その結果、すでに設けた隠蔽層の上をローラーが通ることになるので隠蔽層に傷がついてしまうという可能性が生じてくる。隠蔽層に傷がついてしまうと、美観を損ねるだけでなく、傷の隙間から隠蔽してある抽選情報が目視可能になりかねない。本願発明の隠蔽層は接着テープを用いなければ剥がすことができず、隠蔽層はとても強固なものであるので、後者の方法を採用したことにより、隠蔽層に傷がついてしまうことは発生し難いがあまり好ましい方法ではない。しかし、現実的には選択可能な生産方法であり、本願発明においても一応採用することは可能である。別段、これらの順序に限定する必要はなく、例えば、情報インキ層を設ける工程の後に絵柄部分を設ける工程にし、その後にニス層を設ける工程にしても良く、順序は自由に選択可能である。
【００９６】
本実施の形態では、印刷手法としてはオフセット印刷を採用しているがこれに限定するものではなく、塗布可能であれば他の手段でもよい。例えば、オフセット、シルクスクリーン等他の印刷方式を採用してもよく、印刷方法以外の方法としてローラー部分塗布、刷毛塗り等を採用してもよい。また、本実施の形態では、全ての層をグラビア印刷方式で形成しているが、これに限定する必要は無い。各層を設けるために採用する手段は、塗布可能であればどのような方法を採用してもよい。例えば、隠蔽層を設けるためにシルクスクリーン印刷方式を採用すれば、隠蔽層を厚くすることができるので、隠蔽作用を向上させることができるし、情報インキ層を設けるためにグラビア印刷方式を採用すれば隠蔽層にできる情報インキ層の凹凸を目立たなくすることが可能となる。しかし、それぞれの層を形成するために様々な印刷方法を混用すると工程が複雑になり、製造コストが上がってしまうので、注意が必要である。なお、本願発明では、本実施の形態のように全ての層をある一つの印刷方式で一貫して形成することが可能であるので、製造コストを最小限に抑えることができる。グラビア印刷方式を採用して一貫して形成する場合は前述した通りである。オフセット印刷方式を採用して一貫して形成する場合について説明する。オフセット印刷方式の場合は、ニス層に通常のオフセット印刷で使用するニスを使用し、ニス層以外の層（情報インキ層、隠蔽層）に紫外線硬化型インキを使用することによって、ニス層と隠蔽層の間に相反性を持たせることが可能となる。オフセット印刷方式を採用して、一貫して作成する方法は、本願出願人より、特許番号第２７１１７７２号において開示されている。スクリーン印刷方式を採用した場合はグラビア印刷方式を採用した場合と同様であるため説明を割愛する。
【００９７】
基板シートの材料としては、例えば、一般的にアート紙、コート紙、上質紙、中質紙、アートポスト紙、マットコート紙、軽量コート紙、純白ロール紙、微塗工紙として微塗工上質紙、微塗工印印刷紙１、微塗工印刷紙２、微塗工印刷紙３、版紙としてコートボール、ノーコートボール、アイボリー、両面カード等の印刷に用いられる紙でもよいし、包装用のクラフト紙袋に使用されるクラフト紙等、いずれの紙を基板シートに採用することができる。また、夫々の坪量は、いずれのものを採用することもできる。
【００９８】
次に図２を参照してニス層の様式の一例について説明する。なお、図２において、隠蔽層２４を透明にして隠蔽している情報インキ層１７を見える状態にしているが、これは図を見やすくするためであり、実際には、情報インキ層１７は隠蔽層２４によって隠蔽されているので通常の状態では見ることはできない。
【００９９】
図２は別の実施の形態を示すくじ部分の上面図である。図２において１６はくじ部分、１７は情報インキ層、１８はニス層、１９はニス層１８のうち隠蔽層２４と重複している重複部分、２０はニス層１８のうち隠蔽層２４の外周の右側から出ているニス層右突出部分、２１はニス層１８のうち隠蔽層２４の外周の左側から出ているニス層左突出部分、２２はニス層の短軸、２３はニス層の長軸、２４は隠蔽層、２５は隠蔽層２４のうちニス層１８と重複している重複部分、２６は隠蔽層２４のうちニス層１８の外周の上側から出ている隠蔽層上突出部分、２７は隠蔽層２４のうちニス層１８の外周の下側から出ている隠蔽層下突出部分、２８は隠蔽層の直径、２９は隠蔽層２４の中心、３０は隠蔽層接線、３１は隠蔽層２４の外周とニス層１８の長軸とが交わる点である。
【０１００】
図２において、くじ部分１６は図示しない基板シート上に設けられており、情報インキ層１７とニス層１８と隠蔽層２４よりなる。ニス層１８は楕円の形をしており、隠蔽層２４と重複する重複部分１９と、この重複部分１９の左右に連接するニス層右突出部分２０とニス層左突出部分２１を有している。隠蔽層２４は円の形をしており、ニス層１８と重複する重複部分２５と、この重複部分２５の上下に連接する隠蔽層上突出部分２６と隠蔽層下突出部分２７を有している。ニス層１８は、長軸２３が隠蔽層の直径２８よりも長く、短軸２２が隠蔽層の直径２８よりも短く、かつ、その面積が隠蔽層２４よりも大きくなるように設定されている。また、ニス層１８の短軸２２と長軸２３の交点が隠蔽層２４の中心２９に重なるように設けられている。すなわち、図２は、ニス層１８を、隠蔽層２４よりも面積が大きく、かつ、隠蔽層２４の外周の一部から出るように設け、更に、隠蔽層２４を、ニス層１８よりも面積が小さく、かつ、ニス層１８の外周の一部から出るように設けた事を特徴とする印刷物のくじ部分を示す上面図である。更に詳しく説明すれば、ニス層１８は、隠蔽層２４よりも面積が大きく、かつ、隠蔽層２４の外周の左側と右側から出るように設けられている。また、隠蔽層２４は、ニス層１８の上に位置し、ニス層１８よりも面積が小さく、かつ、ニス層１８の外周の上側と下側から出るように設けられている。ここで、ニス層１８のうち隠蔽層２４と重複する重複部分１９と、隠蔽層２４のうちニス層１８と重複する重複部分２５は上下に重なっており、情報インキ層１７は、この重複部分の範囲に納まるように、図示しない基板シート上に設けられている。
【０１０１】
図２を更に詳しく説明する。図２において、ニス層１８と隠蔽層２４の一部分はそれぞれが上下に重複していない。隠蔽層２４の外周の右側から出ているニス層右突出部分２０と、隠蔽層２４の外周の左側から出ているニス層左突出部分２１の上には隠蔽層２４が積層されていない。また、隠蔽層２４のうち、ニス層１８の外周の上側から出ている隠蔽層上突出部分２６と、ニス層１８の下側から出ている隠蔽層下突出部分２７は、それぞれの部分の下にニス層１８が存在せず、基板シートの上に直接積層されている。隠蔽層接線３０は、隠蔽層２４の外周とニス層１８の長軸とが交わる点３１において隠蔽層２４と接するように引いた接線がニス層１８の外周と交わる点で切ったものである。隠蔽層２４のうちニス層１８と重複する部分２５を剥離するために用いる接着テープは、その幅がこの隠蔽層接線３０の長さ以下のものでなければ、重複部分２５を剥がす際に基板シートに接着テープが貼着してしまうので使用することができない。家庭用の接着テープの幅は１２ｍｍもしくは１５ｍｍが多く見うけられる。したがって、隠蔽層接線３０の長さが１２ｍｍ以上になるように、更に、隠蔽層２４よりも面積が大きく、かつ、隠蔽層２４の外周よりも出るようにニス層１８の短軸２２と長軸２３を設定することが好ましい。また、ニス層１８と隠蔽層２４との重複部分２５を０．３５ｍｍ以上の大きさの文字が2文字以上設けることができる大きさに設定することが望ましい。ニス層１８と隠蔽層２４との重複部分２５を剥がす際には、ニス層右突出部分２０又はニス層左突出部分２１のどちらか好きな方に、接着テープの先端を隠蔽層接線３０の近辺に合わせて貼り、ニス層１８と隠蔽層２４の重複部分を覆って、反対側のニス層突出部分にある隠蔽層接線３０の近辺まで貼った後、引き剥がすことで、紙剥けを生じることなくニス層１８と隠蔽層４との重複部分２５を剥がすことができる。
【０１０２】
ニス層１８と隠蔽層２４との重複部分２５を剥がす際に、隠蔽層上突出部分２６と隠蔽層下突出部分２７は、その下にニス層１８が存在せずに基板シート上に直接積層されている。したがって、隠蔽層上突出部分２６と隠蔽層下突出部分２７は、隠蔽層２４を形成しているインキが基板シートに染み込んでいるため、剥がすことができない。もし、隠蔽層上突出部分２６と隠蔽層下突出部分２７を無理に剥がそうとするならば、紙ごと剥くことになってしまう。このことによって一度剥がしたものを元通りにすることを困難にすることができる。すなわち、1枚のくじカードにいくつものくじ部分があり、接着テープによってそのうちの1つのくじ部分を選択して、隠蔽層を剥がしたとき、それが、「はずれ」だった場合、何らかの手段を用いて剥がした隠蔽層を元に戻し、あたかも「あたり」の部分のみを剥がしたかのように見せかけるという不正を防止することが可能となる。ここで元に戻すための手段としては、剥がした隠蔽層をもう一度貼りつける方法や、隠蔽層を全て剥がし、もう一度隠蔽層を印刷方法やその他の手段によって新たに隠蔽層を設ける方法など様々な方法がある。
【０１０３】
本実施の形態の隠蔽層２４を接着テープによって剥がすと、隠蔽層２４のうち、隠蔽層上突出部分２６と隠蔽層下突出部分２７が基板シートに残るため、元に戻そうとすると、基板シートに残った上下の隠蔽層突出部分と継ぎ目が無い様に戻さなくてはならなくなる。もともとの隠蔽層２４は表面が平滑であるので、基板シートに残った上下の隠蔽層突出部分と平滑になるように元に戻さなければ、一目見てすぐに不正な行為をしたことが見破られてしまう。更に、基板シートに残った上下の隠蔽層突出部分も剥がした後に隠蔽層を設けようとしても、残った上下の隠蔽層突出部分は隠蔽層を形成するインキが基板シートと強力に結びついているため、無理やり剥がそうとすると、紙ごと剥いてしまい、紙を剥いてしまった部分まで元に戻し、その後に隠蔽層を新たに設けるのは非常に困難である。くじ部分をいくつも設けたくじにおいて、接着テープによって剥がしたものが「はずれ」であった場合に、剥がしてしまった隠蔽層をあたかも剥がしていないかのように元に戻し、「あたり」が出るまでいくつものくじ部分を剥がしてゆくという不正行為はかなり多く発生し、従来から様々な対策技術がある。本願発明では基板シートに薄い紙を採用できるだけでなく、かつ、このような不正行為をも防止することができる。
【０１０４】
隠蔽層上突出部分２６と隠蔽層下突出部分２７の大きさは問わないが、剥離するニス層１８と隠蔽層２４との重複部分２５が大きく、かつ、基板シートに残る隠蔽層上突出部分２６と隠蔽層下突出部分２７が大きいほど元に戻すことを困難にすることができると予想される。ただし、隠蔽層２４からニス層１８の一部が出ていても、隠蔽層２４の面積がニス層１８よりも大きくなってしまうと、誤って、ニス層１８が設けられれていない部分に接着テープを貼着してしまう可能性が高くなるため、ニス層１８の面積は隠蔽層２４よりも大きくすること必要がある。
【０１０５】
更に図３を参照して図２を応用した例について説明する。なお、図３において、隠蔽層５６を透明にして隠蔽している情報インキ層４１を見える状態にしているが、これは図を見やすくするためであり、実際には、情報インキ層４１は隠蔽層５６によって隠蔽されているので通常の状態では見ることはできない。
【０１０６】
図３は別の実施の形態を示すくじ部分の上面図である。図３において、４０はくじ部分、４１は情報インキ層、４２はニス層、４３はニス層４２のうちの左片部分、４４はニス層４２のうちの右片部分、４５は左片部分４３の右辺、４６は右片部分４４の左辺、４７は右片部分４４の右辺、４８は右片部分４４の上辺、４９は右片部分４４の下辺、５０は連接部分の中点、５１は左辺部分である矢印部分の横軸、５２は左辺部分である矢印部分の縦軸、５３はニス層４２のうち隠蔽層５６と重複している重複部分、５４はニス層４２のうち隠蔽層５６の外周の右側から出ているニス層右突出部分、５５はニス層４２のうち隠蔽層５６の外周の左側から出ているニス層左突出部分、５６は隠蔽層、５７は隠蔽層５６のうちニス層４２と重複している重複部分、５８は隠蔽層５６のうちニス層４２の外周の左上側から出ている隠蔽層左上突出部分、５９は隠蔽層５６のニス層４２の外周の左下側から出ている隠蔽層左下突出部分、６０は隠蔽層５６の中心、６１は左隠蔽層接線、６２は注意書き、６３は右貼着個所指示線、６４は左貼着個所指示線である。
【０１０７】
図３において、くじ部分４０は図示しない基板シート上に設けられており、情報インキ層４１、ニス層４２、隠蔽層５５よりなる。情報インキ層４１は抽選情報を形成している層であり、本実施の形態では「あたり」を形成している。ニス層４２は、左片部分４３と右片形部分４４からなり、左片部分４３と右片部分４４は、必ず連接しているものである。本実施の形態では、左片部分４３は右片部分４４とは対称の方向を向いた矢印の形をしており、右片部分４４は長方形の形をしている。そして、左片部分４３の右辺４５と、右片部分４４の左辺４６によって左辺部分と右辺部分は連接されている。また、連接するそれぞれの片の中点が合わさるように連接されている。隠蔽層５６は円であり、隠蔽層５６の中心６０が、ニス層４２の左片部分４３の右辺４５とニス層４２の右片部分４４の左辺４６との連接部分の中点５０、と略同じ位置になるように設けられ、隠蔽層５６とニス層４２は上下に積層されている。ニス層４２は、左片部分４３と右片部分４４とを連接した状態で、隠蔽層５６よりも面積が大きく、かつ、ニス層４２の一部分が隠蔽層５６の外周から出るように設計されている。更に、隠蔽層５６はニス層４２よりも面積が小さく、かつ、隠蔽層５６の一部分がニス層４２の外周よりも出るように設けられている。すなわち、ニス層４２のうち右辺部分４４は、右片部分４４の左辺４６と右片部分４４の右辺４７が隠蔽層５６の直径の長さ以上になるように、かつ、右片部分４４の上辺４８と右片部分４４の下辺４９が隠蔽層５６の半径の長さ以上になるように設計されており、また、ニス層４２のうち左辺部分４３は、矢印の頂点から連接部分の中点までを横軸５１、横軸５１に垂直で矢印の軸部分を縦軸５２とすると、縦軸５２の長さが隠蔽層５６の直径よりも短くなるように、かつ、横軸５１の長さが隠蔽層５６の半径よりも長くなるように設けられている。したがって、正面から見た場合、隠蔽層５６の中心６０に近い部分より右側の半円の外周からはニス層右突出部分５４が不均一に出ており、隠蔽層５６の中心６０に近い部分より左側の半円の外周の一部分からはニス層左突出部分５５が不均一に出ている。よって、これらの左右の突出部分５４、５５が隠蔽層５６よりも出ているため、ここを利用することにより隠蔽層５６のうちニス層４２と重複する重複部分５７を剥離する際に接着テープが基板シートに貼着することを防ぐ事ができる。また、正面から見た場合、隠蔽層５６のうちニス層４２と重複している重複部分５７から左上に突出している隠蔽層左上突出部分５８と、重複部分５７から左下に突出している隠蔽層左下突出部分５９がニス層４２から出ており、基板シート上に直接積層されている。よって、隠蔽層５６のうちニス層４２と重複する重複部分５７を剥がした後は隠蔽層５６の一部分である左側上下の突出部分５８、５９が残るため、これらの部分で一度剥がしたものを元に戻すという不正行為を防ぐ事が可能となる。ここで、ニス層４２のうち隠蔽層５６と重複する重複部分５３と、隠蔽層５６のうちニス層４２と重複する重複部分５７は上下に重なっており、情報インキ層４１は、この重複部分の範囲内の図示しない基板シート上に設けられている。
【０１０８】
なお、ニス層４２と隠蔽層とが重複している重複部分５２、５７は、０．３５ｍｍ以上の大きさの文字が2文字以上設けることができる大きさに設計することが好ましいのはいうまでもない。更に、剥がすために用いる接着テープの幅が隠蔽層接線６１の長さ以下になるようにニス層４２と隠蔽層５６を設計することが好ましい。また、隠蔽層５６からニス層４２の一部が出ていても、隠蔽層５６の面積がニス層４２よりも大きくなってしまうと、誤って、ニス層４２が設けられれていない部分に接着テープを貼着してしまう可能性が高くなるため、ニス層４２の面積は隠蔽層５６よりも大きくする必要がある。
【０１０９】
また、ニス層のうち右片部分４４に注意書き６２を設けているが、この注意書き６２は設けても設けなくてもよい。設けた方が、誤ってニス層４２を隠蔽層５７よりも出るように設けていない個所に接着テープを貼着してしまうことを防ぐ事ができるので、設けた方が好ましい。図３のように、右貼着個所指示線６３と左貼着個所指示線６４によって接着テープを貼着する範囲を明確に示すことによって、使用者は左貼着個所指示線６４の近辺に接着テープを貼着し始め、隠蔽層５６のうちニス層４２と重複する重複部分５７の一部を覆い、右貼着個所指示線６３の近辺にまで張ったのち、矢印の方向に剥がすようになり、誤ってニス層４２が設けられていない部分に接着テープを貼着する可能性を低くすることができる。なお、左貼着個所指示線６４の近辺に接着テープを貼着し始め、隠蔽層５６のうちニス層４２と重複する重複部分５７の一部を覆い、右貼着個所指示線６３の近辺にまで張った後、矢印の方向に剥がすという剥がし方は、右利きの人を想定した場合であり、左利きの人はこの逆になると考えられる。
【０１１０】
注意書き６２の設け方は、図３では、情報インキ層４１を設けるのと同時に設けているが、別段これに限定する必要は無い。どこの工程で設けてもよいし、設ける手段は塗布できればどのような方法を用いてもよい。また、本実施の形態では、ニス層４２のうち左片部分４３を矢印の形に、右片部分４４を長方形にしたが、別段これに限定する必要は無い。ニス層４２の面積が隠蔽層５６よりも大きく、更に、隠蔽層５６をニス層４２の上に設けた場合に、隠蔽層５６の外周の一部からニス層４２の一部が出て、かつ、ニス層４２の外周の一部から隠蔽層５６の一部が出ていればどのように設けてもよい。
【０１１１】
次に、図４を参照して、ニス層の様式の一例について説明する。なお、図４において、隠蔽層７３を透明にして隠蔽している情報インキ層７１を見える状態にしているが、これは図を見やすくするためであり、実際には、情報インキ層７１は隠蔽層７３によって隠蔽されているので通常の状態では見ることはできない。
【０１１２】
図４（A）は別の実施の形態を示すくじ部分の上面図である。図４（A）において、７０はくじ部分、７１は情報インキ層、７２はニス層、７３は隠蔽層、７４はニス層の中心、７５は隠蔽層の中心、７６はニス層の直径、７７は隠蔽層の直径、７８は剥離可能限界線、７９は隠蔽層のうち剥離可能限界線によって分けられる剥離部分、８０は隠蔽層のうち剥離可能限界線によって分けられる残存部分、８１はニス層余白部分である。
【０１１３】
図４（A）において、くじ部分７０は図示しない基板シート上に設けられており、情報インキ層７１、ニス層７２、隠蔽層７３よりなる。ニス層７２と隠蔽層７３は共に円の形をしており、ニス層７２の直径７４が隠蔽層７３の直径７６よりも長くなるように設計されている。また、隠蔽層７３は、ニス層７２の上に積層されており、隠蔽層７３は、その全体がニス層７２よりも出ない程度に、ニス層の中心７４よりも右下にずらして設けられている。すなわち、ニス層７２が隠蔽層７３よりも面積が大きく、かつ、隠蔽層７３よりも不均一に出るように設けられている状態である。ニス層余白部分８１は、隠蔽層７３をニス層７２よりも右下にずらしたことによりできる、ニス層７２が隠蔽層７３よりも出ている最大の場所であり、ここを利用することによって隠蔽層７３を剥がすときに基板シートに接着テープが貼着することを防ぐことができる。
【０１１４】
剥離可能限界線７８は、接着テープの幅が、ニス層７２の弧の長さと一致する場所を指示する線分である。接着テープによって隠蔽層７３を剥がす際は、隠蔽層７３全てを剥がすことができない。隠蔽層７３のうち剥離可能限界線７８によって分けられる残存部分８０側は剥がすことができずに残る。なぜなら、隠蔽層７３を、ニス層７２よりも出ないようにその中心を右下にずらしたため、隠蔽層７３のうち剥離可能限界線７８によってわけられる残存部分８０側は、接着テープが基板シートに貼着することを防ぐ事ができる程度までニス層７２が出ていないからである。よって、隠蔽層７３全体を覆うように接着テープを貼着すると、隠蔽層７３のうち剥離可能限界線７８によって分けられる残存部分８０側で接着テープが基板シートに貼着してしまう。したがって、剥離可能限界線７８で分けられる剥離部分７９が剥離できる最大範囲となり、情報インキ層７１は、隠蔽層７３のうち、この剥離可能限界線７８で分けられる剥離部分７９側に設けられている。
【０１１５】
また、例えば、隠蔽層７３をニス層７２の外周に重なるようにずらしたり、ニス層７２の外周から隠蔽層７３の一部が出てしまうまでずらすことも可能である。しかし、隠蔽層７３をニス層７２の外周に重なるようにずらすと、隠蔽層７３の大きさによっては、隠蔽層７３のうち剥離可能限界線７８によって分けられる剥離部分７９がかなり小さくなってしまうことも考えられるため、好ましくはない。また、ニス層７２の外周から隠蔽層７３の一部が出てしまうほどずらしてしまうと、ニス層７２の輪郭が隠蔽７３層によってわからなくなってしまい、隠蔽層７３を剥がす際に誤ってニス層７２が設けられていない部分にまで接着テープを貼着してしまう恐れが生じるので、「これ以上は貼着しないでください」などの注意書きを設けるとよい。
【０１１６】
図４（B）は別の実施の形態を示すくじ部分の上面図である。図４（B）において、８５はくじ部分、８６は情報インキ層、８７はニス層、８８は隠蔽層、８９はニス層の高さ、９０は隠蔽層の直径、９１は剥離可能限界線、９２は隠蔽層のうちはくり可能限界線によって分けられる剥離部分、９３は剥離可能限界線によって分けられる残存部分である。
【０１１７】
図４（B）において、くじ部分８５は図示しない基板シート上に設けられており、情報インキ層８６、ニス層８７、隠蔽層８８よりなる。ニス層８７は正三角形であり、隠蔽層８８はニス層８７に内接する円である。隠蔽層８８はニス層８７に接しているが、ニス層８７のうち、三角形の各頂点が隠蔽層８８よりも出ている。すなわち、ニス層８７は隠蔽層８８よりも面積が大きく、かつ、各頂点が隠蔽層８８よりも出ている状態である。隠蔽層８８よりも出ている各頂点によって接着テープが基板シートに貼着してしまうことを防いでいる。
【０１１８】
剥離可能限界線９１は、3つあるニス層８７と隠蔽層８８の接点のうち2つを結んだ線である。隠蔽層８８を剥がすために使用する接着テープは、その幅が、剥離可能限界線９１の長さ以下のものにしなければ、基板シート上に接着テープが貼着してしまうため好ましくない。また、接着テープを用いて隠蔽層８８を剥がす際には隠蔽層８８を全て剥がすことはできず、隠蔽層８８のうち剥離可能限界線９１によって分けられる残存部分９３は剥がすことができずに残る。なぜなら、ニス層８７は三角形なので、剥離可能限界線９１より先は徐々に狭まっていくからである。情報インキ層８６は、隠蔽層８８のうち、この剥離可能限界線９１で分けられる剥離部分９２側に設けられており、情報インキ層８６を目視するには、接着テープを、ニス層８７の３つの辺のうち剥離可能限界線９１に平行な辺の近辺に、基板シート上に接着テープが貼着しないように貼り、剥離可能限界線９１によって分けられる剥離部分９２を覆って、剥離可能限界線９１の近辺に基板シートに貼着しないように貼った後、引き剥がすことで可能となる。
【０１１９】
図４において、図４（A）、図４（B）それぞれの隠蔽層のうち、剥離可能限界線によって分けられる残存部分の大きさは、０．３５ｍｍ以上の大きさの文字が2文字以上設けることができる大きさであるのが好ましい。更に、ニス層の面積は、隠蔽層を剥がす際に基板シートに接着テープが貼着してしまうこと防ぐことはもちろんのこと、誤ってニス層が設けられていない部分に接着テープを貼着してしまうことを防ぐためにも隠蔽層よりも大きくする必要がある。また、家庭で使用されることが多い、１２ｍｍや１５ｍｍの幅の接着テープを採用することができるように、ニス層と隠蔽層を設計することが好ましい。
【０１２０】
また、図１から図４まで隠蔽層を円に固定したが、これに限定する必要はない。また、一つの隠蔽層で情報インキ層全てを隠蔽しているが、これに限定する必要は無く、情報インキ層を一部ずつ覆ってもよい。つまり、情報インキ層が「あたり」という文字の場合、「あ」と「た」と「り」を一文字ずつ覆うことも可能ということである。更に、少なくとも情報インキ層を隠蔽することができればよいので、極端な例を挙げれば、情報インキ層が「あたり」という文字である場合に、この「あたり」という文字を隠蔽するように、隠蔽層を「あたり」という文字にすることも可能である。ただし、このようにしてしまうと、隠蔽層を剥がす前に情報インキ層が何であるのかがわかってしまうので、好ましい隠蔽層とはいえない。
【０１２１】
図５、図６は本願発明の別の実施の形態を示したものである。図５は本実施の形態の一例を表した断面図であり、図６はそのくじ部分のみを積層順に展開した展開図である。図５、図６のくじ部分を抽選カードなどに設けた場合の上面図は図1（A）と同様であるため割愛する。図５において１０１は基板シート、１０２はくじ部分、１０３は下地インキ層、１０４は情報インキ層、１０５はニス層、１０６は隠蔽層、１０７は下地インキ層の直径、１０８は情報インキ層の端点から端点までの長さ、１０９はニス層１０５の直径、１１０は隠蔽層１０６の直径である。また、図６において、図６（A）は下地インキ層の上面図、図６（B）は情報インキ層の上面図、図６（C）はニス層の上面図、図６（D）は隠蔽層の上面図、（E）は全ての層を積層した後の通常の状態から見た上面図であり、１０２はくじ部分、１０３は下地インキ層、１０４は情報インキ層、１０５はニス層、１０６は隠蔽層、１０７は下地インキ層の直径、１０８は情報インキ層の端点から端点までの長さ、１０９はニス層１０５の直径、１１０は隠蔽層１０６の直径、１１１は下地インキ層１０３の中心、１１２はニス層１０９の中心、１１３は隠蔽層１０６の中心、１１４はくじ部分の中心である。
【０１２２】
図５、図６において、くじ部分１０２は基板シート１０１上に設けられており、下地インキ層１０３、情報インキ層１０４、ニス層１０５、隠蔽層１０６よりなる。下地インキ層１０３は情報インキ層１０４の端点から端点までの長さ１０８の最大値をその直径とする円の形をしており、基板シート１０１上に直接設けられている。情報インキ層１０４は「あたり」若しくは、「はずれ」を形成している層であり、下地インキ層１０３の上に、かつ、下地インキ層１０３の範囲から出ないようにして設けられている。ニス層１０５、隠蔽層１０６は共に円の形をしており、ニス層１０５、隠蔽層１０６のそれぞれの中心１１２、１１３が下地インキ層１０３の中心１１１と重なるように設けられている。下地インキ層１０３の直径１０７と隠蔽層１０６の直径１１０は略同じ長さであり、ニス層１０５の直径１０８は下地インキ層１０３と隠蔽層１０６の直径よりも長くなるように設計されている。したがって、正面から見ると、下地インキ層１０３と情報インキ１０４は見えない。また、ニス層１０５が隠蔽層１０６よりも面積が大きく、かつ、隠蔽層１０６の外周からニス層１０５が均等に出ているように見える。
【０１２３】
図１と同じ名前を付したものは同じものであるため説明を割愛し、下地インキ層１０３について説明する。下地インキ層１０３は情報インキ層１０４と任意の順に積層することができる層である。本実施の形態では情報インキ層１０４の下に設けられているが、これに限定するわけではなく、情報インキ層１０４の上に設けることもできる。また、下地インキ層１０３は文字、記号、図形、またはこれらの結合からなるものであり、情報インキ層１０４と少なくとも一部が重複するものである。本実施の形態では、下地インキ層１０３は四角形の集合からなる模様であり、情報インキ層１０４の一部と重複している。ここで、重複するとは、例えば、下地インキ層１０３と情報インキ層１０４を印刷方式で設けた場合、それぞれの層を形成する印刷部分が少なくとも一部は重なるということである。なお、下地インキ層１０３は、基板シート１０１の裏面から強い光を当てて抽選情報を最外層に影として写し出しても、写し出された影によって抽選情報の解読を困難にさせる役割を担うものであるため、たとえ情報インキ層１０４と重複しなくてもこの役割を担うことができれば重複する必要は無い。下地インキ層１０３によって、基板シート１０１の裏面から強い光を当てて、情報インキ層１０４を最外層に影として写しも、写し出された影によって情報インキ層１０４を解読することをより困難にすること、又は、情報インキ層１０４の影を写すことを阻止することができるようになる。すなわち、下地インキ層１０３を絵柄にして情報インキ層１０４の下に設ければ、基板シート１０１の裏面から強い光を当てて、情報インキ層１０４を最外層である隠蔽層１０６に写し出そうとしても、隠蔽層１０６には情報インキ層１０４の影だけでなく、下地インキ層１０３の影も一緒に写るので、情報インキ層１０４の解読を困難にすることができるし、また、下地インキ層１０３をベタとして情報インキ層１０４の下に設ければ、基板シート１０１の裏面から強い光を当てて、情報インキ層１０４を最外層である隠蔽層１０６に写し出そうとしても、ベタ塗りの下地インキ層１０３によって情報インキ層１０４の影を写し出すことを阻止することができるようになる。下地インキ層１０３を情報インキ層１０４の上に設けた場合も同様であり、下地インキ層１０３を絵柄にして情報インキ層１０４の上に設ければ、基板シート１０１の裏面から強い光を当てて、情報インキ層１０４を最外層である隠蔽層１０６に写し出そうとしても、隠蔽層１０６には、情報インキ層１０４の影だけでなく、下地インキ層１０３の影も一緒に写るので、情報インキ層１０４の解読を困難にすることができるし、また、下地インキ層１０３をベタとして情報インキ層１０４の上に設ければ、基板シート１０１の裏面から強い光を当てて、情報インキ層１０４を最外層である隠蔽層１０６に写し出そうとしても、ベタ塗りの下地インキ層１０３によって情報インキ層１０４の影を写し出すことを阻止することができるようになる。したがって、基板シート１０１の上に情報インキ層１０４と任意の順に積層される下地インキ層１０３を有しているため、基板シート１０１の裏面から強い光を当てて、情報インキ層１０４を最外層に影として写しも、写し出された影によって情報インキ層１０４を解読することをより困難にすること、又は、情報インキ層１０４の影を写すことを阻止することができるようになり、例えば、俗にグラビア印刷で微塗工紙と呼ばれている非常に薄く、表面強度の弱い紙を基板シート１０１に採用することも可能となる。更に、ニス層１０５を隠蔽層１０６よりも面積が大きくなるように、かつ、ニス層１０５が隠蔽層１０６の外周から均等に出るように設けているため、表面強度が弱い紙を採用しても紙剥けを生じさせずに隠蔽層１０６のみを剥がすことができる。
【０１２４】
図５、図６において、下地インキ層１０３は、情報インキ層１０４の端点から端点までの長さ１０８の最大値をその直径とする円であるが、これに限定する必要はない。情報インキ層１０４よりも小さくてもよいし、又は、情報インキ層１０４よりも大きくてもよい。例えば、基板シート１０１一面に下地インキ層１０３を設け、次に、下地インキ層１０３上の任意の個所に情報インキ層１０４、ニス層１０５、隠蔽層１０６という順に積層してゆくことも可能である。
【０１２５】
本願発明において、下地インキ層１０３は、情報インキ層１０４が基板シート１０１の裏面からの強い光によって隠蔽層１０６に影として写し出されるのを困難にする、もしくは、影として写し出されても、その影による抽選情報の解読を困難にさせるという役割を担うものであって、隠蔽層１０６によって隠蔽されるべきものではない。したがって、下地インキ層１０３は通常の状態で見えていてもかまわなく、下地インキ層１０３の全てを、隠蔽層１０６によって覆う必要はない。ニス層１０５も、隠蔽層１０６を剥がす際に、紙剥けすることを防止するために設けられるものであるため、隠蔽層１０６を紙剥けすることなく剥がすことができるように設けてあれば、下地インキ層１０３全てを覆う必要はない。ただし、ニス層１０５が覆う面積が大きければ大きいほど、基板シート１０１の何処に接着テープを貼着しても紙剥けすることなく隠蔽層１０６を剥がすことができるので、好ましいことは言うまでもない。
【０１２６】
また、図５、図６において、下地インキ層１０３は四角形の集合からなる模様であるが、これに限定する必要はない。下地インキ層１０３が、基板シート１０１の裏面から強い光を当てて抽選情報を最外層に影として写し出しても、写し出された影による抽選情報の解読を困難にさせるという役割を担うことができれば、下地インキ層１０３を文字、記号、図形、又はこれらの結合など、どのようなものにしてもよい。例えば、ベタでもよく、カラーの画像でもよく、文字の集合にしてもよい。ただし、情報インキ層１０４が「あたり」である場合に下地インキ層１０３を情報インキ層１０４と同じ大きさの文字で「あたり」とし、更に、情報インキ層１０４と重なるように設けたのでは、裏面から強い光を当てて隠蔽層１０６に情報インキ層１０４を影として写した場合に、その影をより濃くすることになりかねないので、好ましい下地インキ層１０３の形態とは言えない。さらに、情報インキ層１０４が「あたり」である場合に、下地インキ層１０３を情報インキ層１０４と同じ大きさの文字で「はずれ」として情報インキ層１０４と重なるように設けたり、または、情報インキ層１０４よりも小さい文字で、あたかも模様のように「はずれはずれはずれ…」と設けたりすると、隠蔽層１０６を剥がした際に、そのくじが「あたり」なのか「はずれ」なのかわからなくなり、混同を生じるため、好ましい下地インキ層１０３の形態とは言えない。しかし、下地インキ層１０３を、情報インキ層１０４よりも小さい文字で、かつ、情報インキ層１０４と同じものをあたかも模様のように設けることは前述したような混同を生じることも無く、また、情報インキ層１０４が影として隠蔽層１０６に写し出されてもその解読を困難にする役割を担うと考えられるので、採用可能な下地インキ層１０３の一形態といえる。この際には、下地インキ層１０３を、図５、図６のように、下地インキ層１０３が隠蔽層１０６によって隠蔽されるような大きさにしなければ、通常の状態でも情報インキ層１０４に何がかかれているのか解読されてしまう恐れが生ずるので、下地インキ層１０４の大きさに注意する必要がある。
【０１２７】
また、下地インキ層１０３の色、濃度は問わず、どのような色を用いてもよいし、どのような濃度にしてもよい。例えば、下地インキ層１０３を情報インキ層１０４の下に設け、かつ、ベタ塗りにする場合は、情報インキ層１０４よりも濃い色で下地インキ層１０３を設けた方が基板シート１０１の裏面から光を当てて影を写すことをより阻止できるので好ましいが、これに限る必要はない。なお、下地インキ層１０３を情報インキ層１０４の上に設ける場合は下地インキ層１０３によって情報インキ層１０４が見えなくならないように設ける必要がある。
【０１２８】
また、図５、図６において、ニス層１０５は隠蔽層１０６よりも面積が大きい円としたが、これに限定する必要はなく、図２、図３、図４に示すようにニス層１０５を変形することももちろん可能であり、図２、図３に示すように、ニス層１０５を、隠蔽層１０６よりも面積が大きく、かつ、隠蔽層１０６の外周の一部から出るように設け、更に、隠蔽層１０６を、ニス層１０５よりも面積が小さく、かつ、ニス層１０５の外周の一部から出るように設ける事も可能である。下地インキ層１０３を有し、更に、図２、図３に示すように、ニス層１０５を、隠蔽層１０６よりも面積が大きく、かつ、隠蔽層１０６の外周の一部から出るように設け、更に、隠蔽層１０６を、ニス層１０５よりも面積が小さく、かつ、ニス層１０５の外周の一部から出るように設けることによって、基板シート１０１の裏面から強い光を当てて、情報インキ層１０４を最外層である隠蔽層１０６に影として写し出して抽選情報を事前に読み取るという不正行為と共に、選択したくじ部分１０２の隠蔽層１０６を剥がしたとき、それがはずれくじであった場合に、あたかも剥がしていないかのように元に戻すという不正行為も防ぐことができるようになる。また、ニス層１０５が隠蔽層１０６よりも面積が大きく、かつ、隠蔽層１０６の外周よりも出るように設けられているため、紙剥けを生じることなく隠蔽層１０６を剥がすことができるのは言うまでもない。
【０１２９】
また、図５、図６において隠蔽層１０６を円に固定したが、これに限定する必要はない。また、一つの隠蔽層１０６で情報インキ層１０４全てを隠蔽しているが、これに限定する必要は無く、情報インキ層１０４を一部ずつ覆ってもよい。つまり、情報インキ層１０４が「あたり」という文字の場合、「あ」と「た」と「り」を一文字ずつ覆うことも可能ということである。更に、少なくとも情報インキ層１０４を隠蔽することができればよいので、極端な例を挙げれば、情報インキ層１０４が「あたり」という文字である場合に、この「あたり」という文字を隠蔽するように、隠蔽層１０６を「あたり」という文字にすることも可能である。ただし、このようにしてしまうと、隠蔽層１０６を剥がす前に情報インキ層１０４が何であるのかがわかってしまうので、好ましい隠蔽層１０６とはいえない。
【０１３０】
基板シート上に図５、図６のくじ部分を形成するには、まず基材シート１０１上に、下地インキ層１０３をグラビア印刷方式によって塗布し、次に、下地インキ層１０３に一部が重複するように情報インキ層１０４をグラビア印刷方式によって塗布し、次に、情報インキ層１０４を覆うように、かつ、まだ何も印刷されていない基板シート１０１上にもかかるようにニス層１０５をグラビア印刷方式で塗布し、次に、隠蔽層１０６をグラビア印刷方式で塗布している。図１と同じ名前を付した層についての説明は図１と同じである。本実施の形態では、下地インキ層にはロジン系樹脂を用いている。しかし、別段これに限定する必要は無く、通常のグラビア印刷に使用するインキを用いることができる。また、図１（A）に示すように、くじ部分１０２以外の基板シート１０１上に絵柄部分である見だしや絵柄部分である注意書きなどを設けることも可能である。くじ部分１０２以外の基板シート１０１上に絵柄部分を設ける手段には、下地インキ層１０３を基板シート一面に設けることによって絵柄部分も設ける手段を採用してもよく、絵柄部分は別に設けてから下地インキ層１０３を設けるという手段を採用してもよく、その組み合わせは自由である。また、塗布方法も塗布可能であればいずれの方法を採用してもよいが、図１の塗布方法と重複するため説明は割愛する。
【０１３１】
図７、図８は本願発明の別の実施の形態を示したものである。図７は本実施の形態の一例を表した断面図であり、図８はそのくじ部分のみを積層順に展開した展開図である。抽選カードなどに設けた場合の上面図は図1（A）と同様であるため割愛する。図７において１２１は基板シート、１２２はくじ部分、１２３は情報インキ層、１２４はニス層、１２５はインキ層、１２６は隠蔽層、１２７は情報インキ層の端点から端点の長さの最大値、１２８はニス層１２４の直径、１２９はインキ層１２５の直径、１３０は隠蔽層１２６の直径である。また、図８において、図８（A）は情報インキ層の上面図、図８（B）はニス層の上面図、図８（C）はインキ層の上面図、図８（D）は隠蔽層の上面図、図８（E）は全ての層を積層した後の通常の状態から見た上面図であり、１２２はくじ部分、１２３は情報インキ層、１２４はニス層、１２５はインキ層、１２６は隠蔽層、１２７は情報インキ層の端点から端点までの長さ、１２８はニス層１２４の直径、１２９はインキ層１２５の直径、１３０は隠蔽層１２６の直径、１３１はニス層の中心、１３２はインキ層の中心、１３３は隠蔽層の中心、１３４はくじ部分の中心である。
【０１３２】
図７、図８において、くじ部分１２２は基板シート１２１上に設けられており、情報インキ層１２３、ニス層１２４、インキ層１２５、隠蔽層１２６よりなる。情報インキ層１２３は「あたり」若しくは、「はずれ」を形成している層であり、基板シート１２１上に設けられている。ニス層１２４は、円の形をしており、情報インキ層１２３を覆うように、かつ、基板シート１２１上にもかかるようにして基板シート１２１上に設けられている。また、ニス層１２４の直径はインキ層１２５と隠蔽１２６層よりも長くなるように設計されている。インキ層１２５と隠蔽層１２６は、共に、情報インキ層１２３の端点から端点までの長さ１２７の最大値をその直径とする円であり、ニス層１２４の上に、インキ層１２５、隠蔽層１２６の順で情報インキ層１２３を覆うように積層されている。また、ニス層１２４、インキ層１２５、隠蔽層１２６は、それぞれの中心がくじ部分１３４の中心と重なるように設けられている。したがって、正面から見ると、情報インキ層１２３とインキ層１２５は隠蔽層１２６によって見えない。また、ニス層１２４が、隠蔽層１２６よりも面積が大きく、かつ、隠蔽層１２６の外周から均等に出ているように見える。
【０１３３】
図１と同じ名前を付したものは同じのもであるため説明を割愛し、インキ層１２５について説明する。インキ層１２５はニス層１２４の上に、隠蔽層１２６と任意の順に積層することができる層である。本実施の形態では、隠蔽層１２６の下に設けられているが、これに限定するわけではなく、隠蔽層１２６の上に設けることも可能である。また、インキ層１２５は文字、記号、図形、またはこれらの結合からなるものであり、情報インキ層１２３と少なくとも一部が重複するものである。本実施の形態では、インキ層１２５は四角形の集合からなる模様であり、情報インキ層１２３の一部と重複している。ここで、重複するとは、例えば、情報インキ層１２３とインキ層１２５を印刷方式で設けた場合、それぞれの層を形成する印刷部分が少なくとも一部は重なるということである。インキ層１２５を隠蔽層１２６の下に設けた場合は、情報インキ層１２３とインキ層１２５の間にニス層１２４が介在するが、ニス層１２４を通じて情報インキ層１２３とインキ層１２５とが重複するということである。また、インキ層１２５を隠蔽層１２６の上に設けた場合も、情報インキ層１２３とインキ層１２５の間に、ニス層１２４と隠蔽層１２６が介在するが、ニス層１２４と隠蔽層１２６を通じて情報インキ層１２３とインキ層１２５とが重複するということである。なお、インキ層１２５は、基板シート１２１の裏面から強い光を当てて抽選情報を最外層に影として写し出しても、写し出された影によって抽選情報の解読を困難にさせる役割を担うものであるため、たとえ情報インキ層１２３と重複しなくてもこの役割を担うことができれば重複する必要は無い。ニス層１２４の上に隠蔽層１２６と任意の順で積層できるインキ層１２５を有することによって、基板シート１２１の裏面から強い光を当てて、情報インキ層１２３を最外層に影として写しも、写し出された影によって情報インキ層１２３を解読することをより困難にすること、又は、情報インキ層１２３の影を写すことを阻止することができるようになる。すなわち、インキ層１２５を絵柄等にして隠蔽層１２５の下に設ければ、基板シート１２１の裏面から強い光を当てて、情報インキ層１２５を最外層である隠蔽層１２６に写し出そうとしても、隠蔽層１２６には情報インキ層１２３の影だけでなく、インキ層１２５の影も一緒に写るので、情報インキ層１２３の影だけを読み取ることを困難にすることができるし、また、インキ層１２５をベタにして隠蔽層１２６の下に設ければ、基板シート１２１の裏面から強い光を当てて、情報インキ層１２３を最外層である隠蔽層１２６に写し出そうとしても、ベタ塗りのインキ層１２５によって情報インキ層１２３の影を写し出すことを阻止することができるようになる。インキ層１２５を隠蔽層１２６の上に設けた場合も同様で、インキ層１２５を絵柄にして隠蔽層１２６の上に設ければ、基板シート１２１の裏面から強い光を当てて、情報インキ層１２３を最外層であるインキ層１２５に写し出そうとしても、最外層であるインキ層１２５には、情報インキ層１２３の影だけでなくインキ層１２５の絵柄も見えるので、情報インキ層１２３の影だけを読み取ることを困難にすることができるし、また、インキ層１２５をベタにして隠蔽層１２６の上に設ければ、基板シート１２１の裏面から強い光を当てて、情報インキ層１２３を最外層であるインキ層１２５に写し出そうとしても、ベタ塗りのインキ層１２５によって情報インキ層１２３の影を写し出すことを阻止することができるようになる。したがって、ニス層１２４の上に隠蔽層１２６と任意の順で積層されるインキ層１２５を有しているため、基板シート１２１の裏面から強い光を当てて、情報インキ層１２３を最外層に影として写し出しても、写し出された影による抽選情報の解読を困難にさせる事、又は、情報インキ層１２３の影を写し出すことを阻止することができるようになり、隠蔽層１２６を剥がす前に抽選情報を読み取ってしまうという不正を防ぐ事ができる。したがって、例えば、俗にグラビア印刷で微塗工紙と呼ばれている非常に薄く、表面強度の弱い紙を基板シート１２１に採用することも可能となる。また、ニス層１２４を隠蔽層１２６よりも面積が大きくなるように、かつ、ニス層が隠蔽層１２６の外周よりも均等に出るように設けられているため、紙剥けを生じることなく隠蔽層１２６を剥がすことができる。
【０１３４】
図７、図８において、インキ層１２５は、情報インキ層１２３の端点から端天までの長さの最大値１２７をその直径とする円であるが、これに限定する必要はない。例えば、その一部が情報インキ層１２３と重複するように、情報インキ層１２３よりも小さく設けてもよいし、もちろん、情報インキ層１２３よりも大きく設けてもよいし、基板シート１２１一面に設けてもよい。ただし、インキ層１２５を、隠蔽層１２６の下に設けても、隠蔽層１２６の上に設けても、どちらにしろニス層１２４の上にインキ層１２５が設けられることになる。ニス層１２４の上にインキ層１２５が設けられることによって、ニス層１２４の輪郭が不明確になり、隠蔽層１２６を剥がす際に接着テープが紙に貼着してしまう場合も考えられる。例えば、基板シート１２１上に部分的に情報インキ層１２３を設け、次に情報インキ層１２３を覆うようにニス層１２４を設け、次に、ニス層１２４も含めて基板シート１２１の上にインキ層１２４を一面に設け、次に、情報インキ層１２３のみを隠蔽するように部分的に隠蔽層１２６をインキ層１２４の上に設けた場合は、インキ層１２５によってニス層１２４の輪郭が不明確になってしまい、その結果、隠蔽層を剥がす際に接着テープを基板シート１２１に貼着してしまう可能性が生じてくる。したがって、インキ層１２５は、ニス層１２４の面積以下の大きさにし、かつ、ニス層１２４の外周から出ないように設けることが好ましい。更に言えば、隠蔽層１２６と同じ面積、同じ形状、同じ位置に設けることが好ましい。しかし、インキ層１２５を、ニス層１２４の輪郭がわからなくなるように設けたとしても、注意書きを設けることによって、ニス層１２４の輪郭を示すせば前述した可能性は低くなる。更に、インキ層１２５を隠蔽層１２６の上に設けることによって、ニス層１２４の輪郭だけでなく、隠蔽層１２６の輪郭をも不明確になってしまった場合も、注意書きを設けてニス層１２４と隠蔽層１２６の範囲をそれぞれ示すことが好ましい。
【０１３５】
また、図７、図８において、インキ層１２５は四角形の集合からなる模様であるが、これに限定する必要はない。インキ層１２５が、情報インキ層１２３が基板シート１２１の裏面からの強い光によって隠蔽層１２６に影として写し出されるのを阻止する、もしくは、影として写し出されても、その影による抽選情報の解読を困難にする、という役割を担うことができれば、インキ層１２５を文字、記号、図形、又はこれらの結合など、どのようなものにしてもよい。例えば、ベタでもよく、カラーの画像でもよく、文字の集合にしてもよい。ただし、情報インキ層１２３が「あたり」である場合に、インキ層１２５を情報インキ層１２３と同じ大きさの文字で「あたり」とし、更に、情報インキ層１２３と重なるように設けたのでは、裏面から強い光を当てて隠蔽層１２６に情報インキ層１２３を影として写した場合に、その影をより濃くすることになりかねないので、好ましいインキ層１２５の形態とはいえない。つまり、情報インキ層１２３と全く同じになるようにインキ層１２５を設けることは、好ましいインキ層１２５の形態とはいえない。しかし、情報インキ層１２３が「あたり」である場合に、インキ層１２５を情報インキ層１２３よりも小さい文字で、あたかも模様のように「あたりあたり…」と設けることは、情報インキ層１２３が影として隠蔽層１２６に写し出されてもその解読を困難にする役割を担うと考えられるので、採用可能なインキ層１２５の一形態といえる。
【０１３６】
また、インキ層１２５の色、濃度は問わず、どのような色を用いてもよいし、どのような濃度にしてもよい。情報インキ層１２３よりも濃い色にすることによって、隠蔽層１２６を剥がす前に抽選情報を読み取るという不正を効果的に防ぐ事ができるので好ましい。しかしこれに限定する必要は無い。

インキ層１２５を文字、記号、図形、もしくはこれらの結合からなる模様などにすると、美観を向上させることができる。例えば、隠蔽層の下に設けるインキ層１２５を文字、記号、図形、もしくはこれらの結合からなる模様にすると、通常の状態で見たときにあたかも和紙のすかし模様のように、隠蔽層１２６からインキ層１２５の絵柄が見えるようになり、美観を向上することができる。また、隠蔽層の上に設けるインキ層１２５を文字、記号、図形、もしくはこれらの結合からなる模様にすると、通常の状態で見たときに設けた模様の間から隠蔽層が見えるようになり、美観を向上させることができる。このとき、模様などを、白抜きにして設けた方が、情報インキ層１２３と重複する部分が増えることになり、インキ層１２５によっても情報インキ層１２３を隠蔽することになるので好ましい。
【０１３８】
また、図７、図８において、ニス層１２４は隠蔽層１２６よりも面積が大きい円としたが、これに限定する必要はなく、図２、図３、図４に示すようにニス層１２４を変形することももちろん可能であり、図２、図３に示すように、ニス層１２４を、隠蔽層１２６よりも面積が大きく、かつ、隠蔽層１２６の外周の一部から出るように設け、更に、隠蔽層１２６を、ニス層１２４よりも面積が小さく、かつ、ニス層１２４の外周の一部から出るように設ける事も可能である。インキ層１２５を有し、更に、図２、図３に示すように、ニス層１２４を、隠蔽層１２６よりも面積が大きく、かつ、隠蔽層１２６の外周の一部から出るように設け、更に、隠蔽層１２６を、ニス層１２４よりも面積が小さく、かつ、ニス層１２４の外周の一部から出るように設けることによって、基板シート１２１の裏面から強い光を当てて、情報インキ層１２３を最外層である隠蔽層１２６に影として写し出して抽選情報を事前に読み取るという不正行為と共に、選択したくじ部分１２２の隠蔽層１２６を剥がしたときそれがはずれくじであった場合に、あたかも剥がしていないかのように元に戻すという不正行為も防ぐことができるようになる。また、ニス層１２４が隠蔽層１２６よりも面積が大きく、かつ、隠蔽層１２６の外周よりも出るように設けられているため、紙剥けを生じることなく隠蔽層１２６を剥がすことができるのは言うまでもない。
【０１３９】
また、図７、図８において隠蔽層１２６を円に固定したが、これに限定する必要はない。また、一つの隠蔽層１２６で情報インキ層１２３全てを隠蔽しているが、これに限定する必要は無く、情報インキ層１２３を一部ずつ覆ってもよい。つまり、情報インキ層１２３が「あたり」という文字の場合、「あ」と「た」と「り」を一文字ずつ覆うことも可能ということである。更に、少なくとも情報インキ層１２３を隠蔽することができればよいので、極端な例を挙げれば、情報インキ層１２３が「あたり」という文字である場合に、この「あたり」という文字を隠蔽するように、隠蔽層１２６を「あたり」という文字にすることも可能である。ただし、このようにしてしまうと、隠蔽層１２６を剥がす前に情報インキ層１２３が何であるのかがわかってしまうので、好ましい隠蔽層１２６とはいえない。
【０１４０】
基板シート上に図７、図８のくじ部分を形成するには、まず基材シート１２１上に、情報インキ層１２３をグラビア印刷方式によって塗布し、次に、情報インキ層１２３を覆うように、かつ、まだ何も印刷されていない基板シート１２１上にもかかるようにニス層１２４をグラビア印刷方式で塗布し、次に、ニス層の上にインキ層１２５をグラビア印刷方式で塗布し、次に、インキ層１２４の上に隠蔽層１２６をグラビア印刷方式で塗布している。図１と同じ名前を付した曽についての説明は図1と同じである。インキ層は、隠蔽層と共に接着テープによって剥がされなくてはならない。このようにするには、隠蔽層と樹脂層を同じにすればよい。したがって、インキ層は、ニトロセルロース系樹脂の藍インキによって形成されている。よって、インキ層は、ニス層とは低密着性、低接着性を示し、隠蔽層とは強密着性、強接着性を示しており、接着テープによって隠蔽層を剥がす際には、隠蔽層と一緒にインキ層も剥がすことができる。本実施の形態ではインキ層はニトロセルロース系の藍インキとしたが、別段これに限定する必要はない。隠蔽層と共に剥離可能であれば、どのようなものを用いてもよく、例えば、銀インキでもよいし、何色も組み合わせてカラーの画像にしてもよい。また、図１（A）に示すように、くじ部分１２２以外の基板シート１２１上に絵柄部分である見だしや絵柄部分である注意書きなどを設けることも可能である。くじ部分１２２以外の基板シート１２１上に絵柄部分を設ける手段には、インキ層１２５を基板シート一面に設けることによって絵柄部分も設ける手段を採用してもよく、絵柄部分は独立させて設けるという手段を採用してもよく、その組み合わせは自由である。また、塗布方法も塗布可能であればいずれの方法を採用してもよいが、図１の塗布方法と重複するため説明は割愛する。
【０１４１】
次に図９を参照して、インキ層の様式の一例について説明する。
【０１４２】
図９は別の実施の形態を表すくじ部分の展開図であり、基板シートと、基板シートの上に位置し、抽選情報を有する情報インキ層と、少なくとも前記抽選情報を覆うように基板シート上に設けられたニス層と、前記ニス層の上に位置し、ニス層と剥離可能に設けられた偽装情報インキ層と、前記偽装情報インキ層の上に位置し、少なくとも前記抽選情報と偽装情報を隠蔽し、かつ、偽装情報インキ層と共に剥離可能に設けられた隠蔽層と、を有し、前記ニス層を少なくとも、隠蔽層よりも面積が大きく、かつ、隠蔽層の外周よりも出るように設けた事を特徴とする印刷物のくじ部分を展開した展開図である。抽選カードなどに設けた場合の上面図は図1（A）と同様であるため割愛し、断面図は図７と同様であるため割愛する。図９（A）は情報インキ層の上面図、図９（B）はニス層の上面図、図９（C）はインキ層である偽装情報インキ層の上面図、図９（D）は隠蔽層の上面図、図９（E）は全ての層を積層した後の通常の状態から見た上面図である。また、図９において１４０はくじ部分、１４１は情報インキ層、１４２はニス層、１４３はインキ層である偽装情報インキ層、１４４は隠蔽層、１４５は情報インキ層の端点から端点までの長さ、１４６はニス層１４２の直径、１４７はインキ層である偽装情報インキ層１４３の端点から端点までの長さ、１４８は隠蔽層１４４の直径、１４９は情報インキ１４１の中心、１５０はニス層１４２の中心、１５１はインキ層である偽装情報インキ層１４３の中心、１５２は隠蔽層１４４の中心、１５３はすべての層を積層後のくじ部分１４０の中心である。
【０１４３】
図９において、くじ部分１４０は図示しない基板シート上に設けられており、情報インキ層１４１、ニス層１４２、インキ層である偽装情報インキ層１４３、隠蔽層１４４よりなる。情報インキ層１４１は「あたり」、若しくは「はずれ」を形成している層であり、基板シート上に直接設けられている。ニス層１４２は円の形をしており、情報インキ１４１層を覆い、かつ、基板シート上にもかかるように基板シート上に設けられている。また、ニス層１４２の直径１４６は、隠蔽層１４４の直径１４８より長くなるように設計されている。インキ層である偽装情報インキ層１４３は、ニス層１４２の上に設けられており、偽装の抽選情報である「あたり」、若しくは「はずれ」を形成している。また、偽装情報インキ層１４３は、情報インキ層１４１と大きさを同じにし、情報インキ層１４１と重複するように設けられている。隠蔽層１４４は、情報インキ層１４１の端点から端点までの長さ１４５の最大値をその直径とする円であり、偽装情報インキ層１４３の上に設けられ、情報インキ層１４１と偽装情報インキ層１４３とを隠蔽している。全ての層はその中心がくじ部分の中心１５３に重なるように情報インキ層１４１、ニス層１４２、偽装情報インキ層１４３、隠蔽層１４４の順に積層されている。ここで、情報インキ層１４１と偽装情報インキ層１４３の中心とは、それぞれの水平方向の中点と垂直方向の中点が重なる点である。したがって、正面から見ると情報インキ層１４１と偽装情報インキ層１４３は隠蔽層１４４によって見えない。また、ニス層１４２が隠蔽層１４４よりも面積が大きく、隠蔽層１４４の外周から均等に出ているように見える。
【０１４４】
図１と同じ名前を付したものは同じものであるため説明を割愛し、インキ層である偽装情報インキ層１４３について説明する。インキ層である偽装情報インキ層１４３は、偽装の抽選情報を有するインキ層であり、基板シートの裏面から強い光を当てて情報インキ層１４１を最外層に写し出そうとしたとき、情報インキ層１４１が有する抽選情報以外の抽選情報（偽装抽選情報）を最外層に写し出す役割を担う層である。偽装情報インキ層１４３によって、情報インキ層１４１が「当選」を有しているのか、「落選」を有しているのかを困難にさせることができる。ここで、偽装の抽選情報とは、情報インキ層１４１が有する抽選情報以外の抽選情報であり、例えば、情報インキ層１４１が有する抽選情報とは反対の意味を表す情報等である。
【０１４５】
図９のくじ部分は、あたりくじを示しており、情報インキ層１４１には「あたり」という文字が設けられているのに対し、偽装情報インキ層に１４３は、はずれくじに設ける「はずれ」という文字が設けられている。更に、この「はずれ」という文字は、はずれくじの「はずれ」とまったく同じになるように設けられている。偽装情報インキ層１４３と情報インキ層１４１とは、垂直方向の端点から端点までの長さの最大値と水平方向の端転から端点までの長さ最大値が同じになるように、かつ、それぞれの中心が重なるように設けられている。すなわち、ニス層１４２が間に介在するが、情報インキ層１４１が有する「あたり」という文字と偽装情報インキ層１４３が有する「はずれ」という文字が上下に重複するように設けられている。
【０１４６】
したがって、偽装情報インキ層１４３を有しているため、基板シートの裏面から強い光を当てて、情報インキ層１４１を最外層に影として写し出し、その影によって抽選情報を解読しようとしても、そのくじ部分があたりくじなのかはずれくじなのか判断することを困難にすることができる。すなわち、基板シートの裏面から強い光を当てて、情報インキ層１４１を最外層である隠蔽層１４４に影として写し出すと、情報インキ層１４１の有する「あたり」という文字と、偽造情報インキ層１４３の有する「はずれ」という文字が重なったものが見えることになる。文字と文字が重なっているため、どのようなものが書かれているのか判断することは困難であるし、たとえ、「あたり」と「はずれ」という文字が重なったものであると理解できても、情報インキ層１４１が「あたり」を有しているのか、「はずれ」を有しているのかを判断することは非常に困難である。よって、基板シート上にいくつもくじ部分１４０を設けた抽選カード等において、どのくじ部分１４０があたりくじであるのかを判断することを困難にすることができる。更に、ニス層１４２を隠蔽層１４４よりも面積を大きく、かつ、隠蔽層１４４の外周よりも出るように設けているため、紙剥けを生じることなく、隠蔽層１４４を剥離することができる。
【０１４７】
また、隠蔽層１４４は偽装情報インキ層１４３の上に位置し、情報インキ層１４１と偽装情報インキ層１４３を隠蔽している。隠蔽層１４４が抽選情報だけでなく、偽装情報インキ層１４３をも隠蔽するのは、偽装情報インキ層１４３が偽装の抽選情報１４３を有することによって、基板シートの裏面から強い光を当てて情報インキ層１４１を最外層に写し出したとき、情報インキ層１４１が「当選」を有しているのか、「落選」を有しているのかを困難にさせることが可能となるので、通常の状態で偽装情報インキ層１４３を見ることができてしまうと、情報インキ層１４１が有する抽選情報が何であるかがわかってしまうからである。
【０１４８】
また、図９において、ニス層１４２は隠蔽層１４４よりも面積が大きい円としたが、これに限定する必要はなく、図２、図３、図４に示すようにニス層１４２を変形することももちろん可能であり、図２、図３に示すように、ニス層１４２を、隠蔽層１４４よりも面積が大きく、かつ、隠蔽層１４４の外周の一部から出るように設け、更に、隠蔽層１４４を、ニス層１４２よりも面積が小さく、かつ、ニス層１４２の外周の一部から出るように設ける事も可能である。偽装情報インキ層１４３を有し、更に、図２、図３に示すように、ニス層１４２を、隠蔽層１４４よりも面積が大きく、かつ、隠蔽層１４４の外周の一部から出るように設け、更に、隠蔽層１４４を、ニス層１４２よりも面積が小さく、かつ、ニス層１４２の外周の一部から出るように設けることによって、基板シートの裏面から強い光を当てて、情報インキ層１４１を最外層である隠蔽層１４４に影として写し出して抽選情報を事前に読み取るという不正行為と共に、選択したくじ部分１４０の隠蔽層１４４を剥がしたときそれがはずれくじであった場合に、あたかも剥がしていないかのように元に戻すという不正行為も防ぐことができるようになる。また、ニス層１４２が隠蔽層１４４よりも面積が大きく、かつ、隠蔽層１４４の外周よりも出るように設けられているため、紙剥けを生じることなく隠蔽層１４４を剥がすことができるのは言うまでもない。
【０１４９】
また、本実施の形態において、隠蔽層１４４は情報インキ層１４１の端点から端点までの長さ１４５の最大値をその直径とする円としたが、これに限定する必要はない。すくなくとも、情報インキ層１４１と偽装情報インキ層１４３を隠蔽することができればどのような形にしてもよい。また、本実施の形態では、情報インキ層１４１と偽装情報インキ層１４３は、ニス層１４２がその間に介在するが、上下に重複しているため、影として隠蔽層１４４に写し出されたときは文字として読むことができない。したがって、例えば、情報インキ層１４１と偽装情報インキ層１４３が重複した形どおりに隠蔽層１４４の形を形成しても、情報インキ層１４１が抽選情報と偽装情報のどちらを有しているのか判断することはできないため、情報インキ層１４１と偽装情報インキ層１４３が重複した形どおりに隠蔽層１４４の形を形成することも可能である。また、このように、情報インキ層１４１と偽装情報インキ層１４３が重複した形どおりに隠蔽層１４４の形を形成すると隠蔽層１４４の原料を最小限に押えることが可能となる。
【０１５０】
更に、本実施の形態において、偽装情報インキ層１４３はニス層１４２との接着力が弱く、隠蔽層１４４との接着力が強いため、隠蔽層１４４と共に剥がされる。よって、隠蔽層１４４を剥がした後は情報インキ層１４１のみを目視することが可能となる。また、偽装情報インキ層１４３は、隠蔽層１４４と共に剥がされるため、引き剥がした後の接着テープに貼着している。例えば、くじ部分１４０がはずれくじである場合には、隠蔽層１４４を剥がすと「はずれ」という文字が基板シート上に現れ、引き剥がした後の接着テープに「あたり」という文字が貼着することになる。したがって、接着テープを見ると「あたり」という文字が隠蔽層１４４と共に見えることになるので、接着テープにある「あたり」という文字を指して「『あたり』という文字を剥がしたのだからこれはあたりくじである」、というような誤解が生じる可能性もある。このような事態を招かないようにするには、あたりくじの見本をくじ部分の近くに設けるとよい。
【０１５１】
また、本実施の形態では、偽装情報インキ層１４３をはずれくじに設ける情報インキ層１４１と同じものとしたが、これに限定する必要はない。更に、あたりくじにのみ当選という情報を提供するものを設けるタイプのくじにおいても、偽装情報インキ層１４３を設けることによって、事前に抽選情報を読み取るという不正行為を効果的に防ぐことが可能となる。すなわち、あたりくじにのみ「あたり」などの当選という情報を提供するものが情報インキ層１４１に形成され、はずれくじの情報インキ層１４１には何も形成されていないということをもって落選とするタイプのくじにおいて、はずれくじの偽装情報インキ層１４３に、あたりくじの情報インキ層１４１に設けた抽選情報と同じものをあたりくじの情報インキ層１４１と同じように設ければ、基板シートの裏面から強い光を当てて、情報インキ層１４１を最外層に影として写し出しても、すべてのくじ部分１４０の最外層に当選に該当する情報が影として写し出されることになり、どのくじ部分が本当のあたりくじなのかを判断することを非常に困難にすることができるようになる。このようにすると、あたりくじは情報インキ層１４１、ニス層１４２、隠蔽層１４４を有するのに対し、はずれくじはニス層１４２、偽装情報インキ層１４３、隠蔽層１４４を有するようになるので、それぞれのくじ部分１４０全体の厚みは同じになるが、あたりくじは基板シート上に情報インキ層１４１を設け、情報インキ層１４１の上にニス層１４２が積層され、更にその上に隠蔽層１４４が積層されるのに対し、はずれくじは基板シート上にニス層１４２が設けられ、ニス層１４２の上に偽装情報インキ層１４３が積層され、更にその上に隠蔽層１４４が積層されるため、はずれくじの隠蔽層１４４にのみ、偽装情報インキ層１４３による凹凸ができてしまい、どのくじ部分がはずれくじかわかってしまうことも考えられる。したがって、隠蔽層１４４を厚く設けるか、若しくは、隠蔽層１４４にできる凹凸をそろえるために、あたりくじに偽装情報インキ層１４３を、はずれくじに情報インキ層１４１をそれそれ設けるとよい。このとき、基板シートの裏面から強い光を当てた時に、全てのくじ部分がすくなくとも当選に該当する抽選情報を隠蔽層１４４に影として写し出すように、あたりくじの情報インキ層１４１が有する抽選情報と、はずれくじの情報インキ層１４１が有する抽選情報の種類をそれぞれ違うものにするとよい。例えば、あたりくじの情報インキ層１４１を文字からなる「あたり」にし、はずれくじの情報インキ層１４１を図形からなる模様にして、あたりくじには偽装情報インキ層１４３にはずれくじの情報インキ層１４１を、はずれくじには偽装情報インキ層１４３にあたりくじの情報インキ層１４１をそれぞれ設ければ、あたりくじとはずれくじとで隠蔽層１４４にできる凹凸の差がなくなり、かつ、基板シートの裏面から強い光を当てても、全てのくじ部分が「あたり」という文字を隠蔽層１４４に影として写し出すため、どれがあたりくじかの判断を困難にすることが可能になる。別段、これらの形態に限定する必要は無く、情報インキ層と偽装情報インキ層をどのように設計してもよい。
【０１５２】
図１０、図１１は本願発明の別の実施の形態を示したものである。図１０において、１６０は冊子体、１６１は冊子体の綴じ部、１６２は冊子体の本文、１６３は冊子体の１頁片、１６４はくじ部分を有する抽選シート、１６５は左切り取り線、１６６は上切り取り線、１６７は抽選シートの右辺、１６８は抽選シートの下辺、１６９はくじ部分、１７０はニス層、１７１は隠蔽層、１７２は見だし部分である。
【０１５３】
図１０において、冊子体１６０は無線綴じ方式の冊子であり、いくつかの折丁を綴じ部１６１において綴じ、更に表紙を設けたものである。抽選シート１６４は、いくつかの折丁のうち、一つの折の１頁片１６３内に本文１６２と共に設けられている。抽選シート１６４は長方形をしており、その右辺１６７が冊子体１６０の小口を形成し、また、その下片１６８が冊子体の地を形成している。また、抽選シートの左辺と上辺は切り取り可能になっており、抽選シート１６４が取り外し可能になっている。抽選シート１６４は、本願発明の請求項１乃至請求項６何れか記載の印刷物である。具体的には、当選と落選のうちどちらかの情報を有しているくじ部分１６９が９個設けられており、３つずつ、均等に並んでいる。図示しないが、抽選シート１６４の裏面には宛先等が書かれており、左切り取り線１６５と上切り取り線１６６によって切り取られた抽選シート１６４は、１枚の葉書となる。本実施の形態では、印刷物である抽選シート１６４を折丁の１頁片１６３内に設け、無線綴じで綴じる方法を採用しているが、これに限定するものではない。例えば、折丁の１頁片１６３全てにくじ部分を設けてもよく、更には、１折丁全てにくじ部分を設けてもよい。また、綴じ方も、公知の綴じ方式を採用することができ、例えば、中綴じ、アジロ綴じ、平綴じ等の方式を採用することができる。
【０１５４】
本実施の形態の冊子体１６０の用途は雑誌であり、抽選シート１６４を使用した懸賞が行われている。この場合、懸賞主催者は出版社又は広告主であり、懸賞参加者は雑誌を購入した読者となる。懸賞参加者は抽選シート１６４を有する冊子体である雑誌を購入し、９個あるくじ部分１６９のうち一つを選択し、そのくじ部分１６９の隠蔽層１７１を接着テープによって剥がし、当選の場合は左切り取り線１６５と上切り取り線１６６とを切りとって、抽選シート１６４の裏面にされた宛先に送付することにより、商品を入手することができる。本願発明によれば、くじ部分１６９の隠蔽層１７１は固く強固であるため、傷がつきにくい。よって、隠蔽層１７１を剥がさないくじ部分１６９がある状態でポストに投函しても、他の郵便物とこすり合うことによって、剥がしていない隠蔽層１７１が剥がされてしまうことはないため、剥がさない隠蔽層１７１がある状態ままポストに投函することが可能である。このようにすることによって、より公正な抽選シート１６８を作成することが期待できる。本実施の形態では、冊子体１６０は雑誌であるが、これに限定するわけではない。本願発明によれば、例えば、ゲームの本や幼児の学習用の本として、本文中の所々にくじ部分を設けるような本を作成することも可能である。
【０１５５】
また、本願発明によれば、基板シートに薄い紙を採用することができるので、折丁の折の種類もどのようなものでも採用することが可能である。例えば、基板シート上の任意の場所にくじ部分１６９を設けてから、図１１（A）に示すような二つ折（４ページ折）、図１１（B）に示すような四つ折（４ページ折）、図１１（C）に示すような１２ページ折、図１１（D）に示すような１６ページ折、図１１（E）に示すような巻き三つ折（片観音折）、図１１（F）に示すような外三つ折（Z折）、図１１（G）に示すような内巻き四つ折（両観音折）等の公知の折り方を採用することが可能である。また、基板シート上の任意の場所に本願発明のくじ部分を設け、図１１に示すような折を採用して、パンフレットや広告紙を作成すれば、より宣伝効果を高めることが期待できる。
【０１５６】
【発明の効果】
本願発明の請求項１によれば、ニス層を、少なくとも抽選情報を隠蔽する隠蔽層よりも面積が大きく設け、かつ、ニス層の一部が隠蔽層の外周よりも出るように設けるとともに、隠蔽層の一部がニス層の外周よりも出るように設けているため、ニス層が紙の表面を保護する役割を果たし、接着テープによる紙剥けを防ぐ役割を担う。したがって、基板シートに表面強度の弱い紙を採用して、接着テープによって剥離可能な隠蔽層を施しても、紙剥けを生ずることなく隠蔽層を剥がすことが可能であるとともに、ニス層の外周よりも出るように設けられた隠蔽層の一部は剥離されずに基板シート上に残るため、隠蔽層を元に戻す不正行為を防止することが可能であるという作用効果を奏する。
【０１５７】
また、本願発明の請求項２によれば、基板シートの上に情報インキ層と任意の順で積層することができる下地インキ層を有しているため、基板シートの裏面から強い光を当てて抽選情報を最外層に影として写しだしても、写し出された影による抽選情報の解読を困難にさせるという役割を下地インキ層が担う。したがって、基板シートに薄い紙を採用しても、基板シートの裏面から強い光を当てて、抽選情報を事前に読み取るという不正行為を防ぐ事が可能であるという作用効果を奏する。
【０１５８】
また、本願発明の請求項３によれば、ニス層の上に隠蔽層と共に剥離可能なインキ層を有しているため、基板シートの裏面から強い光を当てて抽選情報を最外層に影として写しだしても、写し出された影による抽選情報の解読を困難にさせるという役割をインキ層が担う。したがって、基板シートに薄い紙を採用しても、基板シートの裏面から強い光を当てて、抽選情報を事前に読み取るという不正行為を防ぐ事が可能であるという作用効果を奏する。
【０１５９】
また、本願発明の請求項４によれば、インキ層が、情報インキ層が有する抽選情報以外の抽選情報である偽装の抽選情報を有しているため、基板シートの裏面から強い光を当てて抽選情報を最外層に影として写しだしても、写し出されて影による抽選情報の解読を困難にさせるという役割を、偽装の抽選情報を有しているインキ層が担う。したがって、基板シートに薄い紙を採用しても、基板シートの裏面から強い光を当てて、抽選情報を事前に読み取るという不正行為を防ぐ事が可能であるという作用効果を奏する。
【０１６０】
また、本願発明の請求項５によれば、隠蔽層の上に隠蔽層と共に剥離可能なインキ層を有しているため、基板シートの裏面から強い光を当てて抽選情報を最外層に影として写しだしても、写し出された影による抽選情報の解読を困難にさせるという役割をインキ層が担う。したがって、基板シートに薄い紙を採用しても、基板シートの裏面から強い光を当てて、抽選情報を事前に読み取るという不正行為を防ぐ事が可能であるという作用効果を奏する。
【０１６１】
また、本願発明の請求項６によれば、情報インキ層を網点面積率が略３０％以下になるように設けているため、基板シートの裏面から強い光を当てて情報インキ層を最外層に写し出そうとすることを、防ぐことが可能であるという作用効果を奏する。また、本願発明の請求項７によれば、冊子体（例えば、雑誌、書籍カタログ、パンフレット等）に、くじ等を提供することが可能となる。また、この提供されるくじ等は、本文と同じ頁に設けることが可能であるので、より薄く、持ち運びやすい冊子体を提供することが可能であるという作用効果を奏する。

Print lottery information consisting of characters, symbols, graphics, etc. on the substrate sheet, provide a varnish layer by a printing method so as to cover the lottery information, and further print a concealment layer to conceal the lottery information on the varnish layer The printed matter provided by the method is used in speed lotteries and games. These printed materials cannot see the lottery information in a normal state, but the lottery information can be seen by peeling the masking layer using an adhesive tape. In other words, the lottery information can be viewed by sticking the adhesive tape on the concealing layer and then peeling off the adhesive tape, peeling between the varnish layer and the concealing layer and peeling off the concealing layer. .
[0003]
However, the printed matter described above has a problem that it is difficult to employ paper having low surface strength for the substrate sheet.
[0004]
That is, in order to peel off the masking layer, the adhesive tape must be attached to the masking layer and then peeled off. When adhering the adhesive tape to the concealing layer, it is necessary to adhere the concealing layer so as to cover the concealing layer, so that the adhesive tape also adheres to the substrate sheet. When paper with low surface strength is used for the substrate sheet, the paper peels off due to the adhesive force of the adhesive tape when peeling off, and the lottery information is also peeled off with the paper, which not only impairs the appearance but also reads the lottery information. It becomes difficult. If the lottery information cannot be read when the concealing layer is peeled in this way, the lottery function will not be provided. Therefore, paper having a high surface strength has to be used for the substrate sheet so that it can withstand the adhesive force of the adhesive tape, and the types of paper that can be used for the substrate sheet have been limited.
[0005]
In addition, in the Japanese Patent No. 2711772, the applicant of the present application shows a printed matter in which the concealing layer is hard and strong and can be enclosed in a magazine. This is because a printed matter having a type of concealment layer that reads the lottery information by scraping the concealment layer by scratching with a nail or a coin is relatively soft so that the concealment layer can be scraped off. In this case, the problem of being unable to bind is solved by rubbing against other folds at the time of bookbinding. However, even when the paper having a low surface strength is used for the substrate sheet, the above-described invention cannot solve the problem that the paper peels off when the masking layer is peeled off using the adhesive tape.
[0006]
[Problems to be solved by the invention]
Therefore, the present invention has been made in view of the problems of the prior art, and the object of the present invention is to use paper having low surface strength for the substrate sheet and to provide a concealing layer that can be peeled off with an adhesive tape. It is another object of the present invention to provide a printed matter that can peel off the masking layer without causing paper peeling.
[0007]
[Means for Solving the Problems]
  In order to solve such a problem, claim 1 of the present invention provides a substrate sheet, an information ink layer positioned on the substrate sheet and having lottery information, and provided on the substrate sheet so as to cover at least the information ink layer. A varnish layer formed on the varnish layer, concealing at least the lottery information and detachably provided from the varnish layer, wherein the varnish layer is at least the concealment layer. Larger thanProvided,And,Part of the varnish layerProvided to protrude from the outer periphery of the concealing layerAnd a part of the concealing layer should be provided beyond the outer periphery of the varnish layer.It is a printed matter characterized by.
[0008]
  That is, according to claim 1 of the present invention, the varnish layer has a larger area than the concealment layer that conceals at least the lottery information.Provided,And,Part of the varnish layerProvided to protrude from the outer periphery of the concealing layerIn addition, provide a part of the concealing layer so that it protrudes from the outer periphery of the varnish layer.Therefore, even if paper with low surface strength is used for the substrate sheet and a concealing layer that can be peeled off with an adhesive tape is applied, it is possible to peel off the concealing layer without causing paper peeling.At the same time, a part of the concealing layer provided so as to protrude from the outer periphery of the varnish layer remains on the substrate sheet without being peeled off, so that it is possible to prevent an illegal act of returning the concealing layer to its original state.
[0009]
  That is, the area of the varnish layer is at least larger than the concealment layer.Provided,And,Part of the varnish layerSince it is provided so as to protrude from the outer periphery of the hiding layer, the varnish layer plays a role in protecting the paper surface and plays a role in preventing paper peeling due to the adhesive tape.In addition, since the part of the concealing layer is provided so as to protrude from the outer periphery of the varnish layer, when the concealing layer is peeled off by the adhesive tape, the part of the concealing layer that protrudes from the outer periphery of the varnish layer is present on the substrate sheet. Therefore, when trying to restore the peeled-off concealment layer, the joint between the part remaining on the substrate sheet and the part that was restored to the original was overlooked, and it remained on the substrate sheet. Even if an attempt is made to provide the concealment layer after the concealment layer has been removed, the substrate sheet and the concealment layer remaining on the substrate sheet are strongly bonded. Since it is determined that the act has been performed, a part of the hiding layer that protrudes from the outer periphery of the varnish layer plays a role of preventing an illegal act of returning the hiding layer.
[0010]
If the varnish layer and the concealing layer overlap so as to overlap in the same area as before, when the adhesive tape is adhered to the concealing layer in order to peel off the concealing layer, the adhesive tape also adheres to the paper As a result, the paper is peeled off, and as a result, the information ink layer is also peeled off together with the paper. However, in claim 1 of the present invention, since the varnish layer is expanded more than the concealment layer, the adhesive tape is attached to the varnish layer instead of paper, and does not cause paper peeling, and only the concealment layer is formed. It can be peeled off.
[0011]
The surface of this varnish layer has little friction, so the adhesion with the adhesive tape paste is weak, and furthermore, the ink forming the varnish layer is soaked in the paper, so that the varnish layer is peeled off by the adhesive tape. There is nothing.
[0012]
Therefore, according to claim 1 of the present invention, since the varnish layer is provided so as to have at least an area larger than the concealing layer and come out from the outer periphery of the concealing layer, paper having low surface strength is provided on the substrate sheet. Even if it is adopted, it functions as a lottery.
[0013]
Here, the printed matter includes, for example, a card, a game card, a flyer, direct mail, a telegram mount, a paper packaging container, a calendar, a paper stationery, and the like. The card may be any card-like card, such as a card distributed at a party, a greeting card, a postcard, a business card, or a printed card in a pocket tissue. The game card may be any card-like card used for play as long as it is made of paper, such as karuta, playing cards, and hanafuda. As long as the flyer has an advertising function, it may be in the form of a fold or a sheet, for example, a newspaper roll-in flyer, a leaflet, a street distribution flyer, a pamphlet or the like. The direct mail may be any envelope shape, and the telegram mount may be any shape that can hold the telegram paper. The paper packaging container may be any paper as long as it can be printed with paper that is processed into a three-dimensional object shape. For example, a paper box for confectionery, a paper pack for beverages, wrapping paper, a paper bag, a cardboard box. and so on. Any calendar may be used as long as it is made of paper and the calendar can be printed, such as a turning page and a desk calendar. The paper stationery can be any material as long as it is made of paper. For example, albums, carbon paper, silica paper, scrapbooks, sketchbooks, scorecards, scorebooks, books, notebooks, slips, copy paper, paper There are racing paper, notebook, stationery, envelope, graph paper, loose leaf, etc. Of course, the present invention is not limited to this, and it is made of paper.
[0014]
  Further, claim 2 of the present invention isThe printed matter according to claim 1, further comprising a base ink layer positioned between the substrate sheet and the varnish layer and laminated in any order with the information ink layer.It is.
[0015]
Therefore, according to the second aspect of the present invention, since the base ink layer is laminated on the substrate sheet in any order, the lottery is performed by applying strong light from the back surface of the substrate sheet. Even if the information is projected as a shadow on the outermost layer, it is possible to make it difficult to decipher the lottery information by the projected shadow, and the varnish layer is at least larger than the concealment layer, and the concealment layer Since it is provided so as to protrude from the outer periphery, even if a concealing layer that can be peeled off by an adhesive tape is applied, the concealing layer can be peeled off without causing paper peeling.
[0016]
That is, when the varnish layer according to claim 1 is provided so as to have at least an area larger than that of the masking layer and out of the outer periphery of the masking layer, the substrate sheet has a low surface strength. However, if paper with a certain thickness is not used, the lottery information concealed in the concealment layer becomes a shadow on the outermost layer when strong light is applied from the back side of the substrate sheet. The lottery information can be easily decoded as compared with the case where thin paper is used for the substrate sheet. For example, if the lottery information that is concealed may be read illegally, such as a lottery for an appendix of a magazine for the lower grades of elementary school, it is not so important. This is an important issue for lotteries involving money. In a lottery such as a lottery ticket, if a fraudulent act of pre-reading the concealed lottery information becomes possible by applying strong light from the back side of the substrate sheet, it will be extraordinary confusion. Will be invited. Therefore, if the lottery information that is concealed has a significant value, such as a lottery that wins a lottery or a luxury prize, the lottery will be created by the invention according to claim 1 of the present application. For example, the paper used for the substrate sheet must have a certain thickness. For example, it is difficult to employ a very thin paper having a low surface strength as a substrate sheet, which is called fine coated paper in gravure printing. However, when thick paper is used for the substrate sheet, it is difficult to process into a signature because the paper is thick, and even if it can be processed into a signature, the thickness per magazine increases and operation costs increase. The finished printed matter is in the form of a sheet or card due to reasons such as If these sheet-like or card-like printed materials are to be bound into a booklet, a new process is required, which has been a factor in increasing manufacturing costs.
[0017]
According to the second aspect of the present invention, it is possible to employ thin paper for the substrate sheet by the information ink layer and the base ink layer laminated in an arbitrary order. This is because even if the base ink layer shines strong light from the back surface of the substrate sheet and projects the lottery information as a shadow on the outermost layer, it makes it difficult to decipher the lottery information by the shadow. Here, the base ink layer may be a character, a symbol, a figure, or a combination thereof, or may be solid. Any color may be used as the color used for the base ink layer as long as it can be distinguished from the lottery information. Furthermore, a color picture may be used. Moreover, since at least one part should just overlap with an information ink layer, you may provide a base | substrate ink layer in the whole substrate sheet, for example. Here, overlapping means that, for example, when a base ink layer and an information ink layer are provided by a printing method, at least a part of the printed portions forming the respective layers overlap. Note that the base ink layer plays a role of making it difficult to decipher the lottery information due to the projected shadow even if the lottery information is projected as a shadow on the outermost layer by applying strong light from the back surface of the substrate sheet. Therefore, even if it does not overlap with the information ink layer, it is not necessary to overlap if it can play this role.
[0018]
For example, if the background ink layer is a pattern, the lottery information is projected as a shadow on the concealment layer, which is the outermost layer, by shining strong light from the back side of the substrate sheet, and the lottery information is read by the projected shadow. Since the pattern of the ink layer also creates a shadow on the concealment layer, it becomes more difficult to recognize only the shadow of the lottery information.
[0019]
In addition, when the base ink layer is solid, the lottery information is projected as a shadow on the concealment layer, which is the outermost layer, by shining strong light from the back side of the substrate sheet, and the lottery information is read by the projected shadow. Since light is further blocked by the ink layer, it is possible to make it more difficult to project the shadow of the lottery information to the concealment layer that is the outermost layer.
[0023]
Therefore, according to claim 2 of the present invention, even if a thin paper sheet with low surface strength is used for the substrate sheet and a concealing layer that can be peeled off by an adhesive tape is applied, the concealing layer is peeled off without causing paper peeling. Further, it is possible to provide a printed matter that can make it difficult to decipher the lottery information even if the lottery information is projected as a shadow on the outermost layer by applying strong light from the back surface of the substrate sheet.
[0024]
In addition, since thin paper can be used for the substrate sheet, a lottery or the like according to the present invention can be a part of the signature. That is, after a lottery or the like is provided at an arbitrary place on the paper according to the present invention, it can be processed into a signature in a normal process. As a result, a booklet having a lottery portion can be manufactured in a normal bookbinding process, and the manufacturing cost can be reduced as compared with the case where a booklet is manufactured using thick paper. Therefore, unlike the case where thick paper that cannot be used as a signature is employed, it is not necessary to provide a new process, and the manufacturing cost can be reduced.
[0025]
In addition, if thin paper is used for the substrate sheet, the substrate sheet can be easily folded after each layer is applied, so it is possible to provide a concealing layer that can be peeled off with adhesive tape even on folded items such as flyers. It becomes. Therefore, for example, it is possible to provide a concealing layer that can be peeled off with an adhesive tape on a newspaper leaflet, a pamphlet, or the like, thereby improving the advertising effect.
[0026]
In addition, it is possible to provide a concealing layer that can be peeled off by an adhesive tape on gift wrapping paper or a paper bag that stores products at the time of purchase at the store, and this makes it possible to improve purchase motivation.
[0027]
Even with the invention according to claim 1, lottery information such as a lottery for a magazine for the elementary school lower grades or a type of lottery for giving gifts to all applicants. If there is no lottery or the like, it is a matter of course that thin paper with low surface strength can be used for the substrate sheet. According to the first aspect of the present invention, if a lottery or the like in which the lottery information does not have so much value is created, the number of steps is further reduced, so that the manufacturing cost can be minimized. Here, the thick paper is a paper in which the lottery information cannot be read illegally even when a strong light is applied from the back surface of the substrate sheet when the printed matter according to the invention of claim 1 is created. In other words, paper having a basis weight of 150 gm or more corresponds to thick paper. Depending on the type of paper, if the thickness is 2 μm or more, the lottery information can be read illegally even when a strong light is applied from the back side of the substrate sheet when the printed matter according to the invention of claim 1 is created. It is considered impossible. Further, the thin paper is a paper in which the lottery information can be read illegally even when a strong light is applied from the back surface of the substrate sheet when the printed matter according to the invention of claim 1 is created. For example, paper having a basis weight smaller than 150 square meters corresponds to thin paper.
[0028]
Alternatively, a thin paper may be adopted as the substrate sheet, and a card-like or sheet-like thing having a concealing layer that can be peeled off by an adhesive tape may be created. For example, when a game card is created, if a thin paper is used for the substrate sheet, it is possible to make it easier to carry.
[0029]
Furthermore, since thin paper can be used for the substrate sheet, it is possible to reduce material costs and save resources when using thin paper than when using thick paper. Become. Needless to say, the amount of garbage can be reduced as compared with the case of using thick paper.
[0030]
  Further, claim 3 of the present invention isThe printed matter according to claim 1, further comprising an ink layer which is located between the varnish layer and the masking layer and is provided so as to be peelable together with the masking layer.
[0031]
Therefore, according to claim 3 of the present invention, since the ink layer that can be peeled off together with the concealing layer is provided on the varnish layer, the lottery information is shaded on the outermost layer by applying strong light from the back surface of the substrate sheet. It is possible to make it difficult to decipher the lottery information using the projected shadow, and the varnish layer is at least larger than the concealment layer and out of the outer periphery of the concealment layer. Therefore, even if a concealing layer that can be peeled off with an adhesive tape is applied, it is possible to peel off the concealing layer without causing paper peeling.
[0032]
That is, when the varnish layer according to claim 1 is provided so as to have at least an area larger than that of the masking layer and out of the outer periphery of the masking layer, the substrate sheet has a low surface strength. However, if paper with a certain thickness is not used, the lottery information concealed in the concealment layer becomes a shadow on the outermost layer when strong light is applied from the back side of the substrate sheet. The lottery information can be easily decoded as compared with the case where thin paper is used for the substrate sheet. For example, if the lottery information that is concealed may be read illegally, such as a lottery for an appendix of a magazine for the lower grades of elementary school, it is not so important. This is an important issue for lotteries involving money. In a lottery such as a lottery ticket, if a fraudulent act of pre-reading the concealed lottery information becomes possible by applying strong light from the back side of the substrate sheet, it will be extraordinary confusion. Will be invited. Therefore, if the lottery information that is concealed has significant value, such as a lottery or a lottery prize, etc., the lottery will be created by the invention of claim 1 of the present application. The paper used for the substrate sheet must have a certain thickness. For example, it is difficult to employ a very thin paper having a low surface strength as a substrate sheet, which is called fine coated paper in gravure printing. However, when thick paper is used for the substrate sheet, it is difficult to process into a signature because the paper is thick, and even if it can be processed into a signature, the thickness per magazine increases and operation costs increase. The finished printed matter is in the form of a sheet or card due to reasons such as If these sheet-like or card-like printed materials are to be bound into a booklet, a new process is required, which has been a factor in increasing manufacturing costs.
[0033]
In claim 3, this problem can be solved by the ink layer laminated on the varnish layer. This is because the ink layer plays a role of making it difficult to decipher the lottery information by the projected shadow even if the lottery information is projected as a shadow on the outermost layer by applying strong light from the back surface of the substrate sheet. Here, the ink layer may be a character, a figure, a symbol, a combination thereof, or a solid coating. In addition, the color used for the ink layer is preferably the same color as the information ink layer or a dark color, but is not limited thereto, and may be any color. For example, silver ink that is often used for the masking layer may be used for the ink layer, or a color pattern may be used. Moreover, since at least one part should just overlap with the information ink layer located under a varnish layer, for example, you may provide an ink layer in the whole substrate sheet. Here, overlapping means that, for example, when an ink layer and an information ink layer are provided by a printing method, at least a part of printing portions forming the respective layers overlap. Note that the ink layer plays a role of making it difficult to decipher the lottery information by the projected shadow even if the lottery information is projected as a shadow on the outermost layer by applying strong light from the back surface of the substrate sheet. Even if it does not overlap with the information ink layer, there is no need to overlap if it can play this role.
[0034]
For example, when the ink layer is a pattern, the lottery information is projected as a shadow on the concealment layer that is the outermost layer by shining strong light from the back side of the substrate sheet, and the lottery information is read by the projected shadow. Since this pattern also creates a shadow on the concealment layer, it is possible to make it more difficult to recognize only the shadow of the lottery information.
[0035]
In addition, when the ink layer is solid, the lottery information is projected as a shadow on the outermost concealing layer by shining strong light from the back side of the substrate sheet, and the ink layer is read even if the lottery information is read by the projected shadow. Therefore, it is possible to make it more difficult to project the shadow of the lottery information to the outermost concealment layer.
[0036]
In addition, if the ink layer is marked with a note such as “Please remove with an adhesive tape” or “Please remove here”, it can alert the user and prevent incorrect usage. It becomes.
[0037]
Furthermore, when the ink layer is made of characters, figures, symbols, or a combination thereof, a picture provided like a Japanese paper watermark can be seen, so that the aesthetics can be improved.
[0038]
Here, when the ink layer is made of characters, symbols, graphics, or a combination thereof, it is desirable that the information ink layer be concealed by the ink layer if it is made white. However, the present invention is not limited to this.
[0039]
  Therefore, according to claim 3 of the present invention, even if a thin paper sheet with low surface strength is used for the substrate sheet and a concealing layer that can be peeled off with an adhesive tape is applied, the concealing layer is peeled off without causing paper peeling. Further, it is possible to provide a printed matter that can make it difficult to decipher the lottery information even if the lottery information is projected as a shadow on the outermost layer by applying strong light from the back surface of the substrate sheet.
[0040]
  In addition, since thin paper can be used for the substrate sheet, a lottery or the like according to the present invention can be a part of the signature. That is, after a lottery or the like is provided at an arbitrary place on the paper according to the present invention, it can be processed into a signature in a normal process. As a result, a booklet having a lottery portion can be manufactured in a normal bookbinding process, and the manufacturing cost can be reduced as compared with the case where a booklet is manufactured using thick paper. Therefore, unlike the case where thick paper that cannot be used as a signature is employed, it is not necessary to provide a new process, and the manufacturing cost can be reduced.
[0041]
  In addition, if thin paper is used for the substrate sheet, the substrate sheet can be easily folded after each layer is applied, so it is possible to provide a concealing layer that can be peeled off with adhesive tape even on folded items such as flyers. It becomes. Therefore, for example, it is possible to provide a concealing layer that can be peeled off with an adhesive tape on a newspaper leaflet, a pamphlet, or the like, thereby improving the advertising effect.
[0042]
  Further, by providing a concealing layer that can be peeled off with an adhesive tape on gift wrapping paper or a paper bag for storing products at the time of purchase, it is possible to improve the willingness to purchase.
[0043]
  Even with the invention according to claim 1, lottery information such as a lottery for a magazine for the elementary school lower grades or a type of lottery for giving gifts to all applicants. If there is no lottery or the like, it is a matter of course that thin paper with low surface strength can be used for the substrate sheet. According to the first aspect of the present invention, if a lottery or the like in which the lottery information does not have so much value is created, the number of steps is further reduced, so that the manufacturing cost can be minimized. Here, the thick paper is a paper in which the lottery information cannot be read illegally even when a strong light is applied from the back surface of the substrate sheet when the printed matter according to the invention of claim 1 is created. In other words, paper having a basis weight of 150 gm or more corresponds to thick paper. Depending on the type of paper, if the thickness is 2 μm or more, the lottery information can be read illegally even when a strong light is applied from the back side of the substrate sheet when the printed matter according to the invention of claim 1 is created. It is considered impossible. Further, the thin paper is a paper in which the lottery information can be read illegally even when a strong light is applied from the back surface of the substrate sheet when the printed matter according to the invention of claim 1 is created. For example, paper having a basis weight smaller than 150 square meters corresponds to thin paper.
[0044]
  Alternatively, a thin paper may be adopted as the substrate sheet, and a card-like or sheet-like thing having a concealing layer that can be peeled off by an adhesive tape may be created. For example, when a game card is created, if a thin paper is used for the substrate sheet, it is possible to make it easier to carry.
[0045]
  Furthermore, since thin paper can be used for the substrate sheet, it is possible to reduce material costs and save resources when using thin paper than when using thick paper. Become. Needless to say, the amount of garbage can be reduced as compared with the case of using thick paper.
[0046]
  According to a fourth aspect of the present invention, the ink layer has a fake lottery information that is lottery information other than the lottery information included in the information ink layer.
[0047]
  Therefore, according to claim 4 of the present invention, since the ink layer has the fake lottery information, it is more difficult to decipher the lottery information even if it tries to read the lottery information illegally by applying strong light from the back side of the substrate sheet. Can be. Here, the fraudulent lottery information is lottery information other than the lottery information included in the information ink layer, for example, information having the opposite meaning to the lottery information included in the information ink layer. For example, if the information ink layer is a character corresponding to the winning, if the ink layer is a character corresponding to the defeat so that it overlaps with the information ink layer, the lottery information is displayed by applying strong light from the back of the substrate sheet. Even if it is projected as a shadow on the outermost layer, the projected shadow is a combination of the character corresponding to the win and the character corresponding to the defeat. It is difficult to determine what is written because the letters overlap, and even if you understand that the letters that mean winning and the letters that mean lost are overlapped, It is very difficult to judge whether the information ink layer has a letter meaning winning or a letter meaning winning.
[0048]
  The ink layer is provided so as to be peelable from the varnish layer, and the concealing layer is provided so as to be peeled off together with the varnish layer. The ink layer is peeled off together with the hiding layer by the adhesive tape. Therefore, only the lottery information can be visually observed after the masking layer is peeled off.
[0049]
  Therefore, according to claim 4 of the present invention, even if a thin paper with low surface strength is used for the substrate sheet and a concealing layer that can be peeled off with an adhesive tape is applied, the concealing layer is peeled off without causing paper peeling. Further, it is possible to provide a printed matter that can make it difficult to decipher the lottery information even if the lottery information is projected as a shadow on the outermost layer by applying strong light from the back surface of the substrate sheet.
[0051]
  Further, the claims of the present invention5IsThe printed matter according to any one of claims 1 to 4, further comprising an ink layer that is disposed on the masking layer and is detachable together with the masking layer.
[0052]
  Accordingly, the claims of the present invention5According to the above, since the ink layer that can be peeled off together with the concealing layer is provided on the concealing layer, even if the lottery information is projected as a shadow on the outermost layer by applying strong light from the back surface of the substrate sheet, it is copied. It is possible to make it difficult to decipher lottery information by shadows, and furthermore, since the varnish layer is provided so as to have at least an area larger than the hiding layer and out of the outer circumference of the hiding layer, the adhesive tape Even if a peelable masking layer is applied, it is possible to peel the masking layer without causing paper peeling.
[0053]
That is, when the varnish layer according to claim 1 is provided so as to have at least an area larger than that of the masking layer and out of the outer periphery of the masking layer, the substrate sheet has a low surface strength. However, if paper with a certain thickness is not used, the lottery information concealed in the concealment layer becomes a shadow on the outermost layer when strong light is applied from the back side of the substrate sheet. The lottery information can be easily decoded as compared with the case where thin paper is used for the substrate sheet. For example, if the lottery information that is concealed may be read illegally, such as a lottery for an appendix of a magazine for the lower grades of elementary school, it is not so important. This is an important issue for lotteries involving money. In a lottery such as a lottery ticket, if a fraudulent act of pre-reading the concealed lottery information becomes possible by applying strong light from the back side of the substrate sheet, it will be extraordinary confusion. Will be invited. Therefore, if the lottery information that is concealed has significant value, such as a lottery or a lottery prize, etc., the lottery will be created by the invention of claim 1 of the present application. The paper used for the substrate sheet must have a certain thickness. For example, it is difficult to employ a very thin paper having a low surface strength as a substrate sheet, which is called fine coated paper in gravure printing. However, when thick paper is used for the substrate sheet, it is difficult to process into a signature because the paper is thick, and even if it can be processed into a signature, the thickness per magazine increases and operation costs increase. The finished printed matter is in the form of a sheet or card due to reasons such as If these sheet-like or card-like printed materials are to be bound into a booklet, a new process is required, which has been a factor in increasing manufacturing costs.
[0054]
  Claim5Then, this problem can be solved by an ink layer that is detachably laminated on the masking layer. This is because the ink layer plays a role of making it difficult to decipher the lottery information due to the projected shadow even if the lottery information is projected as a shadow on the outermost layer by applying strong light from the back surface of the substrate sheet. Here, the ink layer may be characters, figures, symbols, or a combination thereof, or may be solid. The color used for the ink layer is preferably the same color as the information ink layer or a dark color, but is not limited to these and may be any color. For example, silver ink that is often used for the masking layer may be used for the ink layer, or a color pattern may be used. Moreover, since at least one part should just overlap with the information ink layer located under a varnish layer, for example, you may provide an ink layer in the whole substrate sheet. Here, overlapping means that, for example, when an ink layer and an information ink layer are provided by a printing method, at least a part of printing portions forming the respective layers overlap. Note that the ink layer plays a role of making it difficult to decipher the lottery information by the projected shadow even if the lottery information is projected as a shadow on the outermost layer by applying strong light from the back surface of the substrate sheet. Even if it does not overlap with the information ink layer, there is no need to overlap if it can play this role.
[0055]
For example, if the ink layer is a pattern, the lottery information is projected as a shadow on the outermost ink layer by shining strong light from the back side of the substrate sheet, and the lottery information is decoded by the projected shadow. This makes it more difficult to recognize only the shadow of the lottery information.
[0056]
In addition, if the ink layer is solid black, even if you shine strong light from the back side of the substrate sheet, copy the lottery information as a shadow on the outermost ink layer, and try to decode the lottery information with the projected shadow, It becomes possible to make it more difficult to recognize the shadow by the ink layer.
[0057]
In addition, if the ink layer is marked with a note such as “Please remove with adhesive tape” or “Please remove here”, it can alert the user and prevent incorrect usage. It becomes.
[0058]
Further, when the ink layer is made of characters, figures, symbols, or a combination thereof, a concealing layer can be seen between these characters and the like, and the aesthetic appearance can be improved.
[0059]
For example, if the masking layer is made of silver ink and the ink layer has a star-shaped pattern, the silver ink of the masking layer can be seen from the star-shaped part of the star, improving the appearance and improving the masking layer. It can be used more effectively.
[0060]
Here, when the ink layer is made of characters, symbols, graphics, or a combination thereof, it is desirable that the information ink layer be concealed by the ink layer if it is made white. However, the present invention is not limited to this.
[0064]
  Accordingly, the claims of the present invention5According to the present invention, even when a thin paper sheet with low surface strength is used for the substrate sheet and a concealing layer that can be peeled off by an adhesive tape is applied, the concealing layer can be peeled off without causing paper peeling. It is possible to provide a printed matter that makes it difficult to decipher the lottery information even if the lottery information is projected as a shadow on the outermost layer by shining strong light from the back side.
[0065]
In addition, since thin paper can be used for the substrate sheet, a lottery or the like according to the present invention can be a part of the signature. That is, after a lottery or the like is provided at an arbitrary place on the paper according to the present invention, it can be processed into a signature in a normal process. As a result, a booklet having a lottery portion can be manufactured in a normal bookbinding process, and the manufacturing cost can be reduced as compared with the case where a booklet is manufactured using thick paper. Therefore, unlike the case where thick paper that cannot be used as a signature is employed, it is not necessary to provide a new process, and the manufacturing cost can be reduced.
[0066]
In addition, if thin paper is used for the substrate sheet, the substrate sheet can be easily folded after each layer is applied, so it is possible to provide a concealing layer that can be peeled off with adhesive tape even on folded items such as flyers. It becomes. Therefore, for example, it is possible to provide a concealing layer that can be peeled off with an adhesive tape on a newspaper leaflet, a pamphlet, or the like, thereby improving the advertising effect.
[0067]
Further, by providing a concealing layer that can be peeled off with an adhesive tape on gift wrapping paper or a paper bag for storing products at the time of purchase, it is possible to improve the willingness to purchase.
[0068]
Even with the invention according to claim 1, lottery information such as a lottery for a magazine for the elementary school lower grades or a type of lottery for giving gifts to all applicants. If there is no lottery or the like, it is a matter of course that thin paper with low surface strength can be used for the substrate sheet. According to the first aspect of the present invention, if a lottery or the like in which the lottery information does not have so much value is created, the number of steps is further reduced, so that the manufacturing cost can be minimized. Here, the thick paper is a paper in which the lottery information cannot be read illegally even when a strong light is applied from the back surface of the substrate sheet when the printed matter according to the invention of claim 1 is created. In other words, paper having a basis weight of 150 gm or more corresponds to thick paper. Depending on the type of paper, if the thickness is 2 μm or more, the lottery information can be read illegally even when a strong light is applied from the back side of the substrate sheet when the printed matter according to the invention of claim 1 is created. It is considered impossible. Further, the thin paper is a paper in which the lottery information can be read illegally even when a strong light is applied from the back surface of the substrate sheet when the printed matter according to the invention of claim 1 is created. For example, paper having a basis weight smaller than 150 square meters corresponds to thin paper.
[0069]
Alternatively, a thin paper may be adopted as the substrate sheet, and a card-like or sheet-like thing having a concealing layer that can be peeled off by an adhesive tape may be created. For example, when a game card is created, if a thin paper is used for the substrate sheet, it is possible to make it easier to carry.
[0070]
Furthermore, since thin paper can be used for the substrate sheet, it is possible to reduce material costs and save resources when using thin paper than when using thick paper. Become. Needless to say, the amount of garbage can be reduced as compared with the case of using thick paper.
[0075]
  Further, claim 6 of the present invention isThe printed matter according to any one of claims 1 to 5, wherein the lottery information is formed of halftone dots having a halftone dot area ratio of approximately 30% or less.It is.
[0076]
That is, according to claim 6 of the present invention, since lottery information is provided with halftone dots having a halftone dot area ratio of approximately 30% or less, even if strong light is applied from the back surface of the substrate sheet, the lottery information is used as a shadow. It can be difficult to copy.
[0077]
Here, approximately 30% or less is preferably 30% or less, but it is approximately 30% or less including errors such as the degree of ink at the time of printing.
[0078]
A seventh aspect of the present invention is a booklet having the printed matter according to any one of the first to sixth aspects.
[0079]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1A is a top view showing a printed matter of the present invention, and FIG. 1B is a cross-sectional view taken along a dotted line a-a in FIG. In FIG. 1, 1 is a lottery card which is a printed matter, 2 is a substrate sheet, 3 is a lottery portion having information of “around” or “out”, 4 is an information ink layer, 5 is a varnish layer, 6 is a concealing layer, 7 Is a difference in radius between the varnish layer and the concealing layer, 8 is a finding portion which is a pattern portion, and 9 is an explanation portion which is a pattern portion.
[0080]
In FIG. 1, the lottery card 1 has a card shape, and is formed by providing a lottery part 3, a finding part 8 that is a picture part, and an explanation part 9 that is a picture part on a substrate sheet 2. . The lottery portion 3 is composed of an information ink layer 4, a varnish layer 5, and a concealing layer 6, and has lottery information “win” or “out”. In the present embodiment, the lottery portion 3 is within the lower half range when the substrate sheet 2 is divided into two equal parts, and the left and right intervals between the lottery portion 3 and the lottery portion 3 are equal and the top and bottom are In order to make sure, there are 6 rows in 3 rows, 6 in total. Also, the dimensions from the both ends of the substrate sheet 2 and the ground side to the center of the lottery portion 3 are determined so that the lottery portion 3 does not protrude from both ends of the substrate sheet 2 and the ground side. It is set to be the same as or larger than the maximum value of the dimension up to the end of the portion 3.
[0081]
The information ink layer 4 constituting the lottery part 3 is a layer that forms a “hit” or “out of”. The varnish layer 5 is located between the information ink layer 4 and the masking layer 6 and covers the information ink layer 4. The masking layer 6 is positioned on the varnish layer 5 and is covered with the information ink layer. 4 is a layer covering 4. Both the varnish layer 5 and the concealing layer 6 have a circular shape, and the centers of the varnish layer 5 and the concealing layer 6 are provided so as to overlap the center of the lottery portion 3. Further, the area of the varnish layer 5 is larger than that of the masking layer 6, and the varnish layer 5 is provided so as to come out of the masking layer 6 evenly. The portion where the varnish layer 5 protrudes from the concealing layer 6 prevents the adhesive tape from being attached to the substrate sheet 2 when it is peeled off. The dimension of the portion where the varnish layer 5 protrudes from the masking layer 6 varies depending on the size of the masking layer 6 or the size (length, width) of the adhesive tape used. If the adhesive tape used to peel off the masking layer 6 is a roll of a rectangular tape, such as a commercially available tape, the width of the tape is cut to an appropriate size. Let x be x. Further, let us consider a case where the diameter of the masking layer 6 is y, the diameter of the varnish layer 5 is z, and the edge of the adhesive tape is covered with the arc of the masking layer 6 when the masking layer 6 is peeled off. Here, the length of the adhesive tape does not matter because there is a portion held by hand, but the length of the portion attached to the concealing layer 6 is the diameter of the concealing layer 6. When the diameter (x) of the masking layer 6 is larger than the width (y) of the adhesive tape (that is, when x> y), the adhesive tape having a length of several 1 comes out from the outer periphery of the masking layer 6. Therefore, it is necessary to provide the varnish layer 5 so that the diameter of the varnish layer 5 is at least 2 and the area of the varnish layer 5 is larger than that of the masking layer 6, and the length of Formula 1 is longer than the outer periphery of the masking layer 6.
[0082]
[Expression 1]

[0083]
[Expression 2]

[0084]
Further, when the diameter (x) of the masking layer 6 is the same as the width (y) of the adhesive tape (that is, when x = y), the adhesive tape having a length of several 3 comes out from the outer periphery of the masking layer. Therefore, it is necessary to provide the varnish layer 5 so that the diameter of the varnish layer 5 is at least 4 and the area of the varnish layer 5 is larger than that of the masking layer 6, and the length of Formula 1 is longer than the outer periphery of the masking layer 6.
[0085]
[Equation 3]

[0086]
[Expression 4]

[0087]
Further, when the diameter (x) of the masking layer 6 is smaller than the width (y) of the adhesive tape (that is, when x <y), the adhesive tape having a length of 5 is longer than the outer periphery of the masking layer 6. Therefore, it is necessary to provide the varnish layer 5 so that at least the diameter of the varnish layer 5 is larger than that of the masking layer 6 and the length of Formula 1 is longer than the outer periphery of the masking layer 6.
[0088]
[Equation 5]

[0089]
[Formula 6]

[0090]
These are the minimum dimensions that the varnish layer 5 comes out from the masking layer 6. If the varnish layer 5 is provided so that the varnish layer 5 comes out from the masking layer 6 at this dimension, the raw material of the varnish layer 5 can be minimized, and the manufacturing cost is reduced. Can be suppressed. However, the present invention is not limited to this. In the present embodiment, the varnish layer 5 and the concealing layer 6 are both circular. However, the present invention is not limited to this, and the adhesive tape is prevented from sticking to the substrate sheet 2 when the concealing layer 6 is peeled off. Any shape can be used as long as it is possible.
[0091]
In addition, the lottery portion is set so that only one of the six lotteries is a “hit” and the rest is “out of”. The appearance of the winning lottery portion having the information “spot” is the same as that of the winning lottery portion having the information “out”. Therefore, in a normal state, it is impossible to determine which lottery part is “winning” and which lottery part is “out of”. The person who uses the lottery card must select one of the six lottery parts and peel off the concealment layer of the selected lottery part with adhesive tape. You can know if it is “out of”. In this embodiment, the lottery information is provided as “winning” if “winning” and “lost” if “out”, but it is not necessary to limit to this. The lottery information may be information other than “winning” and “losing” information, for example, a bingo game number, or information that provides information corresponding to “answer” for children's learning.
[0092]
In order to manufacture the lottery card 1, first, on the base sheet 2, the finding portion 8 that is a pattern portion and the caution portion 9 that is a pattern portion are applied by a gravure printing method at a position that does not overlap with the information ink layer, Next, an information ink layer is applied on the substrate sheet by a gravure printing method, and then the varnish layer is gravure so as to cover the information ink layer and on the substrate sheet on which nothing has been printed yet. It is applied by a printing method, and then a concealing layer is applied by a gravure printing method.
[0093]
The method for forming each layer will be described in more detail. The information ink layer is provided using rosin resin ink. In this embodiment, rosin resin ink is used, but it is not necessary to limit to this. Ink used in normal gravure printing can be used. The halftone dot area ratio is set to be approximately 30%. By providing the dot area ratio of the information ink layer to be approximately 30% or less, it is possible to prevent the lottery information from being read illegally by applying strong light from the back surface of the substrate sheet. That is, according to the applicant's experiment, when an information ink layer is provided with a dot area ratio of 10%, lottery information does not appear as a shadow on the concealment layer even when strong light is applied from the back side. Since the lottery information is thin when peeled off, the lottery information cannot be read without staring. When the halftone dot area ratio is set to 20% and 30%, strong light is emitted from the back side. The lottery information does not appear as a shadow on the concealment layer even if it hits, and even when the concealment layer is peeled off, the lottery information can be easily read, and when the halftone dot area ratio is set to 40%, The result was that lottery information would appear as a shadow when exposed to strong light from the back. Therefore, it is more preferable that the halftone dot area ratio is 20% to 30%.
[0094]
The varnish layer is provided by using a chlorinated rubber resin varnish ink, and the concealing layer is a nitrocellulose resin silver ink. When the varnish layer and the masking layer are peeled off with an adhesive tape, it is necessary to select a resin having a reciprocity as the resin forming each layer so that the varnish layer and the masking layer are peeled off between the varnish layer and the masking layer. There is. In this embodiment, the chlorinated rubber resin used for the varnish layer and the nitrocellulose resin used for the masking layer have reciprocity, and the masking layer exhibits low adhesion and low adhesion to the varnish layer. Therefore, by sticking and peeling the adhesive tape on the concealing layer, it is possible to peel between the concealing layer and the varnish layer and peel off only the concealing layer. In addition to the chlorinated rubber resin, vinyl chloride monoacetate copolymer resin or the like can be used for the varnish layer. In addition to the nitrocellulose resin, a polyamide resin, an acrylic resin, or the like can be used for the masking layer. In this embodiment, the varnish layer is transparent. However, as long as the information ink layer can be visually observed, the varnish layer may be translucent or may be colored by mixing a color material. However, when coloring, care must be taken not only to make the information ink layer visible but also to have sufficient reciprocity with the hiding layer. In this embodiment, the concealing layer is a silver ink of a nitrocellulose resin. However, the concealing layer is not limited to this, and indigo ink or black ink may be employed as long as the information ink layer can be concealed. When adopting a color other than silver ink, it is preferable to provide it so that the density is higher than that of the information ink layer because the information ink layer can be more concealed.
[0095]
In addition to the lottery part, it is also possible to provide a picture part if it is not attached to the information ink layer. In the present embodiment, only the finding part 8 that is the pattern part and the caution writing part 9 that is the pattern part are provided in addition to the lottery part. You may provide a symbol, a figure, or these combination. In the present embodiment, the order in which the pattern portion is provided and then the lottery portion is employed, but the order in which the lottery portion is provided and then the pattern portion is provided may be employed. In the present embodiment, the reason for adopting the method of first laminating the lottery part in order after first providing the pattern part is to prevent the concealment layer from being damaged. It is possible to adopt the method described later, which is to provide the pattern portion after the lottery portion is provided, but if the method described later is employed, the concealing layer is applied in the manufacturing process and then the pattern portion is applied again. As a result, the roller passes over the already-provided concealing layer, so that the concealing layer may be damaged. If the concealment layer is scratched, it not only impairs the beauty, but the lottery information concealed from the gap between the scratches may become visible. Since the masking layer of the present invention cannot be peeled off without using an adhesive tape and the masking layer is very strong, it is unlikely that the masking layer will be damaged by adopting the latter method. Is not a very preferred method. However, in reality, this is a selectable production method and can be used in the present invention. There is no need to limit the order to these steps. For example, the step of providing the pattern portion after the step of providing the information ink layer and the step of providing the varnish layer thereafter may be employed, and the order can be freely selected.
[0096]
In the present embodiment, offset printing is adopted as a printing method, but the printing method is not limited to this, and other means may be used as long as application is possible. For example, other printing methods such as offset and silk screen may be employed, and roller partial coating, brush coating, etc. may be employed as methods other than the printing method. In this embodiment, all layers are formed by a gravure printing method, but it is not necessary to limit to this. Any means may be adopted as a means for providing each layer as long as it can be applied. For example, if a silk screen printing method is used to provide a concealing layer, the concealing layer can be thickened, so that the concealing action can be improved, and a gravure printing method can be used to provide an information ink layer. For example, the unevenness of the information ink layer that can be formed as a concealing layer can be made inconspicuous. However, if various printing methods are mixed to form each layer, the process becomes complicated and the manufacturing cost increases, so care must be taken. In the present invention, since all layers can be consistently formed by a certain printing method as in the present embodiment, the manufacturing cost can be minimized. The case where the gravure printing method is adopted and formed consistently is as described above. A case in which the offset printing method is adopted and consistently formed will be described. In the case of the offset printing method, the varnish used for normal offset printing is used for the varnish layer, and UV curable ink is used for the layers other than the varnish layer (information ink layer, concealment layer) to conceal the varnish layer. It becomes possible to give reciprocity between the layers. A method of consistently creating by adopting an offset printing method is disclosed in Japanese Patent No. 2711772 by the present applicant. The case where the screen printing method is adopted is the same as the case where the gravure printing method is adopted, and thus the description is omitted.
[0097]
As the material of the substrate sheet, for example, art paper, coated paper, high quality paper, medium quality paper, art post paper, matte coated paper, lightweight coated paper, pure white roll paper, fine coated fine paper as fine coated paper Paper, finely coated printed paper 1, finely coated printed paper 2, finely coated printed paper 3, paper used for printing coated paper, uncoated balls, ivory, double-sided cards, etc. as printing plates, or packaging Any paper such as kraft paper used for craft paper bags can be used for the substrate sheet. In addition, any basis weight can be adopted.
[0098]
Next, an example of the form of the varnish layer will be described with reference to FIG. In FIG. 2, the concealing layer 24 is made transparent so that the concealed information ink layer 17 is visible, but this is for the sake of clarity of the figure. Since it is hidden by 24, it cannot be seen in a normal state.
[0099]
FIG. 2 is a top view of a lottery portion showing another embodiment. In FIG. 2, 16 is a lottery part, 17 is an information ink layer, 18 is a varnish layer, 19 is an overlapping part of the varnish layer 18 that overlaps the masking layer 24, and 20 is an outer periphery of the masking layer 24 of the varnish layer 18. The right protruding portion of the varnish layer protruding from the right side, 21 is the protruding left portion of the varnish layer protruding from the left side of the outer periphery of the masking layer 24 of the varnish layer 18, 22 is the short axis of the varnish layer, and 23 is the long axis of the varnish layer , 24 is a masking layer, 25 is an overlapping part of the masking layer 24 overlapping the varnish layer 18, 26 is a protruding part of the masking layer 24 protruding from the upper side of the outer periphery of the varnish layer 18, and 27 is The concealing layer 24 protrudes from the lower side of the outer periphery of the varnish layer 18, 28 is the diameter of the concealing layer, 29 is the center of the concealing layer 24, 30 is the tangent to the concealing layer, and 31 is the concealing layer 24. This is the point where the outer circumference and the major axis of the varnish layer 18 intersect.
[0100]
In FIG. 2, the lottery portion 16 is provided on a substrate sheet (not shown), and includes an information ink layer 17, a varnish layer 18, and a concealing layer 24. The varnish layer 18 has an elliptical shape, and includes an overlapping portion 19 that overlaps the concealing layer 24, a varnish layer right protruding portion 20 and a varnish layer left protruding portion 21 that are connected to the left and right of the overlapping portion 19. . The masking layer 24 has a circular shape, and has an overlapping portion 25 overlapping with the varnish layer 18, and a masking layer upper protruding portion 26 and a masking layer lower protruding portion 27 connected to the upper and lower sides of the overlapping portion 25. . The varnish layer 18 is set such that the long axis 23 is longer than the diameter 28 of the hiding layer, the short axis 22 is shorter than the diameter 28 of the hiding layer, and the area thereof is larger than the hiding layer 24. Further, the intersection of the short axis 22 and the long axis 23 of the varnish layer 18 is provided so as to overlap the center 29 of the masking layer 24. That is, in FIG. 2, the varnish layer 18 is provided so as to have a larger area than the hiding layer 24 and come out from a part of the outer periphery of the hiding layer 24, and the hiding layer 24 has a larger area than the varnish layer 18. FIG. 3 is a top view showing a lottery portion of a printed matter that is small and is provided so as to protrude from a part of the outer periphery of a varnish layer 18. More specifically, the varnish layer 18 has a larger area than the masking layer 24 and is provided so as to come out from the left and right sides of the outer periphery of the masking layer 24. Further, the concealing layer 24 is located on the varnish layer 18, has a smaller area than the varnish layer 18, and is provided so as to exit from the upper and lower sides of the outer periphery of the varnish layer 18. Here, the overlapping part 19 that overlaps with the masking layer 24 in the varnish layer 18 and the overlapping part 25 that overlaps with the varnish layer 18 in the masking layer 24 overlap vertically, and the information ink layer 17 It is provided on a substrate sheet (not shown) so as to fall within the range.
[0101]
FIG. 2 will be described in more detail. In FIG. 2, parts of the varnish layer 18 and the hiding layer 24 do not overlap each other. The masking layer 24 is not laminated on the varnish layer right protruding portion 20 protruding from the right side of the outer periphery of the masking layer 24 and the varnish layer left protruding portion 21 protruding from the left side of the masking layer 24. Further, in the concealing layer 24, the concealing layer upper projecting portion 26 protruding from the upper side of the outer periphery of the varnish layer 18 and the concealing layer lower projecting portion 27 protruding from the lower side of the varnish layer 18 are below the respective portions. The varnish layer 18 does not exist and is directly laminated on the substrate sheet. The shielding layer tangent 30 is cut at a point where a tangent drawn so as to be in contact with the shielding layer 24 at a point 31 where the outer periphery of the shielding layer 24 and the major axis of the varnish layer 18 intersect with the outer periphery of the varnish layer 18. If the width of the adhesive tape used to peel the portion 25 overlapping the varnish layer 18 of the masking layer 24 is not less than the length of the masking layer tangent 30, the substrate sheet is removed when the overlapping portion 25 is peeled off. Since the adhesive tape will stick to the surface, it cannot be used. Many household adhesive tapes have a width of 12 mm or 15 mm. Accordingly, the short axis 22 and the long axis of the varnish layer 18 have a larger area than the concealing layer 24 and the outer side of the concealing layer 24 so that the length of the concealing layer tangent 30 is 12 mm or more. It is preferable to set 23. In addition, it is desirable to set the overlapping portion 25 between the varnish layer 18 and the concealing layer 24 to such a size that two or more characters having a size of 0.35 mm or more can be provided. When peeling off the overlapping portion 25 between the varnish layer 18 and the masking layer 24, the tip of the adhesive tape is placed near the masking layer tangent 30 to either the varnish layer right protruding portion 20 or the varnish layer left protruding portion 21 as desired. Without covering the overlapping part of the varnish layer 18 and the concealing layer 24, pasting to the vicinity of the concealing layer tangent 30 in the protruding part of the varnish layer on the opposite side, and then peeling off without causing paper peeling The overlapping portion 25 between the varnish layer 18 and the masking layer 4 can be peeled off.
[0102]
When the overlapping portion 25 between the varnish layer 18 and the masking layer 24 is peeled off, the masking layer upper projecting portion 26 and the masking layer lower projecting portion 27 are directly laminated on the substrate sheet without the varnish layer 18 being present thereunder. ing. Therefore, the masking layer upper protruding portion 26 and the masking layer lower protruding portion 27 cannot be peeled off because the ink forming the masking layer 24 has soaked into the substrate sheet. If the cover layer upper protruding portion 26 and the cover layer lower protruding portion 27 are forcibly peeled off, the paper will be peeled off. This makes it difficult to restore what has been peeled off once. In other words, if there are multiple lottery parts in one lottery card, and one of the lottery parts is selected with adhesive tape and the concealment layer is peeled off, it is “displaced”. It is possible to prevent the fraud that the masking layer peeled off is returned to the original, and it looks as if only the “around” part is peeled off. Here, as a means for returning, various methods such as a method of pasting the masking layer once peeled off, a method of stripping all the masking layer, and a method of providing a masking layer again by a printing method or other means, etc. There is.
[0103]
When the masking layer 24 of the present embodiment is peeled off with an adhesive tape, the masking layer upper protruding portion 26 and the masking layer lower protruding portion 27 of the masking layer 24 remain in the substrate sheet. It must be returned so that there is no seam between the upper and lower concealing layer protrusions remaining on the surface. Since the surface of the original concealing layer 24 is smooth, if the original concealing layer 24 is not returned to the original state so as to be smooth with the upper and lower concealing layer protruding portions remaining on the substrate sheet, it is easily seen that an illegal act was performed at a glance. End up. Furthermore, even if an attempt is made to provide a concealing layer after peeling off the upper and lower concealing layer protrusions remaining on the substrate sheet, the remaining upper and lower concealing layer protrusions are strongly bound to the substrate sheet by the ink forming the concealing layer. If it is forcibly peeled off, it will be peeled off with the paper, and it will be very difficult to restore the part where the paper has been peeled off and then provide a new concealing layer. In a lottery with lots of lotteries, if the adhesive tape was peeled off, it was returned as if it had not been peeled off, and a "hit" was produced. There are quite a lot of fraudulent acts of peeling off lots of lots, and there are various countermeasures. In the present invention, not only thin paper can be used for the substrate sheet, but also such illegal acts can be prevented.
[0104]
The size of the protruding part 26 on the masking layer and the protruding part 27 on the masking layer is not limited, but the overlapping part 25 between the varnish layer 18 and the masking layer 24 to be peeled is large, and the protruding part 26 on the masking layer remaining on the substrate sheet. It is expected that the larger the concealing layer lower projecting portion 27 is, the more difficult it is to return it. However, even if a part of the varnish layer 18 protrudes from the masking layer 24, if the area of the masking layer 24 becomes larger than the varnish layer 18, an adhesive tape is accidentally applied to a portion where the varnish layer 18 is not provided. Therefore, the area of the varnish layer 18 needs to be larger than that of the masking layer 24.
[0105]
Further, an example in which FIG. 2 is applied will be described with reference to FIG. In FIG. 3, the concealing layer 56 is made transparent so that the concealed information ink layer 41 is visible, but this is for the sake of clarity of the drawing. In practice, the information ink layer 41 is not concealed. Since it is hidden by 56, it cannot be seen in a normal state.
[0106]
FIG. 3 is a top view of a lottery portion showing another embodiment. In FIG. 3, 40 is a lottery part, 41 is an information ink layer, 42 is a varnish layer, 43 is a left part of the varnish layer 42, 44 is a right part of the varnish layer 42, and 45 is a left part 43. , 46 is the left side of the right piece portion 44, 47 is the right side of the right piece portion 44, 48 is the upper side of the right piece portion 44, 49 is the lower side of the right piece portion 44, 50 is the midpoint of the connecting portion, and 51 is the left side. The horizontal axis of the arrow part which is the part, 52 is the vertical axis of the arrow part which is the left side part, 53 is the overlapping part of the varnish layer 42 overlapping the masking layer 56, and 54 is the masking layer 56 of the varnish layer 42. A varnish layer right protruding portion protruding from the right side of the outer periphery, 55 is a varnish layer left protruding portion of the varnish layer 42 protruding from the left side of the outer periphery of the masking layer 56, 56 is a masking layer, and 57 is a varnish of the masking layer 56. An overlapping portion 58 overlapping with the layer 42, 58 is outside the varnish layer 42 of the concealing layer 56. The upper left protruding portion of the masking layer protruding from the upper left side, 59 is the lower left protruding portion of the masking layer protruding from the lower left side of the outer periphery of the varnish layer 42 of the masking layer 56, 60 is the center of the masking layer 56, and 61 is the left masking layer. Tangent line, 62 is a caution note, 63 is a right sticking location indication line, and 64 is a left sticking location indication line.
[0107]
In FIG. 3, the lottery portion 40 is provided on a substrate sheet (not shown) and includes an information ink layer 41, a varnish layer 42, and a concealing layer 55. The information ink layer 41 is a layer that forms lottery information. In the present embodiment, the information ink layer 41 forms a “hit”. The varnish layer 42 is composed of a left piece portion 43 and a right piece portion 44, and the left piece portion 43 and the right piece portion 44 are always connected. In the present embodiment, the left piece portion 43 is in the form of an arrow that faces a direction symmetrical to the right piece portion 44, and the right piece portion 44 has a rectangular shape. The left side portion and the right side portion are connected by the right side 45 of the left piece portion 43 and the left side 46 of the right piece portion 44. Moreover, it connects so that the midpoint of each piece to connect may match. The masking layer 56 is a circle, and the center 60 of the masking layer 56 is substantially the middle point 50 of the connecting portion between the right side 45 of the left piece portion 43 of the varnish layer 42 and the left side 46 of the right piece portion 44 of the varnish layer 42. The concealing layer 56 and the varnish layer 42 are stacked one above the other. The varnish layer 42 is designed to have a larger area than the concealment layer 56 in a state where the left piece portion 43 and the right piece portion 44 are connected, and a part of the varnish layer 42 protrudes from the outer periphery of the concealment layer 56. Yes. Furthermore, the masking layer 56 has a smaller area than the varnish layer 42, and is provided so that a part of the masking layer 56 protrudes from the outer periphery of the varnish layer 42. That is, the right side portion 44 of the varnish layer 42 is formed so that the left side 46 of the right piece portion 44 and the right side 47 of the right piece portion 44 are not less than the length of the diameter of the concealing layer 56 and the upper side of the right piece portion 44. 48 and the lower side 49 of the right piece 44 are designed to be equal to or longer than the radius of the concealing layer 56, and the left side 43 of the varnish layer 42 extends from the vertex of the arrow to the midpoint of the connecting portion. Is the horizontal axis 51, and the vertical axis of the arrow is the vertical axis 52, the length of the vertical axis 52 is shorter than the diameter of the masking layer 56, and the length of the horizontal axis 51 is It is provided so as to be longer than the radius of the masking layer 56. Therefore, when viewed from the front, the right protruding portion 54 of the varnish layer protrudes unevenly from the outer periphery of the semicircle on the right side of the portion near the center 60 of the masking layer 56, and from the portion near the center 60 of the masking layer 56. The left protruding portion 55 of the varnish layer protrudes unevenly from a part of the outer periphery of the left semicircle. Therefore, since these left and right projecting portions 54 and 55 protrude from the concealing layer 56, the adhesive tape is used when peeling the overlapping portion 57 overlapping the varnish layer 42 of the concealing layer 56 by using this. It can prevent sticking to the substrate sheet. Further, when viewed from the front, the concealing layer 56 has a concealing layer upper left projecting portion 58 projecting to the upper left from the overlapping portion 57 overlapping the varnish layer 42 and a concealing layer lower left projecting from the overlapping portion 57 to the lower left. A protruding portion 59 protrudes from the varnish layer 42 and is directly laminated on the substrate sheet. Therefore, after peeling the overlapping portion 57 overlapping the varnish layer 42 in the masking layer 56, the left and upper protruding portions 58 and 59, which are a part of the masking layer 56, remain. It is possible to prevent an illegal act of returning to Here, the overlapping part 53 that overlaps with the masking layer 56 in the varnish layer 42 and the overlapping part 57 that overlaps with the varnish layer 42 in the masking layer 56 overlap vertically, and the information ink layer 41 has the overlapping part. It is provided on a substrate sheet (not shown) within the range.
[0108]
It should be noted that it is preferable to design the overlapping portions 52 and 57 where the varnish layer 42 and the concealing layer overlap so that two or more characters having a size of 0.35 mm or more can be provided. Nor. Furthermore, it is preferable to design the varnish layer 42 and the masking layer 56 so that the width of the adhesive tape used for peeling is equal to or less than the length of the masking layer tangent 61. Further, even if a part of the varnish layer 42 protrudes from the masking layer 56, if the area of the masking layer 56 becomes larger than that of the varnish layer 42, an adhesive tape is accidentally applied to a portion where the varnish layer 42 is not provided. Therefore, the area of the varnish layer 42 needs to be larger than the concealing layer 56.
[0109]
Further, although a caution note 62 is provided in the right piece portion 44 of the varnish layer, this caution note 62 may or may not be provided. Since it is possible to prevent the adhesive tape from being attached to a place where the varnish layer 42 is not provided so as to protrude from the concealment layer 57 by mistake, it is preferable to provide it. As shown in FIG. 3, by clearly indicating the range where the adhesive tape is applied by the right attachment location indication line 63 and the left attachment location indication line 64, the user can adhere to the vicinity of the left attachment location indication line 64. The tape starts to be pasted, covers a part of the overlapping portion 57 that overlaps the varnish layer 42 in the concealing layer 56, and stretches to the vicinity of the right pasting point indicating line 63, and then peels off in the direction of the arrow. The possibility of adhering the adhesive tape to a portion where the varnish layer 42 is not provided by mistake can be reduced. In addition, it begins to stick an adhesive tape in the vicinity of the left sticking location indication line 64, covers a part of the overlapping portion 57 that overlaps the varnish layer 42 in the concealing layer 56, and in the vicinity of the right sticking location indication line 63. It is assumed that a right-handed person is assumed to be peeled off in the direction of the arrow after it is stretched until the left-handed person is reversed.
[0110]
In FIG. 3, the notes 62 are provided at the same time as the information ink layer 41 is provided. However, the notes 62 need not be limited to this. It may be provided at any step, and any method may be used as long as it can be applied. In the present embodiment, the left piece portion 43 of the varnish layer 42 is formed in the shape of an arrow and the right piece portion 44 is formed in a rectangle. However, it is not necessary to limit to this. When the area of the varnish layer 42 is larger than that of the masking layer 56 and the masking layer 56 is provided on the varnish layer 42, a part of the varnish layer 42 comes out from a part of the outer periphery of the masking layer 56, and As long as a part of the masking layer 56 protrudes from a part of the outer periphery of the varnish layer 42, it may be provided in any manner.
[0111]
Next, with reference to FIG. 4, an example of the varnish layer format will be described. In FIG. 4, the concealing layer 73 is made transparent so that the concealed information ink layer 71 is visible, but this is for easy viewing of the figure. In fact, the information ink layer 71 is not concealed. Since it is hidden by 73, it cannot be seen in a normal state.
[0112]
FIG. 4A is a top view of a lottery portion showing another embodiment. In FIG. 4A, 70 is a lottery part, 71 is an information ink layer, 72 is a varnish layer, 73 is a masking layer, 74 is the center of the varnish layer, 75 is the center of the masking layer, 76 is the diameter of the varnish layer, 77 Is the diameter of the masking layer, 78 is the peelable limit line, 79 is the peeled part separated by the peelable limit line of the masking layer, 80 is the remaining part of the masking layer separated by the peelable limit line, 81 is the varnish layer margin Part.
[0113]
4A, the lottery portion 70 is provided on a substrate sheet (not shown), and includes an information ink layer 71, a varnish layer 72, and a concealing layer 73. The varnish layer 72 and the concealing layer 73 are both circular, and the diameter 74 of the varnish layer 72 is designed to be longer than the diameter 76 of the concealing layer 73. Further, the concealing layer 73 is laminated on the varnish layer 72, and the concealing layer 73 is provided so as to be shifted to the lower right from the center 74 of the varnish layer so that the whole does not protrude from the varnish layer 72. ing. That is, the varnish layer 72 has a larger area than the concealing layer 73 and is provided so as to appear more unevenly than the concealing layer 73. The varnish layer blank 81 is the largest place where the varnish layer 72 protrudes from the masking layer 73 by shifting the masking layer 73 to the lower right side of the varnish layer 72. The adhesive tape can be prevented from sticking to the substrate sheet when the layer 73 is peeled off.
[0114]
The peelable limit line 78 is a line segment that indicates where the width of the adhesive tape matches the arc length of the varnish layer 72. When the masking layer 73 is peeled off with the adhesive tape, the entire masking layer 73 cannot be peeled off. The remaining portion 80 side separated by the peelable limit line 78 in the concealing layer 73 cannot be peeled off and remains. Because the center of the masking layer 73 is shifted to the lower right so as not to protrude from the varnish layer 72, the adhesive tape is applied to the substrate sheet on the remaining portion 80 side separated by the peelable limit line 78 of the masking layer 73. It is because the varnish layer 72 has not come out to such an extent that it can prevent sticking. Therefore, when the adhesive tape is attached so as to cover the entire concealing layer 73, the adhesive tape adheres to the substrate sheet on the remaining portion 80 side separated by the peelable limit line 78 in the concealing layer 73. Accordingly, the peelable portion 79 separated by the peelable limit line 78 is the maximum range that can be peeled off, and the information ink layer 71 is provided on the masking layer 73 on the peelable portion 79 side separated by the peelable limit line 78. .
[0115]
Further, for example, the masking layer 73 can be shifted so as to overlap the outer periphery of the varnish layer 72 or can be shifted until a part of the masking layer 73 comes out from the outer periphery of the varnish layer 72. However, if the concealing layer 73 is shifted so as to overlap the outer periphery of the varnish layer 72, depending on the size of the concealing layer 73, the peeled portion 79 separated by the peelable limit line 78 in the concealing layer 73 becomes considerably small. This is not preferable because it is also possible. Further, if the masking layer 73 is shifted so that a part of the masking layer 73 comes out from the outer periphery of the varnish layer 72, the contour of the varnish layer 72 is not recognized by the masking 73 layer, and the varnish layer is mistakenly removed when the masking layer 73 is peeled off. Since there is a possibility that the adhesive tape may be applied to a portion where 72 is not provided, it is advisable to provide a cautionary note such as “Do not apply any more”.
[0116]
FIG. 4B is a top view of a lottery portion showing another embodiment. In FIG. 4B, 85 is a lottery part, 86 is an information ink layer, 87 is a varnish layer, 88 is a hiding layer, 89 is the height of the varnish layer, 90 is the diameter of the hiding layer, 91 is a peelable limit line, Reference numeral 92 denotes a peeled portion separated by the peelable limit line in the masking layer, and 93 is a remaining portion separated by the peelable limit line.
[0117]
In FIG. 4B, a lottery portion 85 is provided on a substrate sheet (not shown) and includes an information ink layer 86, a varnish layer 87, and a concealing layer 88. The varnish layer 87 is an equilateral triangle, and the masking layer 88 is a circle inscribed in the varnish layer 87. Although the masking layer 88 is in contact with the varnish layer 87, each vertex of the triangle protrudes from the masking layer 88 in the varnish layer 87. That is, the varnish layer 87 has a larger area than the masking layer 88 and each vertex protrudes from the masking layer 88. The adhesive tape is prevented from sticking to the substrate sheet by the apexes protruding from the concealing layer 88.
[0118]
The peelable limit line 91 is a line connecting two of the contact points of the three varnish layers 87 and the masking layer 88. If the width of the adhesive tape used for peeling off the masking layer 88 is not less than the length of the peelable limit line 91, the adhesive tape will be stuck on the substrate sheet, which is not preferable. Further, when the masking layer 88 is peeled off using the adhesive tape, the masking layer 88 cannot be completely peeled off, and the remaining portion 93 separated by the peelable limit line 91 of the masking layer 88 remains without being peeled off. . This is because the varnish layer 87 has a triangular shape, and gradually narrows beyond the peelable limit line 91. The information ink layer 86 is provided on the side of the peeled portion 92 separated by the peelable limit line 91 in the concealing layer 88. In order to visually check the information ink layer 86, an adhesive tape is used. One of the two sides is attached in the vicinity of the side parallel to the peelable limit line 91 so that the adhesive tape is not stuck on the substrate sheet, covers the peeled portion 92 separated by the peelable limit line 91, and the peelable limit line It becomes possible by sticking it on the substrate sheet in the vicinity of 91 so as not to stick it, and then peeling it off.
[0119]
In FIG. 4, the size of the remaining portion separated by the peelable limit line in each of the concealing layers in FIGS. 4 (A) and 4 (B) is provided with two or more characters having a size of 0.35 mm or more. It is preferable that the size be able to be obtained. Furthermore, the area of the varnish layer is not only to prevent the adhesive tape from sticking to the substrate sheet when peeling the concealment layer, but also to the area where the varnish layer is not provided by mistake. In order to prevent this, it is necessary to make it larger than the concealment layer. Further, it is preferable to design the varnish layer and the concealing layer so that an adhesive tape having a width of 12 mm or 15 mm, which is often used at home, can be adopted.
[0120]
Moreover, although the concealment layer was fixed to the circle from FIG. 1 to FIG. 4, it is not necessary to limit to this. Further, although the entire information ink layer is concealed by one concealing layer, the present invention is not limited to this, and the information ink layer may be partially covered. In other words, when the information ink layer is the character “around”, it is possible to cover “a”, “ta” and “ri” one by one. Furthermore, since it is sufficient that at least the information ink layer can be concealed, in an extreme example, when the information ink layer is a character “around”, the concealment layer is concealed so as to conceal the character “around”. It is also possible to change to the word “around”. However, if this is done, the information ink layer will be known before the masking layer is peeled off, so it cannot be said to be a preferred masking layer.
[0121]
5 and 6 show another embodiment of the present invention. FIG. 5 is a cross-sectional view showing an example of the present embodiment, and FIG. 6 is a development view in which only the lot portions are developed in the stacking order. A top view when the lottery portion of FIGS. 5 and 6 is provided in a lottery card or the like is the same as FIG. In FIG. 5, 101 is a substrate sheet, 102 is a lottery part, 103 is a base ink layer, 104 is an information ink layer, 105 is a varnish layer, 106 is a concealing layer, 107 is a diameter of the base ink layer, and 108 is an end point of the information ink layer. , 109 is the diameter of the varnish layer 105, and 110 is the diameter of the masking layer 106. 6 (A) is a top view of the base ink layer, FIG. 6 (B) is a top view of the information ink layer, FIG. 6 (C) is a top view of the varnish layer, and FIG. 6 (D) is a top view. (E) is a top view seen from a normal state after all layers are laminated, 102 is a lottery part, 103 is a base ink layer, 104 is an information ink layer, 105 is a varnish layer 106 is a concealing layer, 107 is the diameter of the base ink layer, 108 is the length from the end point to the end point of the information ink layer, 109 is the diameter of the varnish layer 105, 110 is the diameter of the concealing layer 106, and 111 is the base ink layer 103. , 112 is the center of the varnish layer 109, 113 is the center of the masking layer 106, and 114 is the center of the lottery portion.
[0122]
5 and 6, the lottery portion 102 is provided on the substrate sheet 101, and includes a base ink layer 103, an information ink layer 104, a varnish layer 105, and a concealing layer 106. The base ink layer 103 has a circular shape whose diameter is the maximum value of the length 108 from the end point to the end point of the information ink layer 104, and is directly provided on the substrate sheet 101. The information ink layer 104 is a layer that forms a “spot” or “displacement”, and is provided on the base ink layer 103 so as not to come out of the range of the base ink layer 103. Both the varnish layer 105 and the masking layer 106 have a circular shape, and the centers 112 and 113 of the varnish layer 105 and the masking layer 106 are provided so as to overlap the center 111 of the base ink layer 103. The diameter 107 of the base ink layer 103 and the diameter 110 of the masking layer 106 are substantially the same length, and the diameter 108 of the varnish layer 105 is designed to be longer than the diameter of the base ink layer 103 and the masking layer 106. Therefore, when viewed from the front, the base ink layer 103 and the information ink 104 cannot be seen. Further, the varnish layer 105 has a larger area than the concealing layer 106, and the varnish layer 105 appears to protrude uniformly from the outer periphery of the concealing layer 106.
[0123]
Those given the same names as in FIG. 1 are the same, so the explanation is omitted, and the base ink layer 103 will be explained. The base ink layer 103 is a layer that can be laminated with the information ink layer 104 in any order. In this embodiment, it is provided under the information ink layer 104, but the present invention is not limited to this, and the information ink layer 104 may be provided. The base ink layer 103 is composed of characters, symbols, figures, or a combination thereof, and is at least partially overlapped with the information ink layer 104. In the present embodiment, the base ink layer 103 has a pattern made of a set of rectangles, and overlaps with a part of the information ink layer 104. Here, overlapping means that, for example, when the base ink layer 103 and the information ink layer 104 are provided by a printing method, at least a part of the printed portions forming the respective layers overlap. In addition, even if the lottery information is projected as a shadow on the outermost layer by applying strong light from the back surface of the substrate sheet 101, the base ink layer 103 plays a role of making it difficult to decode the lottery information due to the projected shadow. Therefore, even if it does not overlap with the information ink layer 104, it is not necessary to overlap if it can play this role. Even if the base ink layer 103 shines strong light from the back surface of the substrate sheet 101 and copies the information ink layer 104 as a shadow on the outermost layer, it becomes more difficult to decipher the information ink layer 104 by the projected shadow. Alternatively, the shadow of the information ink layer 104 can be prevented from being copied. That is, if the base ink layer 103 is provided under the information ink layer 104 with a pattern, it is attempted to project the information ink layer 104 onto the concealment layer 106 which is the outermost layer by applying strong light from the back surface of the substrate sheet 101. However, since not only the shadow of the information ink layer 104 but also the shadow of the base ink layer 103 is reflected on the masking layer 106, it is difficult to decipher the information ink layer 104. Is provided under the information ink layer 104, even if it is intended to project the information ink layer 104 onto the concealing layer 106, which is the outermost layer, by applying strong light from the back surface of the substrate sheet 101. The layer 103 can prevent the shadow of the information ink layer 104 from being projected. The same applies when the base ink layer 103 is provided on the information ink layer 104. If the base ink layer 103 is provided as a pattern on the information ink layer 104, strong light is applied from the back surface of the substrate sheet 101. Even if the information ink layer 104 is to be copied to the concealing layer 106 which is the outermost layer, not only the shadow of the information ink layer 104 but also the shadow of the base ink layer 103 is also copied to the concealing layer 106. The layer 104 can be difficult to decipher, and if the base ink layer 103 is provided on the information ink layer 104 as a solid, the information ink layer 104 is applied by applying strong light from the back surface of the substrate sheet 101. Even if an attempt is made to project on the concealing layer 106 which is the outermost layer, the shadow of the information ink layer 104 can be prevented from being projected by the solid base ink layer 103.Therefore, since the information ink layer 104 and the base ink layer 103 are laminated in any order on the substrate sheet 101, strong light is applied from the back surface of the substrate sheet 101 to make the information ink layer 104 the outermost layer. Copying as a shadow can also make it difficult to decipher the information ink layer 104 by the projected shadow or prevent the shadow of the information ink layer 104 from being copied. It is also possible to employ a very thin paper having a low surface strength, which is called a finely coated paper in gravure printing, as the substrate sheet 101. Further, since the varnish layer 105 is provided so as to have a larger area than the concealing layer 106 and so that the varnish layer 105 protrudes evenly from the outer periphery of the concealing layer 106, paper having a low surface strength can be used. Only the concealment layer 106 can be peeled off without causing paper peeling.
[0124]
5 and 6, the base ink layer 103 is a circle whose diameter is the maximum value of the length 108 from the end point to the end point of the information ink layer 104, but is not limited thereto. It may be smaller than the information ink layer 104 or larger than the information ink layer 104. For example, the base ink layer 103 may be provided on the entire surface of the substrate sheet 101, and then the information ink layer 104, the varnish layer 105, and the concealing layer 106 may be laminated in arbitrary positions on the base ink layer 103 in this order. .
[0125]
In the present invention, the base ink layer 103 makes it difficult for the information ink layer 104 to be projected as a shadow on the concealment layer 106 by strong light from the back surface of the substrate sheet 101, or even if the information ink layer 104 is projected as a shadow. It plays a role of making it difficult to decipher the lottery information according to, and should not be concealed by the concealment layer 106. Therefore, the underlying ink layer 103 may be visible in a normal state, and it is not necessary to cover the entire underlying ink layer 103 with the concealing layer 106. Since the varnish layer 105 is also provided to prevent the paper from being peeled off when the concealing layer 106 is peeled off, if the concealing layer 106 is provided so as to be able to be peeled without removing the paper, It is not necessary to cover the entire ink layer 103. However, it is needless to say that the larger the area covered by the varnish layer 105, the more the concealing layer 106 can be peeled off without peeling off the paper, regardless of where the adhesive tape is applied.
[0126]
In FIGS. 5 and 6, the base ink layer 103 is a pattern made of a set of rectangles, but it is not necessary to be limited to this. If the ground ink layer 103 can play a role of making it difficult to decipher the lottery information by the projected shadow even if the lottery information is projected as a shadow on the outermost layer by applying strong light from the back surface of the substrate sheet 101, The base ink layer 103 may be any character, symbol, figure, or a combination thereof. For example, it may be solid, a color image, or a set of characters. However, when the information ink layer 104 is “around”, the base ink layer 103 is set to “around” with characters having the same size as the information ink layer 104, and is further provided so as to overlap the information ink layer 104. When the information ink layer 104 is projected as a shadow on the concealing layer 106 by applying strong light from the back surface, the shadow may become deeper, and thus it cannot be said that the preferred base ink layer 103 is a form. Further, when the information ink layer 104 is “around”, the base ink layer 103 is provided as “displaced” with characters of the same size as the information ink layer 104 so as to overlap the information ink layer 104, or the information ink layer 104 If the character is smaller than the layer 104, and it is provided as if it is “displaced out of shape” as if it were a pattern, then when the concealing layer 106 is peeled off, it will not be clear whether the lottery is “winning” or “out of”, and it will be confused Therefore, it cannot be said that it is a preferable form of the base ink layer 103. However, providing the base ink layer 103 with characters smaller than the information ink layer 104 and the same as the information ink layer 104 as if in a pattern does not cause the above-described confusion. Even if the ink layer 104 is projected as a shadow on the concealing layer 106, it is considered to play a role of making it difficult to decode the ink layer 104. In this case, if the base ink layer 103 is not sized so that the base ink layer 103 is concealed by the concealing layer 106 as shown in FIGS. Therefore, it is necessary to pay attention to the size of the base ink layer 104.
[0127]
Further, the color and density of the base ink layer 103 are not limited, and any color may be used, and any density may be used. For example, when the base ink layer 103 is provided below the information ink layer 104 and is solidly applied, the base ink layer 103 provided with a darker color than the information ink layer 104 is light from the back surface of the substrate sheet 101. However, it is not necessary to limit to this. When the base ink layer 103 is provided on the information ink layer 104, it is necessary to provide the base ink layer 103 so that the information ink layer 104 is not invisible.
[0128]
5 and 6, the varnish layer 105 is a circle having an area larger than that of the concealment layer 106. However, the present invention is not limited to this, and the varnish layer 105 is not limited to this as shown in FIGS. Of course, it is possible to deform, as shown in FIG. 2 and FIG. 3, the varnish layer 105 is provided so as to have a larger area than the concealing layer 106 and come out from a part of the outer periphery of the concealing layer 106. It is also possible to provide the concealing layer 106 so as to have a smaller area than the varnish layer 105 and to exit from a part of the outer periphery of the varnish layer 105. Further, as shown in FIGS. 2 and 3, the varnish layer 105 is provided so as to have a larger area than the masking layer 106 and come out from a part of the outer periphery of the masking layer 106, as shown in FIGS. Further, by providing the concealing layer 106 so as to have an area smaller than that of the varnish layer 105 and to come out from a part of the outer periphery of the varnish layer 105, strong light is applied from the back surface of the substrate sheet 101, and the information ink layer 104. When the concealment layer 106 of the selected lottery part 102 is peeled off together with the illegal act of reading the lottery information as a shadow on the concealment layer 106 which is the outermost layer and reading the lottery information in advance, it will be peeled off. It will also be possible to prevent fraudulent acts of returning to the original as if not. Further, since the varnish layer 105 has a larger area than the concealing layer 106 and is provided so as to protrude from the outer periphery of the concealing layer 106, it is needless to say that the concealing layer 106 can be peeled off without causing paper peeling. Yes.
[0129]
5 and 6, the concealing layer 106 is fixed to a circle, but it is not necessary to limit to this. Further, although the entire information ink layer 104 is concealed by one concealing layer 106, the present invention is not limited to this, and the information ink layer 104 may be partially covered. That is, when the information ink layer 104 has the character “around”, it is possible to cover “a”, “ta”, and “ri” one by one. Furthermore, since it is sufficient that at least the information ink layer 104 can be concealed, in an extreme example, when the information ink layer 104 is a character “around”, the character “around” is concealed. The concealing layer 106 may be changed to the letter “around”. However, if this is done, the information ink layer 104 can be identified before the masking layer 106 is peeled off, and therefore it cannot be said to be a preferable masking layer 106.
[0130]
5 and 6 is formed on the substrate sheet, first, the base ink layer 103 is applied on the base sheet 101 by the gravure printing method, and then partially overlaps the base ink layer 103. The information ink layer 104 is applied by a gravure printing method, and then the varnish layer 105 is gravure so as to cover the information ink layer 104 and also onto the substrate sheet 101 on which nothing has been printed yet. The masking layer 106 is applied by a gravure printing method and then applied by a printing method. The description of the layers with the same names as in FIG. 1 is the same as in FIG. In this embodiment, a rosin resin is used for the base ink layer. However, it is not necessary to limit to this, and the ink used for normal gravure printing can be used. In addition, as shown in FIG. 1A, it is also possible to provide a finding as a picture part or a caution note as a picture part on the substrate sheet 101 other than the lottery part 102. As a means for providing the pattern part on the substrate sheet 101 other than the lottery part 102, a means for providing the pattern part by providing the base ink layer 103 on the entire surface of the substrate sheet may be adopted. A means of providing the ink layer 103 may be adopted, and the combination thereof is free. Further, any method may be adopted as long as the application method can be applied, but the description is omitted because it overlaps with the application method of FIG.

7 and 8 show another embodiment of the present invention. FIG. 7 is a cross-sectional view showing an example of the present embodiment, and FIG. 8 is a developed view in which only the lot portions are developed in the stacking order. Since the top view when it is provided on a lottery card or the like is the same as FIG. In FIG. 7, 121 is a substrate sheet, 122 is a lottery part, 123 is an information ink layer, 124 is a varnish layer, 125 is an ink layer, 126 is a concealing layer, 127 is the maximum value of the length from end point to end point of the information ink layer, 128 is the diameter of the varnish layer 124, 129 is the diameter of the ink layer 125, and 130 is the diameter of the masking layer 126. 8A is a top view of the information ink layer, FIG. 8B is a top view of the varnish layer, FIG. 8C is a top view of the ink layer, and FIG. 8D is a concealment. FIG. 8 (E) is a top view as seen from the normal state after all layers are laminated, 122 is a lottery part, 123 is an information ink layer, 124 is a varnish layer, and 125 is an ink layer. , 126 is a masking layer, 127 is the length from the end point of the information ink layer, 128 is the diameter of the varnish layer 124, 129 is the diameter of the ink layer 125, 130 is the diameter of the masking layer 126, and 131 is the center of the varnish layer 132 is the center of the ink layer, 133 is the center of the masking layer, and 134 is the center of the lottery portion.
[0132]
7 and 8, the lottery portion 122 is provided on the substrate sheet 121 and includes an information ink layer 123, a varnish layer 124, an ink layer 125, and a concealing layer 126. The information ink layer 123 is a layer that forms “around” or “out of contact”, and is provided on the substrate sheet 121. The varnish layer 124 has a circular shape, and is provided on the substrate sheet 121 so as to cover the information ink layer 123 and also on the substrate sheet 121. The diameter of the varnish layer 124 is designed to be longer than the ink layer 125 and the concealment 126 layer. The ink layer 125 and the masking layer 126 are both circles having a diameter 127 that is the maximum value of the length 127 from the end point to the end point of the information ink layer 123. The ink layer 125 and the masking layer 126 are formed on the varnish layer 124. The information ink layer 123 is laminated in this order. Further, the varnish layer 124, the ink layer 125, and the concealing layer 126 are provided such that the centers thereof overlap the centers of the lottery portions 134. Therefore, when viewed from the front, the information ink layer 123 and the ink layer 125 are not visible by the masking layer 126. Also, the varnish layer 124 has a larger area than the masking layer 126 and appears to protrude evenly from the outer periphery of the masking layer 126.
[0133]
Since the same reference numerals as those in FIG. 1 are the same, the description is omitted and the ink layer 125 will be described. The ink layer 125 is a layer that can be laminated on the varnish layer 124 with the masking layer 126 in any order. In this embodiment mode, it is provided under the concealment layer 126, but the present invention is not limited to this, and the concealment layer 126 may be provided. The ink layer 125 is composed of characters, symbols, figures, or a combination thereof, and at least partially overlaps the information ink layer 123. In the present embodiment, the ink layer 125 is a pattern made of a set of rectangles, and overlaps with a part of the information ink layer 123. Here, overlapping means that, for example, when the information ink layer 123 and the ink layer 125 are provided by a printing method, at least a part of the printed portions forming the respective layers overlap. When the ink layer 125 is provided under the masking layer 126, the varnish layer 124 is interposed between the information ink layer 123 and the ink layer 125, but the information ink layer 123 and the ink layer 125 overlap through the varnish layer 124. That's what it means. Also, when the ink layer 125 is provided on the masking layer 126, the varnish layer 124 and the masking layer 126 are interposed between the information ink layer 123 and the ink layer 125, but information is transmitted through the varnish layer 124 and the masking layer 126. That is, the ink layer 123 and the ink layer 125 overlap. The ink layer 125 plays a role of making it difficult to decipher the lottery information due to the projected shadow even if the lottery information is projected as a shadow on the outermost layer by applying strong light from the back surface of the substrate sheet 121. Even if it does not overlap with the information ink layer 123, it is not necessary to overlap if it can play this role. By having the concealing layer 126 and the ink layer 125 that can be laminated in any order on the varnish layer 124, the information ink layer 123 is projected as a shadow on the outermost layer by applying strong light from the back surface of the substrate sheet 121. It becomes possible to make it difficult to decipher the information ink layer 123 due to the shadow, or to prevent the shadow of the information ink layer 123 from being copied. That is, if the ink layer 125 is provided under the concealment layer 125 with a pattern or the like, even if it tries to project the information ink layer 125 onto the concealment layer 126 which is the outermost layer by applying strong light from the back surface of the substrate sheet 121. In addition, since not only the shadow of the information ink layer 123 but also the shadow of the ink layer 125 is reflected on the concealing layer 126, it is difficult to read only the shadow of the information ink layer 123, and the ink layer If 125 is solid and provided under the concealing layer 126, the solid ink is applied even if the information ink layer 123 is projected onto the concealing layer 126 which is the outermost layer by applying strong light from the back surface of the substrate sheet 121. The layer 125 can prevent the shadow of the information ink layer 123 from being projected. The same applies to the case where the ink layer 125 is provided on the concealing layer 126. If the ink layer 125 is provided on the concealing layer 126 with a pattern, the information ink layer 123 is irradiated with strong light from the back surface of the substrate sheet 121. Even if the ink layer 125 is to be copied onto the outermost ink layer 125, not only the shadow of the information ink layer 123 but also the pattern of the ink layer 125 can be seen in the ink layer 125 which is the outermost layer. If the ink layer 125 is solid and provided on the concealing layer 126, strong light is applied from the back surface of the substrate sheet 121 to make the information ink layer 123 the outermost layer. Therefore, it is possible to prevent the shadow of the information ink layer 123 from being projected by the solid ink layer 125. Therefore, since the ink layer 125 is laminated on the varnish layer 124 in any order with the concealing layer 126, strong light is applied from the back surface of the substrate sheet 121 to shadow the information ink layer 123 on the outermost layer. Even if it is projected as, it becomes possible to make it difficult to decipher the lottery information by the projected shadow, or it is possible to prevent the shadow of the information ink layer 123 from being projected, and the lottery information before the masking layer 126 is peeled off. It is possible to prevent the injustice of reading. Therefore, for example, a very thin paper having a weak surface strength, which is commonly called a finely coated paper by gravure printing, can be used for the substrate sheet 121. In addition, since the varnish layer 124 is provided so that the area of the varnish layer 124 is larger than that of the masking layer 126 and so that the varnish layer protrudes more uniformly than the outer periphery of the masking layer 126, the masking layer 126 does not cause paper peeling. Can be peeled off.
[0134]
7 and 8, the ink layer 125 is a circle whose diameter is the maximum value 127 of the length from the end point to the top of the information ink layer 123, but is not limited thereto. For example, it may be provided smaller than the information ink layer 123 so that a part thereof overlaps with the information ink layer 123, or of course, may be provided larger than the information ink layer 123, or provided on the entire surface of the substrate sheet 121. May be. However, the ink layer 125 is provided on the varnish layer 124 regardless of whether the ink layer 125 is provided below the masking layer 126 or on the masking layer 126. When the ink layer 125 is provided on the varnish layer 124, the outline of the varnish layer 124 becomes unclear, and the adhesive tape may stick to the paper when the concealing layer 126 is peeled off. For example, the information ink layer 123 is partially provided on the substrate sheet 121, and then the varnish layer 124 is provided so as to cover the information ink layer 123, and then the ink layer is formed on the substrate sheet 121 including the varnish layer 124. 124 is provided on one side, and then a concealing layer 126 is partially provided on the ink layer 124 so as to conceal only the information ink layer 123, the outline of the varnish layer 124 is unclear due to the ink layer 125. As a result, the adhesive tape may be attached to the substrate sheet 121 when the masking layer is peeled off. Therefore, it is preferable that the ink layer 125 is not larger than the area of the varnish layer 124 and provided so as not to come out of the outer periphery of the varnish layer 124. Furthermore, it is preferable to provide the same area, the same shape, and the same position as the concealing layer 126. However, even if the ink layer 125 is provided so that the outline of the varnish layer 124 is not known, the possibility described above is reduced if the outline of the varnish layer 124 is indicated by providing a cautionary note. Furthermore, when the ink layer 125 is provided on the masking layer 126, not only the contour of the varnish layer 124 but also the contour of the masking layer 126 becomes unclear, a cautionary note is provided to provide the varnish layer 124. And the range of the concealing layer 126 are preferably shown respectively.
[0135]
In FIGS. 7 and 8, the ink layer 125 is a pattern made of a set of rectangles, but it is not necessary to be limited to this. The ink layer 125 prevents the information ink layer 123 from being projected as a shadow on the concealment layer 126 by strong light from the back surface of the substrate sheet 121, or even if the information ink layer 123 is projected as a shadow, the lottery information can be decoded by the shadow. The ink layer 125 may be anything such as characters, symbols, graphics, or a combination thereof as long as it can play the role of making it difficult. For example, it may be solid, a color image, or a set of characters. However, when the information ink layer 123 is “around”, the ink layer 125 is set to “around” with characters having the same size as the information ink layer 123, and further provided so as to overlap the information ink layer 123. When the information ink layer 123 is copied as a shadow on the concealing layer 126 by applying strong light from the back side, the shadow may become darker, so that the ink layer 125 is not a preferable form. That is, providing the ink layer 125 so as to be exactly the same as the information ink layer 123 is not a preferable form of the ink layer 125. However, when the information ink layer 123 is “around”, providing the ink layer 125 with characters smaller than the information ink layer 123 as if “around” as if it were a pattern, It can be said that it is a form of the ink layer 125 that can be adopted because it is considered to play a role of making the decoding difficult even if it is projected onto the concealing layer 126.
[0136]
Further, the color and density of the ink layer 125 are not limited, and any color may be used, and any density may be used. By making the color darker than the information ink layer 123, it is possible to effectively prevent the fraud of reading the lottery information before peeling the concealment layer 126, which is preferable. However, it is not necessary to limit to this.
[0137]
When the ink layer 125 is made of characters, symbols, graphics, or a pattern made of a combination thereof, the aesthetic appearance can be improved. For example, if the ink layer 125 provided under the concealing layer is made of characters, symbols, graphics, or a pattern made of a combination thereof, the concealing layer 126 looks like a watermark pattern of Japanese paper when viewed in a normal state. The pattern of the ink layer 125 can be seen and the aesthetic appearance can be improved. Further, when the ink layer 125 provided on the concealing layer is made of characters, symbols, graphics, or a pattern made of a combination thereof, the concealing layer can be seen between the patterns provided when viewed in a normal state. Aesthetics can be improved. At this time, it is preferable that the pattern or the like is provided in white because the overlapping portion with the information ink layer 123 increases and the information ink layer 123 is also hidden by the ink layer 125.
[0138]
7 and 8, the varnish layer 124 is a circle having a larger area than the concealing layer 126. However, the varnish layer 124 is not limited to this, and the varnish layer 124 is not limited to this as shown in FIGS. Of course, deformation is possible, and as shown in FIGS. 2 and 3, the varnish layer 124 has a larger area than the concealment layer 126 and is provided so as to protrude from a part of the outer periphery of the concealment layer 126. It is also possible to provide the concealing layer 126 so as to have a smaller area than the varnish layer 124 and to exit from a part of the outer periphery of the varnish layer 124. 2 and 3, the varnish layer 124 is provided so as to have a larger area than the concealing layer 126 and come out of a part of the outer periphery of the concealing layer 126, as shown in FIGS. By providing the concealing layer 126 so that it has a smaller area than the varnish layer 124 and exits from a part of the outer periphery of the varnish layer 124, the information ink layer 123 is applied by applying strong light from the back surface of the substrate sheet 121. When the concealment layer 126 of the selected lottery part 122 is peeled off, it is not peeled off as well as the fraudulent act of displaying the lottery information in advance as a shadow on the concealment layer 126 which is the outermost layer. It also becomes possible to prevent the illegal act of returning to the original. Further, since the varnish layer 124 has a larger area than the concealing layer 126 and is provided so as to protrude from the outer periphery of the concealing layer 126, it goes without saying that the concealing layer 126 can be peeled off without causing paper peeling. Yes.
[0139]
7 and 8, the concealing layer 126 is fixed to a circle, but it is not necessary to limit to this. Further, although the entire information ink layer 123 is concealed by one concealing layer 126, the present invention is not limited to this, and the information ink layer 123 may be partially covered. That is, when the information ink layer 123 has the character “around”, it is possible to cover “a”, “ta”, and “ri” one by one. Furthermore, since it is sufficient that at least the information ink layer 123 can be concealed, to give an extreme example, when the information ink layer 123 is a character of “around”, the character of “around” is concealed. The concealing layer 126 can be changed to the letter “around”. However, if it does in this way, since it will be understood what the information ink layer 123 is before peeling the concealing layer 126, it cannot be said that it is a preferable concealing layer 126.
[0140]
To form the lottery portion of FIGS. 7 and 8 on the substrate sheet, first, the information ink layer 123 is applied on the base sheet 121 by a gravure printing method, and then the information ink layer 123 is covered so as to cover it. And, the varnish layer 124 is applied by a gravure printing method so as to cover the substrate sheet 121 on which nothing has been printed yet, and then the ink layer 125 is applied on the varnish layer by a gravure printing method, The masking layer 126 is applied on the ink layer 124 by a gravure printing method. The description of the bag with the same name as FIG. 1 is the same as FIG. The ink layer must be peeled off with adhesive tape together with the hiding layer. In order to do this, the concealing layer and the resin layer may be the same. Therefore, the ink layer is formed of a nitrocellulose-based resin indigo ink. Therefore, the ink layer exhibits low adhesion and low adhesion with the varnish layer, and exhibits strong adhesion and strong adhesion with the concealing layer. When the concealing layer is peeled off with an adhesive tape, The ink layer can be peeled off together. In this embodiment, the ink layer is a nitrocellulose-based indigo ink, but it is not necessary to limit to this. Any material may be used as long as it can be peeled off together with the hiding layer. For example, silver ink may be used, or a color image may be formed by combining several colors. In addition, as shown in FIG. 1A, it is also possible to provide a finding as a picture part or a caution note as a picture part on the substrate sheet 121 other than the lottery part 122. As a means for providing the pattern portion on the substrate sheet 121 other than the lottery portion 122, a means for providing the pattern portion by providing the ink layer 125 on the entire surface of the substrate sheet may be adopted, or a means for providing the pattern portion independently. May be adopted, and the combination is free. Further, any method may be adopted as long as the application method can be applied, but the description is omitted because it overlaps with the application method of FIG.
[0141]
Next, an example of the ink layer pattern will be described with reference to FIG.
[0142]
FIG. 9 is a development view of a lottery part representing another embodiment, on the substrate sheet so as to cover the substrate sheet, the information ink layer positioned on the substrate sheet and having lottery information, and at least the lottery information. A varnish layer provided on the varnish layer, a camouflaged information ink layer provided so as to be peelable from the varnish layer, and a camouflage information ink layer, and at least the lottery information and camouflage information. And a concealing layer provided so as to be peelable together with the camouflaged information ink layer, and the varnish layer has at least an area larger than the concealing layer and protrudes from the outer periphery of the concealing layer. It is the expanded view which developed the lottery part of the printed matter characterized by having provided. A top view when it is provided on a lottery card or the like is omitted because it is the same as FIG. 1A, and a sectional view is omitted because it is the same as FIG. 9A is a top view of the information ink layer, FIG. 9B is a top view of the varnish layer, FIG. 9C is a top view of the camouflaged information ink layer that is the ink layer, and FIG. 9D is a concealment. FIG. 9E is a top view of the layers viewed from a normal state after all the layers are stacked. In FIG. 9, 140 is a lottery part, 141 is an information ink layer, 142 is a varnish layer, 143 is an impersonation information ink layer that is an ink layer, 144 is a hiding layer, 145 is the length from the end point to the end point of the information ink layer. 146 is the diameter of the varnish layer 142, 147 is the length from the end point to the end point of the camouflaged information ink layer 143, which is an ink layer, 148 is the diameter of the masking layer 144, 149 is the center of the information ink 141, and 150 is the varnish layer 142 , 151 is the center of the fake information ink layer 143 which is an ink layer, 152 is the center of the concealing layer 144, and 153 is the center of the lot portion 140 after all the layers are stacked.
[0143]
In FIG. 9, the lottery portion 140 is provided on a substrate sheet (not shown), and includes an information ink layer 141, a varnish layer 142, a camouflaged information ink layer 143 that is an ink layer, and a concealing layer 144. The information ink layer 141 is a layer that forms “around” or “out of contact” and is provided directly on the substrate sheet. The varnish layer 142 has a circular shape, and is provided on the substrate sheet so as to cover the information ink 141 layer and also cover the substrate sheet. In addition, the diameter 146 of the varnish layer 142 is designed to be longer than the diameter 148 of the concealing layer 144. The camouflage information ink layer 143, which is an ink layer, is provided on the varnish layer 142, and forms “winning” or “missing” that is lottery information of camouflage. The camouflaged information ink layer 143 has the same size as the information ink layer 141 and is provided so as to overlap the information ink layer 141. The masking layer 144 is a circle having the diameter of the maximum length 145 from the end point to the end point of the information ink layer 141, and is provided on the camouflaged information ink layer 143. The masking information ink layer 141 and the camouflaged information ink layer 143 is concealed. All layers are laminated in the order of the information ink layer 141, the varnish layer 142, the camouflaged information ink layer 143, and the concealing layer 144 so that the center thereof overlaps the center 153 of the lottery portion. Here, the center of the information ink layer 141 and the camouflaged information ink layer 143 is a point where the horizontal midpoint and the vertical midpoint overlap. Therefore, when viewed from the front, the information ink layer 141 and the camouflaged information ink layer 143 cannot be seen by the masking layer 144. The varnish layer 142 has a larger area than the masking layer 144 and appears to protrude evenly from the outer periphery of the masking layer 144.
[0144]
Since the same names as those in FIG. 1 are the same, the description is omitted, and the camouflaged information ink layer 143 which is an ink layer will be described. The camouflaged information ink layer 143, which is an ink layer, is an ink layer having fake lottery information, and when the information ink layer 141 is projected onto the outermost layer by applying strong light from the back surface of the substrate sheet, the information ink layer 141 is a layer that plays a role of copying lottery information (fake lottery information) other than the lottery information of 141 to the outermost layer. The camouflaged information ink layer 143 can make it difficult to determine whether the information ink layer 141 has “winning” or “failed”. Here, the fraudulent lottery information is lottery information other than the lottery information included in the information ink layer 141, and is information representing the opposite meaning to the lottery information included in the information ink layer 141, for example.
[0145]
The lottery portion in FIG. 9 shows a winning lot, and the information ink layer 141 is provided with the word “around”, whereas the disguised information ink layer 143 is called “off” provided in the peeling lottery. Letters are provided. Furthermore, the characters “off” are provided to be exactly the same as “out” of the lottery ticket. The camouflaged information ink layer 143 and the information ink layer 141 have the same maximum length from the end point in the vertical direction to the end point and the maximum length from the end point in the horizontal direction to the end point, and Are provided so that their centers overlap. That is, although the varnish layer 142 is interposed therebetween, the characters “around” included in the information ink layer 141 and the characters “off” included in the fake information ink layer 143 are provided so as to overlap vertically.
[0146]
Therefore, since it has the camouflaged information ink layer 143, even if it tries to decipher the lottery information using the shadow by projecting the information ink layer 141 on the outermost layer as a shadow by applying strong light from the back side of the substrate sheet, the lottery It can be difficult to determine whether a portion is a winning lot or not. That is, when strong light is applied from the back surface of the substrate sheet and the information ink layer 141 is projected as a shadow on the concealing layer 144 that is the outermost layer, the characters “around” of the information ink layer 141 and the counterfeit information ink layer 143 You can see the overlapping “letter” characters. Because the letters overlap, it is difficult to determine what is written, even if you can understand that the letters “around” and “out of” overlap. It is very difficult to determine whether the information ink layer 141 has “around” or “out of”. Therefore, it can be difficult to determine which lottery portion 140 is a winning lottery or the like in which lottery portions 140 are provided on a substrate sheet. Furthermore, since the varnish layer 142 has a larger area than the concealing layer 144 and protrudes from the outer periphery of the concealing layer 144, the concealing layer 144 can be peeled without causing paper peeling.
[0147]
The masking layer 144 is positioned on the camouflaged information ink layer 143 and masks the information ink layer 141 and the camouflaged information ink layer 143. The concealment layer 144 conceals not only the lottery information but also the camouflaged information ink layer 143 because the camouflaged information ink layer 143 has the camouflaged lottery information 143 so that the information ink is irradiated with strong light from the back surface of the substrate sheet. When the layer 141 is projected on the outermost layer, it is possible to make it difficult to determine whether the information ink layer 141 has “winning” or “failed”. This is because if the information ink layer 143 can be seen, it will be understood what the lottery information the information ink layer 141 has.
[0148]
In FIG. 9, the varnish layer 142 is a circle having a larger area than the concealment layer 144. However, the present invention is not limited to this, and the varnish layer 142 may be deformed as shown in FIGS. Of course, as shown in FIGS. 2 and 3, the varnish layer 142 has a larger area than the concealing layer 144 and is provided so as to protrude from a part of the outer periphery of the concealing layer 144. It is also possible to provide 144 so as to have a smaller area than the varnish layer 142 and to exit from a part of the outer periphery of the varnish layer 142. 2 and 3, the varnish layer 142 is provided so as to have a larger area than the concealing layer 144 and come out from a part of the outer periphery of the concealing layer 144. Furthermore, by providing the concealing layer 144 with an area smaller than that of the varnish layer 142 and coming out from a part of the outer periphery of the varnish layer 142, the information ink layer 141 is irradiated with strong light from the back surface of the substrate sheet. In addition to the fraudulent act of reading the lottery information as a shadow on the outermost concealment layer 144 and reading the lottery information in advance, when the concealment layer 144 of the selected lottery part 140 is peeled off, it is removed as if It will also be possible to prevent fraudulent actions such as undoing as if there were none. Further, since the varnish layer 142 has a larger area than the concealing layer 144 and is provided so as to protrude from the outer periphery of the concealing layer 144, it is needless to say that the concealing layer 144 can be peeled off without causing paper peeling. Yes.
[0149]
In the present embodiment, the concealing layer 144 is a circle whose diameter is the maximum value of the length 145 from the end point of the information ink layer 141 to the end point. However, the present invention is not limited to this. At least, the information ink layer 141 and the camouflaged information ink layer 143 may be any shape as long as they can be concealed. In the present embodiment, the information ink layer 141 and the camouflaged information ink layer 143 have the varnish layer 142 interposed therebetween, but overlap each other, so that when the information ink layer 141 and the camouflaged information ink layer 143 appear as shadows on the concealment layer 144, characters are displayed. Can not be read as. Therefore, for example, even if the information ink layer 141 and the camouflaged information ink layer 143 form the concealment layer 144 in an overlapping manner, it is determined whether the information ink layer 141 has lottery information or camouflaged information. Since the information ink layer 141 and the camouflaged information ink layer 143 overlap each other, it is possible to form the concealing layer 144 in the same shape. In addition, if the shape of the masking layer 144 is formed in a manner in which the information ink layer 141 and the camouflaged information ink layer 143 overlap as described above, the raw material of the masking layer 144 can be minimized.
[0150]
Furthermore, in this embodiment, the camouflaged information ink layer 143 is peeled off together with the masking layer 144 because the bond strength with the varnish layer 142 is weak and the bond strength with the masking layer 144 is strong. Therefore, only the information ink layer 141 can be visually observed after the masking layer 144 is peeled off. Moreover, since the camouflaged information ink layer 143 is peeled off together with the concealing layer 144, it is attached to the adhesive tape after peeling off. For example, in the case where the lottery portion 140 is a loose lottery, when the concealing layer 144 is peeled off, the characters “separate” appear on the substrate sheet, and the letters “hit” are stuck on the adhesive tape after peeling. become. Therefore, when looking at the adhesive tape, the word “around” can be seen together with the concealing layer 144, so the word “around” on the adhesive tape is pointed to, and “the word“ around ”is peeled off. There is a possibility that a misunderstanding such as “is.” In order to prevent such a situation from occurring, it is advisable to provide a winning lot sample near the lot portion.
[0151]
In the present embodiment, the information ink layer 141 provided in the lottery lot is the same as the information ink layer 141 provided in the lottery, but the present invention is not limited to this. Furthermore, even in the type of lottery in which only a lottery ticket is provided that provides information on winning, by providing the forged information ink layer 143, it is possible to effectively prevent an illegal act of reading lottery information in advance. . That is, the information ink layer 141 that provides information such as “winning” information only on the winning lot is formed on the information ink layer 141, and the winning type is that the information ink layer 141 is not formed on the winning lottery. In the lottery, if the same information as the lottery information ink layer 141 is provided in the lottery information ink layer 143 in the lottery information ink 143, the lottery information ink layer 141 is strong from the back side of the substrate sheet. Even if the information ink layer 141 is projected as a shadow on the outermost layer by shining light, the information corresponding to the winning will be projected as a shadow on the outermost layer of all the lot portions 140, and which lottery portion is a true winning lot. It can be very difficult to determine whether this is the case. In this case, the winning lottery has the information ink layer 141, the varnish layer 142, and the concealing layer 144, whereas the distancing lottery has the varnish layer 142, the camouflaged information ink layer 143, and the concealing layer 144. The entire lottery portion 140 has the same thickness, but the winning lot is provided with an information ink layer 141 on a substrate sheet, a varnish layer 142 is laminated on the information ink layer 141, and a concealing layer 144 is further laminated thereon. On the other hand, since the varnish layer 142 is provided on the substrate sheet, the disguise information ink layer 143 is laminated on the varnish layer 142, and the concealing layer 144 is further laminated thereon, the peeling lottery is peeled off. It is also conceivable that irregularities due to the camouflaged information ink layer 143 are formed only in the concealing layer 144, and it is possible to recognize which lottery part is removed. Therefore, it is preferable to provide the masking layer 144 thickly, or to provide the camouflaged information ink layer 143 in the winning lot and the information ink layer 141 in the lottery ticket in order to align the unevenness that can be formed in the masking layer 144. At this time, when strong light is applied from the back surface of the substrate sheet, the lottery information included in the information ink layer 141 of the winning lot is such that all the lottery parts are displayed as shadows on the concealment layer 144 at least. The lottery information included in the information ink layer 141 of the lottery ticket may be different. For example, the information ink layer 141 of the winning lottery is set to “hits” made of characters, the information ink layer 141 of the lost lottery is made of a pattern, and the information ink layer 141 of the lost lottery is added to the camouflaged information ink layer 143 for the winning lottery. If the information ink layer 141 corresponding to the fake information ink layer 143 is provided in each of the lottery lottery, there is no difference in the unevenness that can be formed in the concealment layer 144 between the lottery and the lottery lottery, and strong from the back surface of the substrate sheet. Even if the light is applied, the letters “hit” appear as shadows on the concealment layer 144 in all the lots, making it difficult to determine which wins. There is no need to limit to these forms, and the information ink layer and the fake information ink layer may be designed in any way.
