Description

本発明は、複写防止機能を有する印刷物に関し、特に黒色トナーで個人情報等が印字される印刷物を複写した場合、複写された情報の判読が不可能であるか又は判読困難となる印刷物に関するものである。   The present invention relates to a printed matter having a copy prevention function, and more particularly to a printed matter in which, when a printed matter on which personal information or the like is printed with black toner is copied, the copied information is unreadable or difficult to read. is there.

従来から用紙に記録された情報の機密を守るための一つの手段として、静電複写装置により複写されたとしても複写情報が判読不可能か又は判読困難となるような複写不能用紙は知られている。この複写不能用紙は、白紙印刷面の全面又は所定の機密領域にセピア色等の光吸収性インキ印刷層を施したことを特徴としている。ところが、上記従来の複写不能用紙の場合には、複写濃度が薄い場合には、光吸収性インキ印刷層の部分の複写濃度も薄くなるため、記録された文字や図柄等の情報が判読可能となる場合がある。そうかといって、光吸収性インキ印刷層自体のセピア色等の濃度を濃くすれば、複写不能用紙に記録された情報が読みにくいという問題があった。そこで、上記の課題を解決した、複写不能用紙も提案されている（例えば、特許文献１参照）。これは、白紙印刷面の全面又は所定の機密領域に光吸収性インキ印刷層を施して、さらに、前記の光吸収性インキ印刷層は、網点による背景部と、背景部全面に散在しかつベタによる地紋とを含む版で単色により印刷されていることを特徴としている。上記構成によれば、光吸収性インキ印刷層の背景部は網点で構成されているのでその濃度は相対的に薄く、一方その地紋はベタ印刷であるからその濃度は相対的に濃いことになる。したがって、この背景部と地紋との面積比率を妥当な値とすることにより、複写不能用紙に記録された情報自体は読み易くすることを可能としている。
特開平６−７９９９２号公報 Conventionally, as a means for protecting the confidentiality of information recorded on paper, non-copyable paper is known in which copy information is unreadable or difficult to read even if copied by an electrostatic copying apparatus. Yes. This non-copyable paper is characterized in that a light-absorbing ink printing layer of sepia or the like is applied to the entire blank paper printing surface or a predetermined confidential area. However, in the case of the conventional non-copyable paper, when the copy density is low, the copy density of the light-absorbing ink printing layer is also reduced, so that information such as recorded characters and designs can be read. There is a case. However, if the light-absorbing ink printing layer itself has a high density such as sepia, there is a problem that information recorded on non-copyable paper is difficult to read. Therefore, a non-copyable paper that solves the above problem has also been proposed (see, for example, Patent Document 1). This is because the light-absorbing ink printing layer is applied to the entire surface of the blank paper printing surface or a predetermined confidential area, and the light-absorbing ink printing layer is scattered on the background portion by the halftone dots and the entire background portion and It is characterized by being printed in a single color on a plate containing a solid background pattern. According to the above configuration, since the background portion of the light-absorbing ink printing layer is composed of halftone dots, the density thereof is relatively thin, while the background pattern is solid printing, the density is relatively high. Become. Therefore, by setting the area ratio between the background portion and the background pattern to an appropriate value, the information recorded on the non-copyable paper can be easily read.
Japanese Patent Laid-Open No. 6-79992

上記の特許文献１に開示されている技術により、従来の欠点は改善されてはいる。しかし、このような複写不能用紙に黒色トナーで情報を印字する場合には、光吸収性インキには暗色が用いられており、印字も黒色であり、同じ暗色となるために色差が小さくなり、複写不能用紙に印字された情報が視認しにくいという問題がある。   The conventional drawbacks are improved by the technique disclosed in Patent Document 1 described above. However, when printing information with black toner on such non-copyable paper, a dark color is used for the light-absorbing ink, and the printing is also black, so the color difference is small because it is the same dark color, There is a problem that information printed on non-copyable paper is difficult to visually recognize.

本発明は、上記のような従来の問題点に鑑み、本発明の印刷物に黒色トナーで印字された記録情報自体が十分に読み取ることができ、かつ、この印刷物が比較的薄い濃度で複写された場合であっても、複写された記録情報が確実に判別不能または判別困難となる複写防止機能を有する印刷物を提供するものである。   In view of the above-described conventional problems, the present invention can sufficiently read the recorded information itself printed with black toner on the printed matter of the present invention, and the printed matter is copied at a relatively low density. Even in such a case, the present invention provides a printed matter having a copy prevention function that makes it difficult to discriminate or difficult to discriminate the recorded information.

上記課題を解決するために、請求項１記載の本発明は、基材上に黒色印刷層、パールインキ印刷層の順に積層されてなる複写不能領域を有することを特徴とするものである。   In order to solve the above-mentioned problem, the present invention according to claim 1 is characterized in that it has a non-copyable region in which a black printing layer and a pearl ink printing layer are laminated in this order on a substrate.

また、請求項２記載の本発明は、前記基材と前記黒色印刷層の間、もしくは前記黒色印刷層と前記パールインキ印刷層の間に下地印刷層を設けたことを特徴とするものである。   The invention according to claim 2 is characterized in that a base printing layer is provided between the base material and the black printing layer or between the black printing layer and the pearl ink printing layer. .

また、請求項３記載の本発明は、前記複写不能領域が、少なくとも情報印字部を有することを特徴とするものである。   The invention according to claim 3 is characterized in that the non-copyable area has at least an information printing portion.

請求項１に記載のように、本発明の印刷物は、基材上に黒色印刷層、パールインキ印刷層の順に積層されてなる複写不能領域を有することにより、該複写不能領域に黒色トナーで印字された情報は、パールインキ印刷層のパール光沢とのコントラストにより、明確に判読できる。これは、黒色トナーで印字された部分は光源から照射された光が吸収され反射光が殆どなくなるが、印字されていない部分は光源から照射された光がパールインキ印刷層で反射され、強い正反射光、あるいは弱い拡散反射光となって印字内容が見る人の目に入り、その反射率の差が大きくなるために、判読できるものである。一方、複写装置は被複写物に光を照射し、その拡散反射光で画像を取り込むために、前記印刷物を複写した場合、前記複写不能領域において、パールインキ印刷層の拡散反射光は弱くなるために、パールインキ印刷層の下に設けられた黒色印刷層の影響を受け、黒色に複写され、黒色トナーで印字されている部分の複写部との判別が不能または判別が困難となるものである。   As described in claim 1, the printed matter of the present invention has a non-copyable area formed by laminating a black print layer and a pearl ink print layer in this order on a base material, so that the non-copyable area is printed with black toner. The obtained information can be clearly read by the contrast with the pearl luster of the pearl ink printing layer. This is because the light emitted from the light source is absorbed and the reflected light is almost lost in the part printed with black toner, but the light emitted from the light source is reflected by the pearl ink printed layer in the part not printed. Since the printed contents enter the eyes of the viewer as reflected light or weak diffuse reflected light, and the difference in the reflectance increases, it is legible. On the other hand, since the copying apparatus irradiates the copy object with light and captures an image with the diffuse reflection light, when the print is copied, the diffuse reflection light of the pearl ink printing layer becomes weak in the non-copyable area. In addition, under the influence of the black printing layer provided under the pearl ink printing layer, it is impossible to distinguish or difficult to distinguish the portion copied by black and printed with black toner. .

以上のようにして、本発明の印刷物は複写防止効果を有し、黒色トナーで印字された情報を容易に入手できないという効果を奉する。   As described above, the printed matter of the present invention has an effect of preventing copying, and the effect that information printed with black toner cannot be easily obtained.

以下図面を用いて、本発明の実施形態について説明する。図１は本発明の印刷物の一実施形態である顧客リストの要部平面図である。図２は本発明の印刷物の複写不能領域を説明するためのものであり、図１のＡ−Ａ線断面図である。図３は本発明の印刷物の他の実施形態の図１のＡ−Ａ線相当部における断面図である。   Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a plan view of an essential part of a customer list which is an embodiment of a printed matter of the present invention. FIG. 2 is a cross-sectional view taken along the line AA of FIG. 1 for explaining a non-copyable region of the printed material of the present invention. FIG. 3 is a cross-sectional view taken along the line AA of FIG. 1 of another embodiment of the printed material of the present invention.

まず、図１および図２を用いて本発明の一実施形態について説明する。図１に示すように、本発明の印刷物１の一実施形態である顧客リスト１ａは、白紙（基材に対応）の印刷面に記録情報としてのリストが印刷されている。このリストは、予め、罫線が印刷されているとともに、その最上段が見出し欄２になっており、番号、顧客氏名、住所、商品等の見出し項目が印刷されている。そして、見出し項目番号の下部には“１"から始まる通し番号が印刷されている。見出し項目顧客氏名、住所の下部には複写不能領域３（図１の斜線部で示す）が設けられており、該複写不能領域３は、図２に示すように基材１０の上面に罫線等が印刷され、その上面に黒色印刷層１１、パールインキ印刷層１２の順に積層され、構成される。さらに、前記パールインキ印刷層１２の上面には、見出し項目顧客氏名の下部より山田太郎、鈴木花子等の具体的顧客氏名が黒色トナー１３で印字されており、また見出し項目住所の下部より各顧客氏名に対応する住所コードが黒色トナー１３で印字されている。一方、見出し項目商品等の下部には商品番号が基材１０の上面に黒色トナー１３で印字されている。もっとも、顧客氏名、住所、商品等の具体的印字は必ずしも黒色トナーによる印字だけでなく、種々の記録手段により記録されうる。   First, an embodiment of the present invention will be described with reference to FIGS. As shown in FIG. 1, the customer list 1a which is one embodiment of the printed matter 1 of the present invention has a list as recording information printed on a printing surface of a white paper (corresponding to a base material). This list is preprinted with ruled lines and has a heading column 2 at the top, and heading items such as numbers, customer names, addresses, and products are printed. A serial number starting from “1” is printed below the heading item number. A non-copyable area 3 (indicated by the hatched portion in FIG. 1) is provided below the heading item customer name and address. Is printed, and the black printing layer 11 and the pearl ink printing layer 12 are laminated in this order on the upper surface. Furthermore, on the upper surface of the pearl ink printing layer 12, specific customer names such as Taro Yamada and Hanako Suzuki are printed with black toner 13 from the bottom of the headline item customer name, and each customer is displayed from the bottom of the headline item address. An address code corresponding to the name is printed with black toner 13. On the other hand, the product number is printed with the black toner 13 on the upper surface of the base material 10 under the heading item product. However, specific printing of the customer name, address, product, etc. is not necessarily limited to black toner printing, but can be recorded by various recording means.

図２を用いて本発明の印刷物１の複写不能領域３について詳細に説明する。図２は図１のＡ−Ａ線断面図で複写不能領域３を示すものである。上質紙、中質紙、ＯＣＲ紙等を用いた基材１０の上面に黒色印刷層１１、パールインキ印刷層１２の順に積層されており、さらに、その上面に黒色トナー１３で顧客氏名、住所が印字されている。黒色印刷層１１はカーボンブラック等の墨インキ、もしくプロセスカラーインキで調色されたインキ等を用いて印刷される。パールインキ印刷層１２は一般に知られているマイカや酸化ケイ素、酸化アルミと酸化チタンや酸化鉄等の金属酸化物からなるパール顔料を含むインキで印刷され、オフセット、グラビア、シルクスクリーン等の印刷方式が利用できる。また、前記複写不能領域３において、基材１０と黒色印刷層１１との間、もしくは黒色印刷層１１とパールインキ印刷層１２との間に絵柄印刷層が設けられていてもよい。絵柄印刷層が黒色に馴染み絵柄として判読できないために複写不能領域３と絵柄印刷層の製版上の処理が不要となり好都合である。   The non-copyable area 3 of the printed material 1 of the present invention will be described in detail with reference to FIG. FIG. 2 is a cross-sectional view taken along line AA in FIG. A black printing layer 11 and a pearl ink printing layer 12 are laminated in this order on the upper surface of the base material 10 using high quality paper, medium quality paper, OCR paper or the like. Printed. The black printing layer 11 is printed using black ink such as carbon black, or ink that is toned with process color ink. The pearl ink printing layer 12 is printed with an ink containing a pearl pigment made of a metal oxide such as mica, silicon oxide, aluminum oxide and titanium oxide or iron oxide, which is generally known, and printing methods such as offset, gravure, silk screen, etc. Is available. In the non-copyable area 3, a pattern printing layer may be provided between the base material 10 and the black printing layer 11 or between the black printing layer 11 and the pearl ink printing layer 12. Since the pattern printing layer is familiar with black and cannot be read as a pattern, it is advantageous that processing on the plate making of the non-copyable area 3 and the pattern printing layer is unnecessary.

つぎに、図３を用いて、本発明の印刷物１の他の実施形態について説明する。図３は図１のＡ−Ａ線相当部における断面図であり、複写不能領域３を示すものである。基材２０の上面に下地印刷層２４を設けて、その上面に黒色印刷層２１、パールインキ印刷層２２が順に設けられ、さらに、その上面に黒色トナー２３で顧客氏名、住所が印字されている。下地印刷層２４を設けることにより、基材面の平滑性が増し、パールインキ印刷層２２の光輝性が一層向上し、黒色トナー２３とのコントラストが一層強いものとなり、黒色トナー２３で印字された情報が容易に判読できるようになる。該下地印刷層２４は、メジュームインキでも色インキでもよいが、メジュームインキの方が好適である。また、該下地印刷層２４は、パールインキ印刷層２２と黒色印刷層２１との間に設けてもよい。上記以外の各層は、前記の本発明の印刷物１の一実施形態と同じであり説明を省略する。   Next, another embodiment of the printed matter 1 of the present invention will be described with reference to FIG. FIG. 3 is a cross-sectional view taken along the line AA in FIG. A base printing layer 24 is provided on the upper surface of the substrate 20, a black printing layer 21 and a pearl ink printing layer 22 are sequentially provided on the upper surface, and a customer name and address are printed on the upper surface with black toner 23. . By providing the base printing layer 24, the smoothness of the substrate surface is increased, the glitter of the pearl ink printing layer 22 is further improved, the contrast with the black toner 23 is further increased, and printing is performed with the black toner 23. Information can be easily read. The underprint layer 24 may be a medium ink or a color ink, but a medium ink is more preferable. Further, the base printing layer 24 may be provided between the pearl ink printing layer 22 and the black printing layer 21. Each layer other than the above is the same as in the embodiment of the printed matter 1 of the present invention, and the description thereof is omitted.

顧客リスト、名簿等の情報漏洩防止が必要な書類に利用できる。   It can be used for documents that require information leakage prevention such as customer lists and rosters.
