Description

本発明は、銀行券、株券、有価証券、通行券、パスポート、商品券又はカード等の偽造防止をする必要性のある貴重印刷物に適用される偽造防止印刷物に関するものである。   The present invention relates to an anti-counterfeit printed matter applied to a valuable printed matter that needs to be counterfeited such as a banknote, a stock certificate, a securities, a passport, a passport, a gift certificate or a card.

銀行券、株券、有価証券、通行券、パスポート、商品券、カード、印紙類、商品タグ、切符、定期券等の通行券、有料道路等の回数券又は各種チケット等の貴重印刷物は、その性質上、偽造や改ざんされないことが要求される。印刷による偽造防止技術としては、赤外線吸収インキ、赤外線ペアインキ、磁性インキ又は磁性ペアインキ等による印刷物が挙げられる。また、用紙については、紙基材の透過光強度を変化させたマーク等が挙げられる。   Banknotes, stock certificates, securities, passports, passports, gift certificates, cards, stamps, product tags, tickets, pass tickets such as commuter passes, toll road tickets, etc. In addition, it is required not to be counterfeited or tampered with. Examples of the anti-counterfeiting technology by printing include printed matter using infrared absorbing ink, infrared pair ink, magnetic ink, magnetic pair ink, or the like. As for the paper, a mark or the like in which the transmitted light intensity of the paper base material is changed can be used.

例えば、赤外線ペアインキによる印刷物としては、コート紙に印刷層を形成し、印刷層はカーボンブラックを使用した墨インキで印刷される第1の領域と、藍インキ、黄インキ及び紅インキを含有した墨インキで印刷される第2の領域で形成され、この印刷物は、通常光のもとでは第1の領域及び第2の領域は同色に見えるが、赤外線表示装置で観察した場合に第1の領域のみ確認できる技術が開示されている(例えば、特許文献1参照)。   For example, as a printed matter using infrared pair ink, a printed layer is formed on coated paper, and the printed layer is a first region printed with black ink using carbon black, and black ink containing indigo ink, yellow ink, and red ink. The printed area is formed of a second area that is printed with ink, and the printed material is usually the same color in the first area and the second area under normal light, but the first area when viewed with an infrared display device. A technique that can be confirmed only is disclosed (for example, see Patent Document 1).

また、磁性インキによる印刷物としては、情報が記録される記録部と、この記録部に対する情報の記録又は再生に関する情報が記録された複数の磁性バーコードとを有し、この磁性バーコードは相互に異なる磁気量を持つ記録媒体であって、この磁性バーコードは、異なる磁性インク量又は磁性材質から成るバーで構成されていることを特徴とする記録媒体が開示されている(例えば、特許文献2参照)。   Further, the printed matter using magnetic ink has a recording portion on which information is recorded and a plurality of magnetic barcodes on which information on recording or reproduction of information with respect to the recording portion is recorded. There is disclosed a recording medium having different magnetic amounts, wherein the magnetic barcode is composed of bars made of different magnetic ink amounts or magnetic materials (for example, Patent Document 2). reference).

また、磁性ペアインキによる印刷物としては、図柄の少なくとも一部に、少なくとも第1の印刷画像と第2の印刷画像を含む印刷物であって、第1の印刷画像が紫外線領域から可視光領域にかけて吸収帯域を有し、赤外線領域で光を透過する特性を有する磁性材料が含有された第1の磁性インキ組成物によって印刷され、第2の印刷画像が第1の印刷画像とは磁性特性及び光学特性が異なる第2の磁性インキ組成物によって印刷されて成る磁性印刷物が開示されている(例えば、特許文献3参照)。   Further, the printed matter using magnetic pair ink is a printed matter including at least a first printed image and a second printed image in at least a part of the design, and the first printed image has an absorption band from the ultraviolet region to the visible light region. And the second printed image is different from the first printed image in terms of magnetic properties and optical properties, and is printed with a first magnetic ink composition containing a magnetic material having a property of transmitting light in the infrared region. A magnetic printed matter that is printed with a different second magnetic ink composition is disclosed (for example, see Patent Document 3).

また、機械による読み取り及び真偽判別を目的として、紙基材の透過光強度を変化させたマークを形成し、読み取る技術及び偽造防止用紙が開示されている(例えば、特許文献4参照)。   Further, for the purpose of machine reading and authenticity determination, a technique for forming and reading a mark in which the transmitted light intensity of a paper substrate is changed and reading is disclosed (for example, see Patent Document 4).

このように、従来は印刷で形成する機械読み取り方法として、基材に磁性ペアインキ又は赤外線ペアインキで印刷し、それを機械読み取りする技術はあった。一方、用紙で形成する機械読み取り方法としては、紙基材の透過光強度を変化させたマークを形成し読み取る技術があった。   Thus, conventionally, as a machine reading method formed by printing, there has been a technique of printing on a substrate with a magnetic pair ink or an infrared pair ink and machine reading it. On the other hand, as a machine reading method for forming on a sheet, there is a technique for forming and reading a mark in which the transmitted light intensity of a paper substrate is changed.

特開2003−302519号は、赤外吸収特性の異なる印刷インキによって印刷された印刷領域の読み取りでの真偽判別技術であり、磁気センサの読み取りについては、記載されていなかった。また、特開2005−268655号公報では、赤外線領域で光を透過する特性を有する磁性材料が含有された第1の磁性インキ組成物によって形成された領域は、赤外線センサでの機械読み取りに有効な信号を得ることができず、この領域で有効な信号を有する偽造防止印刷物が求められてきた。さらに、特開2001−10197号公報は、紙基材の透過光強度を変化させたマークのみの読み取りによって真偽判別を行う技術であり、磁気センサの読み取りについては記載されていなかった。   Japanese Patent Application Laid-Open No. 2003-302519 is a technique for determining authenticity in reading a print area printed with printing inks having different infrared absorption characteristics, and does not describe reading of a magnetic sensor. In JP 2005-268655 A, an area formed by the first magnetic ink composition containing a magnetic material having a property of transmitting light in the infrared region is effective for machine reading by an infrared sensor. There has been a demand for anti-counterfeit printed matter that cannot obtain a signal and has an effective signal in this region. Furthermore, Japanese Patent Application Laid-Open No. 2001-10197 is a technique for performing authenticity determination by reading only a mark in which the transmitted light intensity of a paper substrate is changed, and does not describe reading of a magnetic sensor.

また、特開2002−302519号公報、特開昭63−223892号公報及び一般的な磁性材料は、可視及び赤外線領域で光を吸収する特性を有しているため、前述したようなマーク上に印刷した場合には、読み取りを阻害するという問題があった。   In addition, since JP 2002-302519 A, JP 63-238992 A, and general magnetic materials have a characteristic of absorbing light in the visible and infrared regions, the above-described marks are used. In the case of printing, there is a problem that reading is obstructed.

本発明は、前述した問題点を解決することを目的としたもので、紙基材の一部にマークを有し、マークと、マークが施されていない領域は赤外線透過光の強度が異なり、マーク上に印刷模様を施した場合でも、赤外線領域でマークを読み取る際に、マーク上に形成した印刷領域に読み取りを阻害されることなく、マークの読み取りが可能であり、更にマーク上に施された印刷が、磁気センサによって機械読み取り可能な新たな偽造防止印刷物を提案するものである。   The present invention aims to solve the above-mentioned problems, has a mark on a part of the paper substrate, the mark and the area where the mark is not applied, the intensity of infrared transmitted light is different, Even when a printed pattern is applied on the mark, the mark can be read without being obstructed by the printed area formed on the mark when the mark is read in the infrared region. The proposed printing is a new anti-counterfeit printed matter that can be machine-readable by a magnetic sensor.

本発明は、紙基材の一部にマークを有し、前記マークと前記マークが施されていない領域は赤外線透過光の強度が異なり、前記マーク上の少なくとも一部に印刷模様が形成され、前記印刷模様は、赤外線透過磁性インキ組成物によって前記紙基材の少なくとも一方の面に形成されることを特徴とする偽造防止印刷物である。 The present invention has a mark on a part of the paper substrate, the mark and the area where the mark is not applied have different infrared transmitted light intensity, and a printed pattern is formed on at least a part of the mark, The printed pattern is an anti-counterfeit printed matter formed on at least one surface of the paper base material by an infrared transmitting magnetic ink composition.

また、本発明は、紙基材の一部にマークを有し、前記マークと前記マークが施されていない領域は、赤外線透過光の強度が異なり、前記マーク上の少なくとも一部に第1の領域と第2の領域から成る印刷模様が形成され、前記印刷模様は、前記紙基材の少なくとも一方の面に形成され、前記マーク上には、少なくとも一部の前記第1の領域及び少なくとも一部の第2の領域が形成され、前記第1の領域は、赤外線透過磁性インキ組成物によって形成され、前記第2の領域は、磁性材料を含有しない赤外線透過インキ組成物又は前記第1の領域を形成する赤外線透過磁性インキ組成物に混合された磁性材料と種類及び/又は配合量が異なっている赤外線透過磁性インキ組成物によって形成されることを特徴とする偽造防止印刷物である。 Further, the present invention has a mark on a part of the paper base material, and the mark and the region where the mark is not provided have different infrared transmitted light intensities. A printed pattern composed of a region and a second region is formed, and the printed pattern is formed on at least one surface of the paper base, and at least a part of the first region and at least one of the marks are formed on the mark. A second region is formed, the first region is formed by an infrared transmitting magnetic ink composition, and the second region is an infrared transmitting ink composition that does not contain a magnetic material or the first region. The anti-counterfeit printed matter is formed of an infrared transmitting magnetic ink composition that is different in type and / or blending amount from the magnetic material mixed in the infrared transmitting magnetic ink composition.

また、本発明は、前記第2の領域を形成する前記磁性材料を含有しない赤外線透過インキ組成物又は赤外線透過磁性インキ組成物と、前記第1の領域を形成する赤外線透過磁性インキ組成物は、200〜700nmの光の波長領域において、反射特性及び/又は透過特性が相互に異なっていることを特徴とする偽造防止印刷物である。 Further, the present invention provides an infrared transmitting ink composition or an infrared transmitting magnetic ink composition that does not contain the magnetic material forming the second region, and an infrared transmitting magnetic ink composition that forms the first region, In the wavelength region of light of 200 to 700 nm, the anti-counterfeit printed matter is characterized in that reflection characteristics and / or transmission characteristics are different from each other.

また、本発明は、前記第2の領域を形成する前記磁性材料を含有しない赤外線透過インキ組成物又は赤外線透過磁性インキ組成物と、前記第1の領域を形成する赤外線透過磁性インキ組成物は、200〜700nmの波長領域の光を照射したときの発光の有無、発光波長及び残光波長の少なくとも一つが相互に異なっていることを特徴とする偽造防止印刷物である。 Further, the present invention provides an infrared transmitting ink composition or an infrared transmitting magnetic ink composition that does not contain the magnetic material forming the second region, and an infrared transmitting magnetic ink composition that forms the first region, An anti-counterfeit printed matter characterized in that at least one of the presence / absence of light emission, light emission wavelength and afterglow wavelength when irradiated with light in a wavelength region of 200 to 700 nm is different from each other.

また、本発明は、前記マークがすき入れであることを特徴とする偽造防止印刷物である。 In addition, the present invention is the anti-counterfeit printed matter, wherein the mark is a crease.

紙基材の一部にマークを有し、マークと、マークが施されていない領域は赤外線透過光の強度が異なり、マーク上に印刷模様を施した場合でも、赤外線領域でマークを読み取ることが可能であり、また、印刷模様を磁気センサによって検出可能である。よって、ある特定の領域内でマークの機械読み取り及び印刷模様の機械読み取りができるため、少なくとも二つの真偽判別が可能となり真偽判別効果に優れる偽造防止印刷物が得られる。さらに、マーク上に印刷模様を形成することでマークを隠蔽することも可能となるため、秘匿性を高めることができる。   There is a mark on a part of the paper base, and the mark and the unmarked area have different infrared transmitted light intensity, and even when a printed pattern is applied on the mark, the mark can be read in the infrared area. The printed pattern can be detected by a magnetic sensor. Accordingly, since the mark can be mechanically read and the printed pattern can be mechanically read within a specific area, at least two authenticity determinations can be made, and a forgery-preventing printed matter having an excellent authenticity determination effect can be obtained. Furthermore, since the mark can be concealed by forming a printed pattern on the mark, the secrecy can be improved.

また、紙基材に、その紙基材とは透過光量の異なるマークを有し、マーク上の表面及び/又は裏面に印刷模様を施し、マーク上に形成する印刷模様を第1の領域と第2の領域によって形成し、第1の領域と第2の領域では磁性特性及び/又は光学特性を異ならせることによって、複雑な磁気信号又は光学信号が得られ、偽造防止効果が優れる印刷物となる。   Further, the paper base material has a mark having a transmitted light amount different from that of the paper base material, a printed pattern is applied to the front surface and / or the back surface of the mark, and the printed pattern to be formed on the mark is defined as the first region and the first region. By forming the first region and the second region with different magnetic characteristics and / or optical characteristics, a complicated magnetic signal or optical signal can be obtained, and the printed matter has an excellent anti-counterfeit effect.

さらに、本発明の偽造防止印刷物は、プリンタ又は複写機等によって印刷模様を形成して偽造を試みた場合、赤外線領域でのマークの読み取りが困難となるため、偽造防止効果に優れる。   Furthermore, the anti-counterfeit printed matter of the present invention is excellent in the anti-counterfeiting effect because it becomes difficult to read the mark in the infrared region when a forgery is attempted by forming a printed pattern with a printer or a copying machine.

本発明を実施するための最良の形態を図面を参照して説明する。しかしながら、本発明は、以下に述べる実施するための最良の形態に限定されるものではなく、特許請求の範囲記載における技術的思想の範囲内であれば、その他のいろいろな実施の形態が含まれる。   The best mode for carrying out the present invention will be described with reference to the drawings. However, the present invention is not limited to the best mode for carrying out the invention described below, and includes various other embodiments within the scope of the technical idea described in the scope of claims. .

紙基材1の一部にマーク2を有し、マーク2と、マーク2が施されていない紙基材1の領域は、赤外線透過光の強度が異なる。このマーク2は、すき入れによるマーク、ワニス又はメジューム等の透明樹脂によって形成されるマークが挙げられる。   A portion of the paper substrate 1 has a mark 2, and the region of the paper substrate 1 where the mark 2 and the mark 2 are not applied has different intensities of infrared transmitted light. Examples of the mark 2 include a mark formed by filling, and a mark formed of a transparent resin such as varnish or medium.

すき入れマークとは、用紙の製造工程でパルプ繊維材が水素結合する以前に、パルプ繊維材から成る紙料に、規則的な外力を加えることによって得られる紙層の凹凸や疎密から成る三次元的な紙層構造を意味している。また、すき入れには、その透過光強度が周辺よりも強い白すかしと、その透過光強度が周辺よりも弱い黒すかしがあるが、本発明のすき入れによるマークとしては、白すかし又は黒すかしのいずれのすかしを用いてもよく、それぞれのマークがマークごとに均質な透過光強度を持つように、用紙の所定の位置にすかしによるマークを形成すればよい。この時、マークごとに均質な透過光強度を持った互いに透過光強度が異なる複数のすかしによるマークの間隔をあけて並置した構成としてもよいし、マークごとに均質な透過光強度を持った互いに透過光強度が異なる複数のすかしによるマークの間隔をあけることなく隣接するように構成してもよく、すかしによるマークの構成に関して特に制約はない。   A crease mark is a three-dimensional structure consisting of irregularities and denseness of the paper layer obtained by applying regular external force to the pulp fiber material before hydrogen bonding of the pulp fiber material in the paper manufacturing process. This means a typical paper layer structure. In addition, there are white watermarks whose transmitted light intensity is stronger than the surroundings and black watermarks whose transmitted light intensity is weaker than the surroundings. However, the marks according to the present invention include white watermarks. Alternatively, a black watermark may be used, and a mark by a watermark may be formed at a predetermined position on the sheet so that each mark has a uniform transmitted light intensity for each mark. At this time, the marks may be arranged side by side with a plurality of watermarks having different transmitted light intensities with uniform transmitted light intensity for each mark, or each mark has a uniform transmitted light intensity. A plurality of watermarks having different transmitted light intensities may be adjacent to each other without leaving an interval, and there is no particular limitation on the mark configuration.

ワニス又はメジューム等の透明樹脂によって形成されるマークは、凹版印刷、オフセット印刷、グラビア印刷、インクジェット又はレーザプリンタ等、特に限定されるものではない。   The mark formed of a transparent resin such as varnish or medium is not particularly limited, such as intaglio printing, offset printing, gravure printing, inkjet or laser printer.

なお、本発明のマークには、バーコード及び二次元バーコード等のコード情報並びに幾何学模様、文字、記号及び図形等のデザインを用いることができるが、実際に機械による読み取りに用いるマークについては、安定した読み取り精度を確保するために、機械による読み取り位置に若干の変動があったとしてもマーク幅、マーク位置、マーク間隔及び赤外線透過光強度等に関して変動を少なくできるように、マークごとに均質な赤外線透過光強度を持った簡単なデザインのマークを用いることが好ましい。   For the marks of the present invention, code information such as barcodes and two-dimensional barcodes and designs such as geometric patterns, characters, symbols and figures can be used. In order to ensure stable reading accuracy, even if there is a slight change in the reading position by the machine, it is uniform for each mark so that fluctuations in the mark width, mark position, mark interval, infrared transmitted light intensity, etc. can be reduced It is preferable to use a mark with a simple design having a high infrared transmission light intensity.

As shown in FIG. 1 (d), the area of the printed pattern 3 has a high magnetic intensity, and a waveform P1 is obtained, so that the printed pattern 3 can be read.

(Forgery prevention printed matter A2)
FIG. 2A shows a forgery prevention printed matter A2. FIG. 2B is a cross-sectional view taken along the line XX ′ of the anti-counterfeit printed matter A2 of FIG. As shown in FIGS. 2A and 2B, a mark 2 having a transmitted light intensity higher than that of the paper base material 1 is provided on a part of the paper base material 1, and the printed pattern 3 is formed on the mark 2. It is formed. The printed pattern 3 includes a first area 3a and a second area 3b. The first region 3a is printed with an infrared transmitting magnetic ink composition, and the second region 3b is mixed with an infrared transmitting ink composition containing no magnetic material or an infrared transmitting magnetic ink composition forming the first region 3a. The printed magnetic material is printed with an infrared transmitting magnetic ink composition containing different kinds of magnetic materials and / or different amounts of magnetic materials.

第2の領域3bを形成する赤外線透過磁性インキ組成物は、磁性材料の種類及び/又は配合量を異ならせた磁性材料を配合することができる。本発明はこれに限定されることなく、本発明における磁性特性が異なるとは、磁性材料の有無、同一の磁性材料の配合量の多少及び異なった種類の磁性材料の配合量の多少の少なくとも一つによって形成され、初期透磁率、残留磁束密度、保持力及びキュリー温度等の少なくとも一つの特性が異なり、公知の磁気センサの読み取りによって、磁気検知電圧又は磁気検知波形の差異として特徴量を有効に検出可能な特性を有する。さらに、上記複数の磁性特性の違いにより、検出感度が異なるセンサを組み合わせた場合に、第1のセンサで検出された磁気検出波形形状と、第2のセンサで検出された磁気検出波形形状を大きく変化させる等、特徴的な変化を形成できる。   The infrared transmitting magnetic ink composition forming the second region 3b can be blended with a magnetic material in which the kind and / or blending amount of the magnetic material is different. The present invention is not limited to this, and that the magnetic properties in the present invention are different means that at least one of the presence / absence of a magnetic material, the blending amount of the same magnetic material, and the blending amount of different kinds of magnetic materials is at least one. The characteristic quantity is effectively used as a difference in the magnetic detection voltage or magnetic detection waveform by reading a known magnetic sensor by at least one characteristic such as initial magnetic permeability, residual magnetic flux density, coercive force, and Curie temperature. Has detectable characteristics.
