Abstract

<P>PROBLEM TO BE SOLVED: To provide printed matter which enables easy determining of forgery by making a three-dimensional structure in a part of a pattern which creates a moire consisting of a curved image defining line. <P>SOLUTION: Forgery-proof printed matter comprises a group of image defining lines such as a first image defining line, a second image defining line, a third image defining line to an n-1th image defining line and an n-th image defining line. These image defining lines each have a specified image defining line width to be printed on the base. The first image defining line is formed of a straight line, and the n-th image defining line is formed of a specified curve. Further, the second image defining line, the third image defining line to the n-1th image defining line which are formed between the first image defining line and the n-th image defining line, are formed in such a shape that these image defining lines gradually get closer to the shape of a specified curve of the n-th image defining line from the straight line shape of the first image defining line. Thus, the image defining line of the image defining line group, is constituted of a low image defining line part and a high image defining line part, which differ in the height of protuberance from the base. In addition, the image defining line of the image defining line group forms an invisible image to the region composed of the low image defining line part on account of a height level difference from the region consisting of the high image defining line part. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

本発明は、銀行券、株券、債券等の有価証券、各種証明書及び重要書類等の偽造防止又は複製防止が必要と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 that requires prevention of counterfeiting or copying of banknotes, stock certificates, securities such as bonds, various certificates and important documents.

最近の複写機の著しい普及に伴い、銀行券、株券、債券等の有価証券、各種証明書及び重要書類等の貴重印刷物について、複写機による偽造、変造に対する防止策は重要な要素である。そうした複写機による複写物に対して、真正物であるか否かを判定する場合の有効な偽造防止策の一つにモアレによる模様がある。モアレによる模様は、一定の画線幅を有する直線や曲線が一定間隔で連続配列している印刷物上の模様と、複写時において複写機の走査入出力の走査線とが干渉し、干渉縞として発生するものである。   With the recent widespread use of copiers, measures to prevent counterfeiting and alteration by copiers are important factors for valuable securities such as banknotes, stock certificates, bonds and other securities, various certificates and important documents. One of the effective anti-counterfeiting measures for determining whether or not a copy made by such a copying machine is genuine is a moire pattern. The pattern by moire interferes with the pattern on the printed matter in which straight lines and curves having a constant line width are continuously arranged at regular intervals, and the scanning input / output scanning lines of the copier during copying cause interference fringes. It is what happens.

しかし最近のカラー複写機の著しい普及に伴い、偽造、変造による犯罪が増加する危険性を有しており、より一層効果の高い偽造、変造防止策として技術の開発が望まれていた。   However, with the recent widespread use of color copiers, there is a risk that crimes due to counterfeiting and alteration will increase, and the development of technology as a more effective forgery and alteration prevention measure has been desired.

前記偽造防止策としてのモアレによる模様を発生させる画線構成として、まず万線パターンによるものがある。例えば、実公平2−43747号公報によると、電子写真方式のカラー複写機コピーマシンによる複写偽造を防止するために、シート基材上に一つの色で万線パターンによる印刷層を形成し、更に該印刷層上に他の色で上記パターンと角度を変えて、万線パターン又は網点パターンによる印刷層を形成して、これをカラーコピーマシンによりコピーすると、カラーコピーマシンに用いられているレンズのレンズ収差により周辺部に歪みが生じるとともに、パターンを各々異なる色で構成しているので、色収差のために各色間でずれが生じ、本物の印刷物のモアレとは異なったモアレが発生するので、目視のみでカラーコピーマシンによる複写偽造のチェックができる複写偽造防止用印刷物が開示されている(例えば、特許文献1参照。)   As an image line configuration for generating a pattern due to moire as the anti-counterfeit measure, there is a line pattern first. For example, according to Japanese Utility Model Publication No. 2-43747, in order to prevent copying forgery by an electrophotographic color copying machine copy machine, a printed layer with a single line pattern is formed on a sheet base material in one color, A lens used in a color copy machine by forming a print layer with a line pattern or a halftone dot pattern on the print layer by changing the angle of the pattern with another color and copying it with a color copy machine. Because the lens aberration causes distortion in the peripheral part and the pattern is composed of different colors, the chromatic aberration causes a shift between the colors, resulting in a moiré that is different from the moiré of the actual printed matter. A copy-forgery-preventing printed matter that can be checked for copy-counterfeiting with a color copying machine only by visual observation is disclosed (for example, see Patent Document 1).

又、実開平1−36866号公報によると、隣り合う放射状線相互の間隔が略一定になるようにして、被画線形成物上の基準点から放射する多数本の放射状線を具備し、被画線形成物を複写した際にCCDセンサーの走査方向と平行になる部分に確実にモアレを発生させて複写物であることを特定できる画像形成体が開示されている(例えば、特許文献2参照。)   Further, according to Japanese Utility Model Laid-Open No. 1-38666, a plurality of radial lines radiating from a reference point on the object line formation are provided so that the distance between adjacent radial lines is substantially constant. There has been disclosed an image forming body that can identify a copy by reliably generating moire in a portion parallel to the scanning direction of the CCD sensor when the image forming object is copied (see, for example, Patent Document 2). .)

しかし、特許文献1及び2のいずれの考案も、万線パターンを利用しているので画線を構成する万線の角度に依存せざるを得ず、従って万線パターンの角度をかえた画線を多く組み合わせることが必要とされる。   However, since both devices of Patent Documents 1 and 2 use a line pattern, it is necessary to depend on the angle of the line constituting the line, and therefore the line with the angle of the line pattern changed. It is necessary to combine many.

そこで前述した角度に依存せずにモアレを発生させるものとして、同心円パターンを用いたものがある。例えば、実開平5−12173号公報には、被複写紙上に一定間隔を隔てた多数の同心円、あるいは多数の放射線よりなる背景部を印刷形成し、デジタルコピー機による複写時に上記背景部中のいずれかの部分がデジタルコピー機の読み取り方向に対してモアレを発生させる傾斜角度の網点あるいは線群とさせ、複写紙上にこの部分を被複写紙の背景部にはないモアレ発生部として現出させることによって、どのような読み取り方向から複写した場合でも被複写紙と同一の複写を行わせず、複写紙上に差異部を現出させて被複写紙との違いを明確とさせることが可能な複写偽造防止用の被複写紙が開示されている(例えば、特許文献3参照。)   Therefore, there is a technique using a concentric circle pattern as a technique for generating moire without depending on the angle described above. For example, in Japanese Utility Model Laid-Open No. 5-12173, a large number of concentric circles spaced apart from each other or a background portion made of a large amount of radiation is printed and formed on a copy paper. These portions are halftone dots or lines having an inclination angle that generates moire with respect to the reading direction of the digital copier, and this portion appears on the copy paper as a moire generation portion that is not in the background portion of the copy paper. Therefore, when copying from any reading direction, the same copy as the copy paper is not performed, and the difference can be made to appear on the copy paper to clarify the difference from the copy paper. A copy paper for preventing counterfeiting is disclosed (for example, see Patent Document 3).

また、特開平6−262893号公報には、基紙の表面に施された潜像又は背景のいずれか一方が150線10%程度の網点で形成され、他方が同心円パターンで形成され、同心円パターンの円形を構成する細線が1/10mmの太さを有し、かつ細線相互の間隔Sが1/2mm程度であり、潜像と背景は同色であり、同心円パターンを構成する細線は網点同様無数に存在して成る複写機適応型コピー偽造防止用紙が開示されている。この偽造防止用紙によると、同心円パターンを構成する細線は目立たないため、通常は網点との識別がつかず、肉眼で潜像と背景は一様平面に観察されるが、コピーをすると複写機の形式を問わず、また光の走査方向や用紙の置き方にも関係なく潜像が明瞭に現出するとともにモアレが発生することによって、潜像及びモアレが視認され、偽造防止となるものが開示されている(例えば、特許文献4参照。)   Japanese Patent Laid-Open No. 6-262893 discloses that either a latent image or background applied on the surface of a base paper is formed with a halftone dot of about 150% and 10%, and the other is formed with a concentric pattern. The fine lines constituting the pattern circle have a thickness of 1/10 mm, the distance S between the fine lines is about 1/2 mm, the latent image and the background are the same color, and the fine lines constituting the concentric circle pattern are halftone dots Similarly, an infinite number of copier-adaptive copy forgery prevention sheets are disclosed. According to this anti-counterfeit paper, the thin lines that make up the concentric pattern are not conspicuous, so it is usually impossible to distinguish them from halftone dots, and the latent image and background are observed on a flat surface with the naked eye. Regardless of the type of the image, the latent image appears clearly regardless of the light scanning direction and how the paper is placed, and the moire is generated, so that the latent image and the moire can be visually recognized to prevent forgery. (For example, refer to Patent Document 4)

また、本願出願人らも、特開平9−20061号公報記載の発明を提案している。この発明は、一定の画線幅の画線を有する複数の多角形に、多角形の辺を成す線分の外向には、多角形の線分と同一の画線幅の定量連続拡張した画線を施し、多角形の辺をなす線分の内向には、多角形の線分と同一の画線幅の収縮配列した画線を施し、多角形の辺をなす線分と、定量連続拡張した線画と、収縮配列した線画とが等間隔で配列されて成る線画の集合体で構成した複写防止模様の作成方法とその印刷物である(例えば、特許文献5参照。)   The applicants of the present application have also proposed the invention described in JP-A-9-20061. According to the present invention, a plurality of polygons having a line width of a certain line width are displayed on the outward direction of a line segment forming a side of the polygon in a quantitative continuous expansion with the same line width as that of the polygon line segment. A line is drawn, and the inward line segment forming the side of the polygon is given a contracted array with the same stroke width as the polygonal line segment, and the line segment forming the side of the polygon is quantitatively expanded continuously. And a printed product of a copy-preventing pattern composed of a collection of line drawings in which line drawings that have been contracted and line drawings that have been contracted are arranged at equal intervals (see, for example, Patent Document 5).

しかし、これらモアレによる模様を発生させる技術は、カラー複写機の入出力解像度によって効果が異なり、また最近では画像処理におけるフィルタリングによってモアレの発生を抑制することもできるため、モアレの発生が充分な偽造防止策となるとは言い難い状況である。   However, these moiré pattern generation techniques have different effects depending on the input / output resolution of the color copying machine, and recently, the generation of moiré can be suppressed by filtering in image processing. It is difficult to say that this is a preventive measure.

一方、特公昭56−19273号公報では、印刷物を傾けて観察して画像を現出するような方法として、印刷基材上に縦横の画線で構成される画像を凹版印刷することで印刷面を真上から観察した場合には確認できない潜像が角度を変えて観察すると顕像化される方法が開示されている(例えば、特許文献6参照。)   On the other hand, in Japanese Examined Patent Publication No. 56-19273, a printing surface is obtained by intaglio printing an image composed of vertical and horizontal lines on a printing substrate as a method of displaying an image by inclining the printed matter. A method has been disclosed in which a latent image that cannot be confirmed when viewed from directly above is visualized when viewed from a different angle (see, for example, Patent Document 6).

また、特開平5−339900号公報では、各種万線模様又はレリーフ模様、及びそれら双方の模様のいずれかの凹凸形状を有する素材と、素材の色及び無色透明以外の異なった他の色による一定な間隔を持つ各種万線画線又は網点画線、及びそれら双方のいずれかとを組み合わせることによって、ある特定の方向から観察するときにのみ、特定の文字、図柄などが認識できるようにした潜像模様形成体とその作製方法が開示されている(例えば、特許文献7参照)。   In Japanese Patent Laid-Open No. 5-339900, a material having various uneven shapes of various line patterns or relief patterns, and a pattern of both of them, and a constant by different colors other than the color of the material and colorless and transparent Latent image pattern that can recognize specific characters, designs, etc. only when observing from a specific direction by combining various line strokes or halftone strokes with various intervals, or both A formed body and a manufacturing method thereof are disclosed (for example, see Patent Document 7).

上述した従来の印刷物では、複写防止効果には優れる技術であるため、オリジナル印刷物の複写物は複写物か否か容易に判別できるが、オリジナル印刷物の真偽判別は拡大鏡等の簡易判別具が必要であった。また、これらモアレによる模様を発生させる技術は、カラー複写機の入出力解像度によって効果が異なっていた。   Since the conventional printed matter described above is a technology that has an excellent anti-copying effect, it can be easily determined whether the original printed matter is a copied matter. However, the authenticity of the original printed matter can be determined by a simple discriminator such as a magnifying glass. It was necessary. In addition, these techniques for generating patterns due to moire have different effects depending on the input / output resolution of the color copying machine.

また、最近では画像処理におけるフィルタリングによってモアレの発生を抑制することもできるため、モアレの発生が充分な偽造防止策になっていなかった。   In addition, recently, the generation of moire can be suppressed by filtering in image processing. Therefore, the generation of moire has not been a sufficient anti-counterfeit measure.

上記事情にかんがみ、オリジナル印刷物の複写物は複写物か否か容易に判別でき、オリジナル印刷物の真偽判別は拡大鏡等の簡易判別具を用いることなく判別可能な偽造防止印刷物が望まれている。本発明は、曲画線から成るモアレを発生させる模様の一部に、立体的な構成を設けることによって、オリジナル印刷物の複写物は複写物か否か容易に判別でき、オリジナル印刷物の真偽判別は拡大鏡等の簡易判別具を用いることなく判別可能な偽造防止印刷物を提供することを目的とする。   In view of the above circumstances, there is a demand for a forgery-preventing printed material that can easily determine whether a copy of the original printed material is a copied material, and can determine the authenticity of the original printed material without using a simple discriminating tool such as a magnifying glass. . According to the present invention, by providing a three-dimensional configuration to a part of a pattern that generates moiré composed of curved lines, it is possible to easily determine whether the copy of the original print is a copy or not. An object of the present invention is to provide an anti-counterfeit printed matter that can be discriminated without using a simple discriminating tool such as a magnifying glass.

以下、本発明の実施の形態1〜3による偽造防止印刷物について、本発明を実施するための最良の形態を図面を用いて説明する。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、特許請求の範囲に記載されている技術の範疇であれば、その他いろいろな実施の形態が含まれる。   Hereinafter, the best mode for carrying out the present invention will be described with reference to the drawings for a forgery-preventing printed material according to Embodiments 1 to 3 of the present invention. However, the present invention is not limited to the best mode for carrying out the invention described below, and various other embodiments are included within the scope of the technology described in the claims.

図1は、本発明の特徴である画線の立体的な構成が示された説明図である。図1(a)は印刷物1の平面図であり、印刷物1上に画線群2が形成されている。この画線群2は、等間隔で配置された画線幅の等しい複数の画線で構成され、図1(b)の正面図に示されるように、印刷物1における印刷面からの盛り上がりの高さの異なる低画線部3と高画線部4によって構成されている。これにより、図1(a)の平面図のように、印刷物1を真上から観察した場合、低画線部3と高画線部4との盛り上がりの高さは認識されない。すなわち、背景模様を構成する低画線部3に対し、高画線部4で構成する領域を不可視画像として施すことができる。   FIG. 1 is an explanatory diagram showing a three-dimensional structure of an image line, which is a feature of the present invention. FIG. 1A is a plan view of the printed matter 1, and an image line group 2 is formed on the printed matter 1. The image line group 2 is composed of a plurality of image lines with equal image line widths arranged at equal intervals, and as shown in the front view of FIG. It is composed of a low image line portion 3 and a high image line portion 4 having different sizes. As a result, as shown in the plan view of FIG. 1A, when the printed matter 1 is observed from directly above, the height of the swell of the low image portion 3 and the high image portion 4 is not recognized. In other words, the region formed by the high image portion 4 can be applied as an invisible image to the low image portion 3 configuring the background pattern.

図2は、図1に示された印刷物1の側面図である。図2に示されたように、観察者は任意の角度から成る視角5をもって観察した際、低画線部3と高画線部4の高さによって見え方の違いが現れる。低画線部3の視認長さ3aよりも高画線部4の視認長さ3bの方が長く見える。すなわち、図3の斜視図に示されたように、画線群2において、低画線部3の視認長さ3aよりも高画線部4の視認長さ3bの方が長く見えることから、低画線部3より高画線部4の方が高濃度で観察される。これにより、高画線部4で構成された領域から成る不可視画像が、斜めから観察することにより該領域が可視画像となって出現している。なお、画線群2における画線ピッチ並びに低画線部3と高画線部4の高さに何ら制限はないが、低画線部3と高画線部4の画線幅は200〜600μmで画線ピッチは300〜800μm、低画線部3の盛り高さは10〜30μmで高画線部4の盛り高さは20〜60μm程度が望ましい。低画線部3の盛りの高さと、高画線部4の盛り高さの差は特に限定されることはないが、10〜50μm程度が好ましい。   FIG. 2 is a side view of the printed matter 1 shown in FIG. As shown in FIG. 2, when an observer observes at a viewing angle 5 of an arbitrary angle, a difference in appearance appears depending on the height of the low image portion 3 and the high image portion 4. The viewing length 3b of the high image portion 4 looks longer than the viewing length 3a of the low image portion 3. That is, as shown in the perspective view of FIG. 3, in the image line group 2, the visual length 3 b of the high image portion 4 appears to be longer than the visual length 3 a of the low image portion 3. The high image area 4 is observed at a higher density than the low image area 3. As a result, the invisible image formed of the area formed by the high image line portion 4 appears as a visible image when observed from an oblique direction. There is no limitation on the line pitch in the image line group 2 and the heights of the low image area 3 and the high image area 4, but the image line widths of the low image area 3 and the high image area 4 are 200˜. It is desirable that the image line pitch is 300 to 800 μm at 600 μm, the height of the low image area 3 is 10 to 30 μm, and the height of the high image area 4 is about 20 to 60 μm. The difference between the height of the low image portion 3 and the height of the high image portion 4 is not particularly limited, but is preferably about 10 to 50 μm.

なお、図1に示された画線群2は、すべて直線形状で説明しているが、本発明の効果を奏するためには曲線形状が好ましい。また、印刷物1に用いられる印刷媒体は上質紙、コート紙等、何ら制限するものはなく、画線群2を印刷媒体に転写するための製版及び印刷方式も凹版印刷、スクリーン印刷等、素材を印刷面から盛り上がらせることが可能ならば何ら限定するものではない。   Note that the image line group 2 shown in FIG. 1 is all described in a linear shape, but a curved shape is preferable in order to achieve the effects of the present invention. In addition, the printing medium used for the printed material 1 is not limited in any way, such as high-quality paper, coated paper, and the plate making and printing method for transferring the image line group 2 to the printing medium are also intaglio printing, screen printing, etc. There is no limitation as long as it can be raised from the printed surface.

(1)実施の形態1
本発明の実施の形態1による偽造防止印刷物について説明する。
図4(a)は、本実施の形態1における印刷物を示した平面図である。基材に印刷される所定の画線幅からなる第1の画線、第2の画線、第3の画線・・第n−1の画線、第nの画線から成る画線群2によって形成される。印刷物1上の画線群2は等間隔又は略等間隔の低画線部3と高画線部4とで構成されており、低画線部3及び高画線部4は直線的な画線から曲線的へと徐々に近づき、変形されて形成された画線形状となっている。本実施の形態1において背景模様を構成する低画線部3に対し、高画線部4によって任意の図形、例えば図4(a)に示されるような「NPB」のアルファベットの文字を成した不可視画像として配置されている(本実施の形態1では、位置をわかり易くするため境界を点線で表現しているが、点線自体は印刷されるものではなく、境界を視認することができない)。この図4(a)に示された画線群2を、図2及び図3で示されたように斜めの角度で観察すると、図4(b)に示されるように、低画線部3と高画線部4の盛り高さの違いにより、高画線部4で構成される領域が可視画像となって出現する。
