【発明の詳細な説明】
本発明は複写機による偽造防止に好適する体裁
佳良な印刷物に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a good-looking printed matter suitable for preventing forgery by a copying machine.
有価証券等の重要書類がカラー複写機で偽造さ
れるのを防止するため、用紙表面に肉眼では識別
困難な「VOID」等の警告マークを印刷してお
き、複写機にかけたときに警告マークが背景部分
と区別されて視認できるようにしたものが既に提
案されている。 In order to prevent important documents such as securities from being forged using a color copying machine, a warning mark such as "VOID" that is difficult to see with the naked eye is printed on the surface of the paper so that the warning mark does not appear when the paper is run through the copying machine. There have already been proposals that allow the image to be visually distinguished from the background.
この種の先行技術として、背景を微細な網点で
構成し、警告マークを背景の倍の大きさの網点で
構成すると共に、肉眼では背景と警告マークが識
別されないようにこれらの両方の上飾りカムフラ
ージを設けた文書が知られている。 In this type of prior art, the background is made up of fine halftone dots, the warning mark is made up of halftone dots twice the size of the background, and the background is made of halftone dots that are twice the size of the background, and the background is made of halftone dots that are twice the size of the background. Documents with decorative camouflage are known.
しかして上記先行技術より以前にも、背景とは
大小差のある網点からなる警告マークを備えた文
書は考えられていたが、その場合多少注意して見
ると肉眼でも警告マークが容易に判読される欠点
があつた。 However, even before the above-mentioned prior art, documents with warning marks consisting of halftone dots of different sizes from the background had been considered, but in such cases, the warning marks could be easily read with the naked eye if one looked at them with some care. There were some drawbacks.
したがつてカムフラージを設けたことは警告マ
ークを識別しにくゝする点では有効であるが該文
書にも種々の不都合な点があつて広範な利用に供
しうるまでには至つていない。 Therefore, although the provision of camouflage is effective in making the warning mark difficult to identify, the document also has various disadvantages and has not been put to widespread use.
まず第一に、上記文書は警告マークと周囲の背
景及びカムフラージを混成マスクとしている点が
あげられる。混成マスクとしたことによつて印刷
前の版構成は当然乍ら網板一版であつて第１図に
示したように、印刷後用紙Ａの上面に施されたイ
ンキ層Ｂは一層一色刷となることが自明で、得ら
れた印刷物は大小の網点が配設されたのみの画一
的色彩をした無味乾燥なものとなる。 First of all, the document uses a hybrid mask of warning marks, surrounding background, and camouflage. By using a hybrid mask, the plate structure before printing is of course a mesh plate, and as shown in Figure 1, the ink layer B applied on the top surface of paper A after printing is a single-color printing layer. It is self-evident that the resulting prints will be bland and have a uniform color with only large and small halftone dots arranged thereon.
第二にこのような版構成によつて得られた印刷
物はコピー後の警告マークが明瞭に認められない
点において不利である。つまり同形の網点の組合
わせでは点の大小差を極端にするとカムフラージ
を設けても警告マークが肉眼で識別されてしまう
ので警告マークは背景に用いられるスクリーンの
倍数となる限定を加えたことによつてコピー後の
再現性に問題があるのと、警告マークと共にカム
フラージも一部残存するので見苦しくなるのを免
れない。 Secondly, printed matter obtained by such a plate structure is disadvantageous in that the warning mark after copying cannot be clearly recognized. In other words, in a combination of halftone dots of the same shape, if the size difference between the dots is extreme, the warning mark will be visible to the naked eye even if a camouflage is provided, so the warning mark must be a multiple of the screen used as the background. Therefore, there are problems with reproducibility after copying, and some of the camouflage remains along with the warning mark, making it unsightly.
第三にカムフラージは警告マークと一様平面上
の印刷となつているため自由なデザインとするこ
とができず装飾効果を発揮することは無理で印刷
物に美感を付与することが不可能に近くむしろ文
書の体裁を損ずることになり実用的でない欠点が
ある。 Thirdly, since camouflage is printed on a uniform plane with a warning mark, it is not possible to create a free design, and it is impossible to achieve a decorative effect, making it almost impossible to add a sense of beauty to printed matter. This has the disadvantage that it is impractical as it spoils the appearance of the document.
本発明は上述した先行技術の諸不利を解消した
印刷物を提供するものである。 The present invention provides a printed product that overcomes the disadvantages of the prior art described above.
以下本発明を図面について説明すると、第２図

で再現されない程度の薄色の透明性インキで重ね
刷りする。 The present invention will be explained below with reference to the drawings. As shown in Figs. 2 to 4, a latent image 2 indicating "COPY" is printed on a part of the surface of the paper 1 with 150 lines and 10% halftone dots. At the same time, a background 3 of the same density as the latent image 2 is simultaneously printed on the white area around the latent image using lines of 50 lines and 10% of each other. A decorative pattern 4 such as a colored pattern is overprinted with transparent ink of such a light color that it cannot be reproduced by copying.

（第６図）
第５図は潜像２を50線10％程度の万線によつて
印刷し、背景３を150線10％程度の網点で印刷し
た場合の他の実施態様を示したもので、こうする
ことによつて複写機にかけると潜像２は再現され
るのに対し背景３は再現されなくなるため両者に
濃度差が生じて潜像２が明瞭に識別される。 In this way, the fine constituent elements of latent image 2 are halftone dots of about 150 lines and 10%, while the fine constituent elements of background 3 around the latent image are about 50 lines and 10% of lines, and both are composed of The feature is that the child shapes are different. Therefore, if you carefully observe the latent image 2 before overprinting the decorative pattern 4, you can faintly identify the latent image 2, but after overprinting the decorative pattern 4, both are obscured and cannot be identified with the naked eye. In other words, it appears that only pattern 4 exists on the paper surface. This pattern 4 is of such a light color that it cannot be reproduced by copying, so when it is copied, the pattern 4 cannot be seen, whereas the background 3 printed with parallel lines is reproduced, and the latent image 2 is As a result of not being reproduced, the density difference between the background 3 and the latent image 2 becomes obvious, and the letters "COPY" are clearly recognized, making it obvious at a glance that it is a copy.
(Figure 6) Figure 5 shows another embodiment in which the latent image 2 is printed with 50 lines and 10% dots, and the background 3 is printed with 150 lines and 10% dots. By doing this, when the latent image 2 is applied to a copying machine, the latent image 2 is reproduced, but the background 3 is not reproduced, so that a difference in density occurs between the two, and the latent image 2 can be clearly identified.
つまり上記二つの実施態様に明らかなように本
発明は万線で印刷された背景若しくは潜像がコピ
ーすることによつて再現され、網点で印刷された
潜像若しくは背景が再現されない構成としたこと
を特徴とするものである。 In other words, as is clear from the above two embodiments, the present invention has a structure in which the background or latent image printed with parallel lines is reproduced by copying, and the latent image or background printed with halftone dots is not reproduced. It is characterized by this.
なお万線及び網点の構成子形状は図示したもの
に限定されない。 Note that the constituent shapes of the parallel lines and halftone dots are not limited to those shown.

飾模様４のデザイン、色あいともに自由な選択が
可能で印刷物に応じたパターンを形成すれば広範
な書類への適用がなされ実用上極めて有益なもの
となる。 That is, the present invention prints a latent image 2 made of fine constituent elements on the surface of the paper 1, and simultaneously prints a background 3 made of fine constituent elements having a different shape from the constituent elements on a white background area around the latent image. However, by overprinting the decorative pattern 4 on the upper surface of the latent image 2 with a thin transparent ink that cannot be reproduced by copying, the cross-sectional shape as shown in FIG. A one-color printing ink layer 3 is formed, and an ink layer 4 forming a decorative pattern is superposed on the upper surface thereof.
Therefore, the plate configuration before printing is such that the latent image and the decorative pattern are separate plates, which is a big difference from the prior art described above. As a result of such separate editions, the design and color tone of the decorative pattern 4 can be freely selected, and if a pattern is formed according to the printed material, it can be applied to a wide range of documents, making it extremely useful in practice.
そしてこのように任意に選択された装飾模様４
が再現性のある万線をも同化せしめる結果潜像と
背景は十分掩蔽されて両者は肉眼での識別が全く
困難になると共に薄色の装飾模様４は複写機にか
けると再現されなくなるのでコピー後においては
背景との濃度差顕著となつた潜像２が明瞭に現出
し識別されるわけである。 And the decorative pattern 4 arbitrarily selected in this way
As a result, the latent image and the background are sufficiently obscured, making it completely difficult to distinguish them with the naked eye, and the light-colored decorative pattern 4 cannot be reproduced when put on a copying machine, so it cannot be copied. Later, the latent image 2 with a noticeable difference in density from the background clearly appears and can be identified.
つまり潜像２と背景３を形成する微細構成子
は、先行技術のように同形の点の組合わせではな
く全く異図形とした点に独自性があり、微細構成
子相互の顕著な構造上の相違によつてコピー後の
両者の明暗の差が一目瞭然となるものである。 In other words, the fine constructs that form the latent image 2 and the background 3 are unique in that they are not a combination of points of the same shape as in the prior art, but are completely different shapes, and there is a remarkable structural difference between the fine constructs. Due to the difference, the difference in brightness between the two after copying becomes obvious at a glance.
上記のように構成子を異図形としたことによつ
て先行技術のような点の大小に拘束されず用紙１
の表面印刷を多様になしえると共に装飾模様４が
印刷物表面を美麗に体裁よく仕上げる結果、広範
な各種文書に供せられる著大な実益を具有する。 As mentioned above, by making the constructor into a different shape, paper 1 is not restricted by the size of the dots as in the prior art.
The decorative pattern 4 makes it possible to perform various types of surface printing, and as a result, the decorative pattern 4 finishes the surface of printed matter beautifully and neatly, and as a result, it has great practical benefits that can be applied to a wide variety of documents.
