【考案の詳細な説明】
[産業上の利用分野]
本考案は、複写機にかけると印影欄が黒ずんで
しまい印影のコピーが不能になるとともに用紙の
一部に複写物であることを知らしめる潜像を現出
させたコピー不能な印鑑登録証明用紙に関する。[Detailed description of the invention] [Industrial application field] This invention is designed to make it impossible to copy the seal impression because the seal impression field becomes dark when it is applied to a copying machine, and a part of the paper indicates that it is a copy. Concerning a seal registration certificate form that shows a latent image and cannot be copied.
[従来の技術]
印鑑登録証明書は、原本に押捺した朱印がコピ
ーで発行されているため印影欄に鮮明な黒色とな
つて表示される。したがつてこの証明書を不正に
入手した第三者が印影部分を切り貼りしてコピー
すると真正なものに酷似したものが得られ、コピ
ーの繰り返しにより際限なく偽造物を作製できる
という問題があつた。[Prior Art] Since a seal registration certificate is issued as a copy of the red stamp stamped on the original, it is displayed in a clear black color in the seal impression field. Therefore, if a third party who illegally obtained this certificate cut and pasted the seal part and copied it, he would be able to obtain something very similar to the genuine certificate, and by repeating the copying process, he could create an endless number of counterfeits. .
そこで複写機にかけたときに印影がコピーされ
ないようにするために、用紙表面の印影欄に金銀
などの金属色調光輝膜を形成したものがある(例
えば実開昭58−196172号公報参照)。 Therefore, in order to prevent the seal impression from being copied when the paper is used in a copying machine, there is a sheet of paper in which a metallic glitter film such as gold or silver is formed in the seal impression area on the surface of the paper (see, for example, Japanese Utility Model Application Publication No. 196172/1983).
上記用紙を印鑑登録証明書に使用すると光輝膜
上に印影は転写されるが、この証明書を原稿とし
て複写機にかけると光輝膜部分は真つ黒くなるの
で印影は識別できず、それゆえ複写機による悪用
は未然に防止できるというものである。 When the above paper is used as a seal registration certificate, the seal impression is transferred onto the glitter film, but when this certificate is used as a manuscript in a copying machine, the glitter film becomes completely black, making the seal imprint unrecognizable. This means that misuse of machines can be prevented.
[考案が解決しようとする課題]
上述の従来技術によると、光輝膜を形成するに
は金銀を箔押しするか光輝色を発現するインキを
用いて印刷する手段をとるが、前者の箔押し形成
によると製品が高価になるのに加え箔が付着しづ
らく、また印刷によると箔押しほどの光輝色が得
られないという不利と、いずれの手段も光輝膜に
よる鏡面反射を利用したものであるため光輝膜上
に半透明のマツトフイルムを被せると鏡面反射効
果がなくなつて容易にコピーされてしまうという
問題があつた。[Problem to be solved by the invention] According to the above-mentioned conventional technology, in order to form a glittering film, foil stamping of gold and silver or printing using an ink that develops a glittering color is used. In addition to making the product more expensive, the foil is difficult to adhere to, and printing does not produce the same bright color as foil stamping. There was a problem in that if a translucent matte film was used to cover the surface, the specular reflection effect would be lost and it would be easily copied.
しかして上述の技術によるとコピー不能となる
のは印影欄そのものであり、その他の紙面に記載
された事項の偽造を防止するためには警告文字な
どの潜像を別途設ける印刷手段を講じなければな
らなかつた。 However, according to the above-mentioned technology, it is the seal impression column itself that cannot be copied, and in order to prevent counterfeiting of other items written on the paper, it is necessary to take a printing method that separately creates a latent image such as a warning character. It didn't happen.
本考案はこのような従来の諸不利に鑑みてなさ
れたものであり、コピーをすると印影が黒ずんで
識別できなくなり、しかも用紙が偽造されたもの
であることを知らしめるようにした安価に提供で
きる印鑑登録証明用紙に関わるものである。 The present invention was devised in view of these conventional disadvantages, and it can be provided at a low cost by making it possible to make it known that the seal imprint is darkened and cannot be identified when it is copied, and that the paper is forged. This relates to seal registration certificate forms.
[課題を解決するための手段]
上記目的を達成するために本考案は次のような
技術手段をとるものであつて、すなわち基紙の表
面にセピア調色相のインキで施された背景と潜像
の一方が60線10%程度の万線で他方が150線10%
程度の網点で構成され、潜像とは離れた位置にあ
る表面の印影欄が、前記インキと同一インキによ
り線形模様からなる眩惑パターンと、150線70%
程度の網点からなる地部で構成されたコピー不能
な印鑑登録証明用紙である。[Means for Solving the Problem] In order to achieve the above object, the present invention takes the following technical means. One side of the latent image has 60 lines at 10%, and the other side has 150 lines at 10%.
The seal area on the surface, which is located away from the latent image and is composed of halftone dots, has a dazzling pattern consisting of a linear pattern with the same ink as the above, and a 150 line 70%
This is a seal registration certificate sheet that cannot be copied and is made up of halftone dots.
[作用]
上述の用紙からなる印鑑登録証明書は、登録さ
れた印影が印影欄に表示されるとともに氏名住
所・年月日等が表面の背景の該当欄に夫々記載さ
れる。このとき背景と潜像は微細な万線と網点に
よつて構成されているので薄いセピア調の表面と
して視認されるが肉眼で潜像は識別されない。[Operation] In the seal registration certificate made of the above-mentioned paper, the registered seal imprint is displayed in the seal imprint column, and the name, address, date, etc. are written in the corresponding columns on the background of the front surface. At this time, the background and the latent image are composed of fine parallel lines and halftone dots, so they are visually recognized as a pale sepia-toned surface, but the latent image is not discernible to the naked eye.
そして上記証明書を複写機にかけると万線は再
現されるが網点は再現されないので両者に濃淡の
差が生じ、それゆえ潜像は背景と明瞭に識別され
る。一方印影欄は、150線70%程度の網点と眩惑
パターで構成されているので通常も濃色に視認さ
れるが、複写機にかけると一層濃色に発現しこの
ため印影自体は印影欄に埋没したかたちになると
ともに印影の曲線部や縦横線部が眩惑パターンの
線形模様に干渉されるので識別が著しく困難とな
る。 Then, when the above-mentioned certificate is placed in a copying machine, the lines are reproduced, but the halftone dots are not reproduced, so there is a difference in shading between the two, and therefore the latent image can be clearly distinguished from the background. On the other hand, the seal impression field is composed of halftone dots of about 70% of 150 lines and a dazzling pattern, so it is normally visible as a dark color, but when it is applied to a copying machine, it appears even darker, and for this reason the seal itself is not visible in the seal impression field. It becomes extremely difficult to identify because the curved parts and vertical and horizontal line parts of the seal impression interfere with the linear pattern of the dazzling pattern.
[実施例]
印鑑登録証明用紙となる基紙1は、表面に背景
2と、「コピー」と表示した潜像5がセピア調色
相インキで施されている。背景2は60線10%の万
線3で構成され、潜像5は150線10%の網点4で

線形模様からなる眩惑パターン7、及びこの眩惑
パターンの線間隔である地部8を150線70%の網
点で同時印刷してあり、したがつて印影欄6はセ
ピア調が頗る濃色に認められる。[Example] A base paper 1 serving as a seal registration certificate paper has a background 2 and a latent image 5 indicating "copy" on the surface thereof using sepia tone ink. The background 2 is composed of 60 lines and 10% lines 3, and the latent image 5 is composed of 150 lines and 10% halftone dots 4. Therefore, the lines 3 are reproduced by the copying machine, but the halftone dots 4 are not reproduced. However, because the lines and halftone dots have minute shapes, the latent image 5 cannot usually be discerned with the naked eye, and only when a copy is made. The latent image 5 has a light color and can be distinguished from the background composed of parallel lines, which is reproduced in a dark color. In the seal impression field 6 located at the upper left of the figure, a dazzling pattern 7 consisting of a linear pattern combining wavy curves and straight lines in the vertical and horizontal directions, and a background with the line spacing of this dazzling pattern are created using the same ink as the above-mentioned ink. Part 8 was printed at the same time with 150 lines and 70% halftone dots, so the seal impression section 6 appears to be a deep color with a pronounced sepia tone.
そしてこのような構成とした印影欄6に登録さ
れた印影9が転写されると該印影は黒く鮮明に視
認されるが、これをさらにコピーすると濃色の眩
惑パターン7は黒く発色するので黒の印影は干渉
を受けて判読が極めて困難になるとともに印影の
修正も不可能となる。 When the seal imprint 9 registered in the imprint column 6 configured as above is transferred, the imprint is black and clearly visible, but when this is further copied, the dark dazzling pattern 7 becomes black. The seal impression is interfered with, making it extremely difficult to read and making it impossible to correct the seal impression.
なお上記実施例とは逆に、背景2を網点で、潜
像5を万線で形成してもよい。 Note that, contrary to the above embodiment, the background 2 may be formed by halftone dots, and the latent image 5 may be formed by parallel lines.
[考案の効果] 本考案は以下のような特有の効果を奏する。[Effect of the idea] The present invention has the following unique effects.
(1) 本案用紙を複写機にかけると背景と潜像の区
別が判然とするので偽造物であることが一目瞭
然になるとともにコピーをすると黒く発色する
印影欄によつて印影の判読が困難となるので、
印影部の削除・切り貼りによる悪用が防止され
るという一石二鳥的効果が得られる。(1) When the original paper is run through a copying machine, the background and latent image are clearly distinguishable, making it obvious that it is a forgery, and when it is copied, it becomes difficult to decipher the seal impression due to the black seal area. So,
This has the effect of killing two birds with one stone by preventing misuse by deleting or cutting and pasting the seal impression.
(2) 印影欄の眩惑パターンと地部は背景と同時に
印刷されるので本案は容易に作製され、工程が
少なく安価に得られる。(2) Since the dazzling pattern and background of the seal area are printed at the same time as the background, the main design is easy to produce, requires few steps, and can be obtained at low cost.
(3) 印影欄はセピア調色相のインキを用いて通常
の印刷を施したものであるから、従来の鏡面反
射を利用したものと異なつて印影が鮮明に視認
されるが、マツトフイルムを用いてもコピー不
能効果に何ら支障を生じない。すなわちセピア
調色相はコピーでは黒く発色するという原理を
利用しており、これは人間の目の色感度と複写
機の色感度との相違に基づくからである。(3) The seal area is printed using normal sepia-toned ink, so the seal impression is clearly visible, unlike the conventional one that uses specular reflection. However, there is no problem with the non-copyable effect. That is, the sepia tone hue utilizes the principle that the color appears black in a copy, and this is based on the difference between the color sensitivity of the human eye and the color sensitivity of a copying machine.
(4) コピーされた結果ある程度印影が再現されて
も眩惑パターンの線形模様が印影の曲線部及び
直線部に干渉するためあらゆる印影の判読が困
難となる。(4) Even if the seal impression is reproduced to some extent as a result of copying, the linear pattern of the dazzling pattern interferes with the curved and straight parts of the seal impression, making it difficult to decipher any seal impression.
