Abstract

<P>PROBLEM TO BE SOLVED: To prepare an uncopiable document, so as to prevent the documents having important highly-classified information from being copied by a copying machine and flowing out easily. <P>SOLUTION: A black camouflage pattern (2) is printed in overlap on paper (3) dyed or printed black and a fluorescent ink (1) coloring under black light is printed thereon. In this way, the paper having a sectional structure shown in the figure is prepared. The highly-classified information is printed out on this paper. The black camouflage pattern is present on the black paper and thus it is difficult to read the black print by the naked eye. When the black light is shone, the whole fluorescent surface is made to color and the print can be read, since it holds down the fluorescence and does not color. A copy comes out only to be black. <P>COPYRIGHT: (C)2004,JPO&NCIPI

【発明の属する技術分野】
この発明は、用紙の構造及び書類の製作方法に関する物である。
【0002】
【従来の技術】
大切な情報がコピー機により複写され、簡単に流出するのを防ぐために、コピーすれば複写物に警告文字が出てくる物がある。
【0003】
また、表面を鏡のように加工して光の乱反射を応用しコピーが真っ黒に写るようにした物もある。
【発明が解決しようとする課題】
コピーすれば複写物に警告文字が出てくる物では、コピーは防げない。
【0004】
表面を鏡のように加工して光の乱反射を応用しコピーが真っ黒に写るようにした物は、プリンターの熱によりカールするので取り扱い難い。
【0005】
また、ギラギラして文字が判読し難い。
【0006】
【課題を解決するための手段】
黒色に染色又は印刷した用紙(3)の上に、黒色の迷彩模様(2)を重ねて印刷し、その上からブラックライトで発色する蛍光面を持つ構造にする。
【0007】
この用紙に、極秘情報等を黒色でプリントアウトする。
【0008】
肉眼では黒い用紙の上に黒い迷彩模様が有り、黒い印字の判読は困難である。
【0009】
ブラックライトを照らすと、蛍光面全体が発色するが、印字は蛍光を抑えて発色しないので鮮明に判読できる。
【0010】
コピーは真っ黒にしか写らない。
【発明の実施の形態】
用紙を全面黒色に染色又は印刷する。
【0011】
用紙の黒色と後の印字の黒色とでは、少し色に差が出来てしまうので、よりいっそう判読しづらくするために、その上から黒色で乱数や地紋等の迷彩を重ねて印刷する。
【0012】
その上から、ブラックライトで発色する無色の蛍光インキで全面を印刷する。
【0013】
こうして出来た本発明のコピー不可用紙にプリンターで極秘情報等を黒色でプリントアウトし、コピー不可書類を製作する。
【0014】
または、通常の用紙の極秘情報等の書類を原稿にして、本発明のコピー不可用紙にコピーすれば、コピー不可書類が製作できる。
【0015】
このコピー不可書類を原稿としたコピーは真っ黒にしか写らない。
【0016】
このコピー不可書類は、ブラックライトを照らすと、用紙全体に発色するが、印字は蛍光を抑えて発色しないので鮮明に判読できる。
【0017】
ブラックライトを照らさない状態において肉眼で見ると黒い用紙の上に黒い迷彩模様が有り、黒い印字の判読は困難である。
【0018】
【発明の効果】
こうすることにより、コピーによる情報の流出を防ぐことが出来る。
【0019】
また、ブラックライトがないと読めないので、盗み見され難い。
【0020】
合成紙や、フィルムなどベースの素材が違う用紙でも同じ効果が得られるので、素材は限定しない。
【0021】
印刷に替えて塗布しても同じ構造の用紙が製作できる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a paper structure and a method for producing a document.
[0002]
[Prior art]
In order to prevent important information from being copied by a copying machine and easily leaking, some of the copies may have warning characters when copied.
[0003]
In addition, there is an object in which a copy is made completely black by processing the surface like a mirror and applying irregular reflection of light.
[Problems to be solved by the invention]
Copying cannot be prevented if a warning character appears on the copy.
[0004]
Objects whose surface is processed like a mirror to apply a diffuse reflection of light so that the copy appears black are difficult to handle because they are curled by the heat of the printer.
[0005]
In addition, the characters are glaring and the characters are difficult to read.
[0006]
[Means for Solving the Problems]
A black camouflage pattern (2) is superimposed and printed on a paper (3) dyed or printed in black, and a structure having a fluorescent screen that emits black light from above is formed.
[0007]
The secret information and the like are printed out in black on this sheet.
[0008]
To the naked eye, there is a black camouflage pattern on black paper, and it is difficult to read the black print.
[0009]
When illuminated with black light, the entire fluorescent screen develops color, but the printed color is suppressed and the color is not developed, so it can be read clearly.
[0010]
The copy is only black.
BEST MODE FOR CARRYING OUT THE INVENTION
The paper is dyed or printed on the entire surface in black.
[0011]
Since there is a slight difference in color between the black color of the paper and the black color of the subsequent printing, camouflage such as random numbers and copy-forgery-inhibited patterns is superimposed and printed in black to make it more difficult to read.
[0012]
Then, the entire surface is printed with a colorless fluorescent ink that emits black light.
[0013]
The confidential information and the like are printed out in black on the non-copyable sheet of the present invention by a printer to produce a non-copyable document.
[0014]
Alternatively, if a document such as confidential information of a normal sheet is used as a manuscript and copied onto a non-copyable sheet of the present invention, a non-copyable document can be produced.
[0015]
A copy of this non-copyable document as a manuscript appears only black.
[0016]
This non-copyable document, when illuminated with black light, develops color on the entire paper, but the print is suppressed in fluorescence and does not develop color, so that it can be clearly read.
[0017]
When viewed with the naked eye in a state where the black light is not illuminated, there is a black camouflage pattern on black paper, and it is difficult to read the black print.
[0018]
【The invention's effect】
By doing so, it is possible to prevent information leakage due to copying.
[0019]
In addition, since it cannot be read without a black light, it is difficult to see it.
[0020]
The same effect can be obtained with synthetic paper or paper with a different base material such as film, so the material is not limited.
[0021]
Even if it is applied instead of printing, paper of the same structure can be manufactured.
