Abstract
Description
The present invention relates to a method of manufacturing a printed material for preventing and counterfeiting copying, and more particularly, a latent image can be distinguished from a copy such as money, securities, identification cards, and various documents requiring security. It's about technology.
With the development of technology, excellent digital copiers, scanners, etc. (hereinafter referred to as 'copy devices') having high resolutions have emerged.
Such a copying device is capable of precise copying of printed matter, providing convenience to life, but when abused, there is a problem in that a counterfeit money, a counterfeit document, or the like can be manufactured.
To solve this problem, anti-counterfeiting techniques using various special inks have been provided. However, these special inks became available over time and could not be a fundamental solution.
Another solution to the problem was to provide a technique that included a latent image on the original and that the latent image appeared when copying.
However, such a technique causes a problem that when a density flows during the copying of the copying device, the latent image is not copied and thus counterfeiting or copying prevention can not be effectively performed.
The present invention has been made to solve the above-mentioned problems according to the prior art, and an object of the present invention is to provide a technique in which a latent image may appear even when copying by blurring a density when copying using a copying apparatus.
In order to achieve the above object, the manufacturing method of the anti-counterfeiting and copy interference printing according to the embodiment of the present invention, in the production method of the anti-counterfeiting and copy interference printing, includes a latent image portion and a background portion represented on the printed matter The latent image portion may include a print cell having a first color density and a blank cell having a second color density between the print cells having a predetermined graphic shape and disposed at equal intervals, and the background portion may be formed in the latent image portion. The third color concentration corresponding to the value obtained by multiplying the area occupied by the print cell by the first color concentration and the area occupied by the blank cell by the second color concentration divided by the area of the latent image is printed by color. It features.
In the present invention, the print cell of the latent image portion may have a size of 0.1 to 0.7mm in width and length.
In the present invention, the print cell of the latent image portion may have a screen concentration of 10 to 40% at 100 to 175 lines of the screen tone player.
According to the present invention, it is possible to provide a method of manufacturing a printed product in which a latent image looks blurry on the original, and the latent image appears even when the density is blurred.
In addition, a latent image is apparently displayed at the time of copying, thereby reducing the readability of the printed matter through the copy, thereby providing a technology for preventing the leakage of information.
In the following, embodiments of the present invention are described with reference to the accompanying drawings.
In the following description of the present invention, if it is determined that detailed descriptions of related known functions or configurations may unnecessarily obscure the subject matter of the present invention, the detailed description will be omitted. In addition, the terms to be described later are terms set in consideration of functions in the present invention, and these terms may vary according to the intention or custom of the producer producing the product, and the definition of the terms should be made based on the contents throughout the present specification.
First embodiment
First, with reference to the accompanying drawings Figures 1 and 2 will be described a method of producing a printed article for preventing and counterfeit radiation according to a first embodiment of the present invention.

Hereinafter, a second embodiment of the present invention will be described with reference to FIG. 3.
Figure 3 shows the main part of the printed matter produced according to the second embodiment of the present invention.
As shown in FIG. 3, the printed matter according to the second embodiment of the present invention is substantially except that the area ratio of the
As can be seen from the second embodiment, the present invention can freely adjust the area ratio of the print cell and the margin cell. On the other hand, although not described, it is obvious that various shapes may be used in the shape of the print cell.
The embodiments of the present invention have been described above with reference to the accompanying drawings.
However, it is to be noted that the present invention is not particularly limited only to the above-described embodiments, and that various modifications and changes can be made by those skilled in the art within the spirit and spirit of the appended claims as necessary.
Figure 1 shows a printed matter produced according to the first embodiment of the present invention.
FIG. 2 is an enlarged view of portion A of FIG. 1. FIG.
Figure 3 shows the main part of the printed matter produced according to the second embodiment of the present invention.
