Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an anti-

The present invention relates to an anti-falsification printed matter which can not be visually identified on the original of a security product, but can be prevented from being counterfeited by a latent image developed during copying.

Recently, with the development of IT technology, as the resolution and reproducibility of computer related devices such as scanners, printers, multifunctional apparatuses and software have been improved, crimes of copying and using banknotes, checks, certificates and security documents are increasing.

In order to solve such problems, various forgery-proof prevention halftone dots have been developed. Conventionally, a method of preventing forgery and falsification by using ultraviolet ink, infrared ink, hologram, or the like has been attempted. However, But it is not difficult to recognize the contents of the original. In addition, it is inevitable to increase the production cost due to the addition of the hologram or the ink, or the raw material, the labor cost, and the additional process.

In order to make it difficult to grasp the contents of the original when copying banknotes, checks, certificates, security documents, etc., it is necessary to change the angles of lines and halftone dots, large halftone dots and small halftone dots, angle conversion of dotted lines and dotted lines, When copying into a curve, counterfeiting was prevented by developing the latent image. As such a patent document, there is Korean Patent Registration No. 0369111.

In this conventional technique, a method of forming a pattern using a halftone dot and a figure and making the screen density uniform is disclosed. In this case, the larger the size difference is, the better the separation effect between the lost portion and the emerging portion is achieved by disposing the size of the lost portion and the size of the emerging portion. However, if the size difference is large, The application is easy to see, and practicality is low.

In order to prevent such a problem, if the size difference between the background pattern and the emerging pattern is made small, the effect of the technique is remarkably lowered because the effect of disappearance and development of the radiation is insufficient. In addition, since the shape itself differs from the background pattern and the difference in the size of the emerging pattern, there is a disadvantage in that the applicability of the technology can be easily confirmed with the naked eye even in the original of the printed material before copying.

1. Korean Patent Registration No. 0369111 (published on Jan. 09, 2003)

It is not easy to visually identify the original configuration of various security products requiring security such as a banknote, a check, a passport, an identification card, a gift certificate, various certificates, security documents, and the like. The present invention is to provide an anti-falsification printed matter and a method of manufacturing the same, which can not easily identify the origin of the original copy even if the original is prominently displayed, and can easily identify the authenticity of the original by the latent image on the copy.

According to an aspect of the present invention, there is provided an anti-falsification printed matter comprising: a background unit having a plurality of background lines spaced apart from each other at a first predetermined interval; A unit latent image line divided into two fine lines and in which a gap line is inserted between neighboring fine lines includes a latent image portion spaced apart at a second predetermined interval, wherein the background portion and the latent image portion have the same unit area density .

In addition, the fine lines and the gap lines may extend in the same direction as the longitudinal direction of the background lines.

Also, the width of the background line: the first preset interval: the width of the gap line: the width of the fine line may be 0.26: 2: 1: 0.5.

The fine lines and the gap lines may extend in a direction perpendicular to the longitudinal direction of the background lines.

In addition, in the unit area, the number of background lines and the number of unit latent image lines may be 2.5: 1.

The width of the gap line may be 20 占 퐉 to 70 占 퐉.

In addition, the width and the number of the fine lines can be determined according to the width of the gap line.

In addition, the fine lines may be formed by dotted lines or solid lines.

In addition, the fine line and the background line may be one of a straight line, a curved line, an oblique line, and a geometric pattern.

Also, the density of the unit area may be 5% to 15%.

A method of manufacturing an anti-falsification printed matter according to an embodiment of the present invention includes a background portion in which a plurality of background lines are spaced apart from each other at a first predetermined interval, and a background portion in which at least two fine lines And a unit latent image line in which a gap line is inserted between neighboring fine lines forms a latent image portion spaced apart at a second predetermined interval and the density of the unit area in the background portion and the latent image portion can be made the same .

As described above, according to the present invention, in the anti-falsification printed matter of the present invention, since the latent image portion is formed as a unit line composed of the gap lines formed between the fine lines and the fine lines, it is not easy to visually identify the latent image on the original do.

In addition, since the latent image applied to the original at the time of copying the security product is prominently displayed, it is difficult to grasp the configuration of the original even in the copy.

In addition, the gap line of the original is filled with ink at the time of original copying, and the latent image is prominently displayed, thereby making it easier to identify the authenticity of the original.
