The invention relates to an anti-counterfeiting printed matter and a manufacturing method thereof. The present invention aims to provide an anti-counterfeiting printed matter printed with a printed pattern that not only makes it difficult to recognize a latent image portion of a security pattern with the naked eye, but also cannot recognize the latent image portion even by copying or scanning. In addition, the present invention aims to provide an anti-counterfeiting printed matter that can determine whether it is a counterfeit product by using an application program (application) of a smart device that can recognize the anti-counterfeiting on the original printed matter instead of copying or scanning. The printed pattern is printed, and the latent image part of the security pattern is derived from the recognized printed pattern, and the shape of the derived latent image part can be displayed on the screen. The present invention aims to provide an anti-counterfeiting printed matter using only CMYK ink. The invention only uses CMYK ink for printing, shortens the process, shortens the manufacturing time of printed matter, and reduces the manufacturing cost of printed matter. In addition, in the present invention, the two or three colors whose distribution sum in the color-separated CMYK is above the preset value are printed at a ratio of 2:1.6 to 1.8, and the rest of the colors are printed at a ratio of 1:1. This can improve the concealment of the latent image, prevent the latent image from appearing at the time of copying or scanning, and determine whether it is a forgery or not with an application (app) only by the smart device. In addition, in the present invention, the size of characters or images of the latent image portion is printed according to a preset value, thereby improving the latent image hiding power to the naked eye.
Description
technical field [0001] The present invention relates to a printed matter, and more specifically, to an anti-counterfeit printed matter and a manufacturing method thereof. Background technique [0002] In recent years, with the development of IT technology, the resolution and reproducibility of computer-related equipment such as scanners, printers, multi-function devices and software have been continuously improved, resulting in easy copying and use of bank notes, checks, various certificates and security documents Other crimes are also on the rise. [0003] In order to solve the above-mentioned problems, many techniques for preventing copy forgery have been studied, as shown in Korean Laid-Open Patent No. 10-2001-0111242, most of them are printing techniques for preventing copy forgery, that is, when copying with a color or black and white copier or using a scanner When scanning printed matter such as currency, securities, ID cards, credit cards, and various certificates fo...
