Problems solved by technology

[0003] In the existing technology, the selection of anti-counterfeiting information is limited to simple shapes and single letters. With the increase of anti-counterfeiting information and the increase in complexity, the concealment of anti-counterfeiting information decreases, and it is easy to be directly perceived by human eyes. The performance is not ideal

Abstract

The invention discloses a Morie fringe anti-counterfeiting method for improving anti-counterfeiting information concealment. The method comprises the following steps: (1) preparing an original drawingand anti-counterfeiting information; (2) performing half-tone processing; (3) encrypting the anti-counterfeiting information; and (4) synthesizing an image. Through the method disclosed by the invention, the selection range of each of the original drawing and the anti-counterfeiting information is greater, the encryption and decoding are realized in the image, and the concealment and the extraction recognition performance are strong.

Description

technical field [0001] The invention belongs to the technical field of grating anti-counterfeiting, and in particular relates to a moiré anti-counterfeiting method for improving the concealment of anti-counterfeiting information. Background technique [0002] At present, most of the main printing anti-counterfeiting technologies are based on high-precision equipment and special materials. The cost of printing anti-counterfeiting is relatively high, and once the materials and equipment used for printing anti-counterfeiting are obtained, they will be copied in large numbers, thus losing anti-counterfeiting effect. Images and texts that need to be printed and reproduced are usually output through halftone screening. The anti-counterfeiting technology based on moiré is a kind of anti-counterfeiting technology based on the current printing anti-counterfeiting technology and the production conditions of ordinary printing enterprises. Small laziness, simple anti-counterfeiting pro...
