Random matrix moire fringe anti-fake pattern and manufacturing method thereof

Abstract

The invention provides a random matrix moire fringe anti-fake pattern and a manufacturing and identifying method and application of the random matrix moire fringe anti-fake pattern. The random matrix moire fringe anti-fake pattern comprises four matrixes of two layers of hidden texts or six matrixes of three layers of hidden texts. The random matrix moire fringe anti-fake pattern has high information bearing capacity, random factors are added, the manufacturing difficulty is high, a common forger cannot copy the pattern, and therefore the random matrix moire fringe anti-fake patter has the good anti-fake function. The invisibility of the random matrix moire fringe anti-fake patter is remarkably higher than that of a common parallel line type moire fringe, the change of the direction formed by the text content hidden in parallel lines is not obvious, and no matter whether people see the random matrix moire fringe anti-fake with the naked eyes or a magnifying lens, people can only see chaotic dotted lines and cannot see the hidden content. The random matrix moire fringe anti-fake can be identified with a grating piece, the identification method is regular and controllable, and product anti-fake inspection can be more accurate and convenient.

Description

technical field [0001] The invention relates to the field of anti-counterfeiting technology, in particular to a random matrix moiré fringe anti-counterfeiting pattern and a manufacturing method thereof. Background technique [0002] At present, in the field of anti-counterfeiting printing, there is a parallel-line Moiré fringe anti-counterfeiting technology. Its production method is to design one or several groups of parallel lines with different directions in a certain area of ​​a bill and other printed matter, and use words on several groups of parallel lines to form tiny stripes. It is difficult to see the text hidden in the parallel lines when viewed by the naked eye, and the hidden text can only be seen when the special decryption detection grating film is used for detection. This is a relatively effective anti-counterfeiting technology at present, but it still has the following disadvantages: the production method is simple, and it is easy to be imitated.

AI Technical Summary

Problems solved by technology

This is a relatively effective anti-counterfeiting technology at present, but it still has the following disadvantages: the production method is simple, and it is easy to be imitated. Anti-counterfeiting software is specially made, but because the technical threshold is very low, most of the design software currently on the market can be imitated, and it is difficult to prevent counterfeiters from imitating; the concealment is poor, and it is easy to be distinguished by naked eyes. The content, the direction change formed by the text content hidden in the parallel lines is usually more obvious, and the content can be roughly distinguished when the grating film is not used for detection, and the hidden content can be seen after some technical processing; the detection effect is poor , in order to increase the concealment of parallel-line moiré fringes, when using parallel-line moiré fringes to design anti-counterfeiting patterns, most of them will minimize the direction change of parallel lines, but this makes it difficult to see clearly when using grating film detection hidden content
