A random matrix moiré fringe anti-counterfeiting pattern and its manufacturing method

Abstract

The invention includes a random matrix moiré fringe anti-counterfeiting pattern and its production, identification method and application thereof. The random matrix moiré fringe anti-counterfeiting pattern of the present invention is four matrices of double-layer hidden characters or six matrices of three-layer hidden characters The random matrix moiré fringe anti-counterfeiting pattern of the present invention has higher information carrying capacity, and random factors make it more difficult to make, and ordinary counterfeiters cannot imitate it, so it has a better anti-counterfeiting effect; the random matrix moiré fringe of the present invention The concealment of anti-counterfeiting patterns is obviously better than that of ordinary parallel-line moiré stripes. The direction changes formed by the text hidden in parallel lines are not obvious. No matter whether you look at it with the naked eye or with a magnifying glass, you can only see disorderly dots. The hidden content cannot be seen; the random matrix moiré fringe anti-counterfeiting pattern of the present invention can be identified by using a grating sheet, and the identification method is regular and controllable, which will be more accurate and convenient for product anti-counterfeiting inspection.

Description

technical field [0001] The invention relates to the technical field of anti-counterfeiting, in particular to a random matrix moire fringe anti-counterfeiting pattern and a manufacturing method thereof. Background technique [0002] At present, there is a parallel-line Moire fringe anti-counterfeiting technology in the field of anti-counterfeiting printing. It is difficult to see the text hidden in the parallel lines when viewing with the naked eye, and the hidden text can only be seen when the special decryption detection grating is used for detection. This is a relatively effective anti-counterfeiting technology at present, but it still has the following shortcomings: the production method is simple and easy to be imitated. Its anti-counterfeiting software is specially made, but because the technical threshold is very low, most of the design software on the market can be imitated and made, and it is difficult to prevent the imitation of forgers; the concealment is poor, an...

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
