Anti-counterfeit method by merging patterns to check

Abstract

The invention discloses an image combination checking anti-fake method, it produces the same pattern on the product and another carrier when using laser or printing technology to produce anti-fake pattern; or it cuts the anti-fake pattern into two parts at least, and part of the pattern is produced on the product, another part is produced on another carrier, thus the product and another carrier will have different part of the pattern, and the two parts will form a whole anti-fake pattern. The effect is excellent.

Description

Technical field: [0001] The invention relates to an anti-counterfeiting method for combined image checking, which belongs to the technical field of anti-counterfeiting. Background technique: [0002] At present, most of the anti-counterfeiting technologies in the prior art use laser technology or printing technology to make a complete anti-counterfeiting pattern on the product for anti-counterfeiting. Check the shortcomings, so its anti-counterfeiting effect is still not ideal. Invention content: [0003] The purpose of the present invention is to provide a kind of anti-counterfeiting method for checking and checking, which is not easy to imitate, can be checked, and is convenient to check, so as to overcome the deficiencies in the prior art. [0004] The present invention is realized like this: it comprises the method for making anti-counterfeiting patterns, characters or numbers on products by adopting laser technology or printing technology, when adopting laser technol...
