Texture anti-counterfeiting mark containing pattern layer

Abstract

The invention belongs to the technical field of texture anti-counterfeiting and relates to an anti-counterfeiting mark with a pattern layer. The mark comprises randomly distributed texture elements. The pattern layer contains codes, the pattern layer is a photosensitive or photoetching pattern layer, and the distribution characteristics of the codes on an anti-counterfeiting mark to be identifiedand randomly distributed texture elements are obtained through one-time shooting under an amplification condition, so that the authenticity identification of the anti-counterfeiting mark can be realized, and the authenticity identification of an anti-counterfeiting object to which the anti-counterfeiting mark is attached is further completed. The photosensitive pattern is silver salt photosensitive; the lines can be as thin as 1 micron; therefore, the two-dimensional code in the pattern layer can be made very small; the area of the whole anti-counterfeiting mark can be made very small; the area of the anti-counterfeiting mark can be smaller than 1 mm < 2 >, the market application prospect is wide, the problem that some special products such as jewelries, watches and spectacle frames on themarket need small and thin anti-counterfeiting marks can be thoroughly solved, and the invention further provides an anti-counterfeiting pull line comprising the anti-counterfeiting mark containing the pattern layer.

Description

technical field [0001] The invention belongs to the technical field of texture anti-counterfeiting, in particular to a small and thin anti-counterfeiting mark containing a pattern layer. Background technique [0002] Texture imitation refers to storing the texture distribution pattern or random characteristics of the distribution pattern on the anti-counterfeiting label in the database in advance, and calling the random texture distribution pattern or the random characteristics of the distribution pattern in the database for comparison during identification to determine the authenticity of the product. [0003] Random texture anti-counterfeiting technology is a very promising anti-counterfeiting technology, it can finally solve the problem of public anti-counterfeiting, because the formation of random texture distribution involves an uncontrollable random process, the process is that the producers themselves cannot The same distribution pattern is formed for the second time ...

AI Technical Summary

Problems solved by technology

[0004] Texture anti-counterfeiting technology has begun to be applied to the anti-counterfeiting of various products, but at present, many applications of texture anti-counterfeiting labels require small and thin anti-counterfeiting labels, such as jewelry, exquisite items, watches, glasses frames, etc., requiring anti-counterfeiting labels as small as 1mm 2 In the following, it is easy to identify and complete the identification in one shot. The existing technology has not yet provided a solution for such a demand, and it needs to be solved urgently.
