Anti-counterfeit mark printed on surface of crystal

Abstract

The invention discloses an anti-counterfeit mark printed on the surface of a crystal, capable of being recognized by an instrument and having an anti-counterfeit function. Essentially, a graphic element with information stored inside is printed on the surface of a printing medium through a special printing method or pigment or ink, the printing medium is the crystal, and a solidified mark resistant to copying and cracking is finally obtained. One characteristic of the anti-counterfeit mark is that a recognition instrument can be used to recognize the anti-counterfeit mark and extract anti-counterfeit information stored in the anti-counterfeit mark, so that the objective of direct true-false judgment on a crystalline article through the anti-counterfeit mark is achieved. By the anti-counterfeit mark, the problem of difficulty in printing a high-accuracy anti-counterfeit pattern on the crystal is solved; the anti-counterfeit mark has good effect on solving the problem of implanting of the anti-counterfeit mark at a small area.

Description

【Technical field】 [0001] The invention discloses an anti-counterfeit mark, in particular provides an anti-counterfeit mark printed on the surface of a crystal. [0002] 【Background technique】 [0003] Crystal materials are generally used in various decorations because of their good light transmittance, stable properties, and pure texture. Natural crystal materials are generally preferred, but with the current level of technology, various crystals can also be artificially generated. But in terms of value, artificial crystals are far lower than natural materials. In social and economic life, it is very common to use inferior goods as good ones and artificial ones as natural ones. Many counterfeiters use low-value artificial materials as natural materials to deceive consumers and obtain high profits. Therefore, it is particularly important for the anti-counterfeiting of crystals. However, due to the small flat surface of the crystal and the difficulty of implanting ant...

Problems solved by technology

[0009] The above are the general production methods and anti-counterfeiting methods for anti-counterfeiting identification certificates, but the above printing technologies do not actually have a high technical threshold, and related printing equipment and anti-counterfeiting materials can also be obtained through normal channels.

The most important thing is that the anti-counterfeiting certificate is separated from the item to be anti-counterfeiting. The anti-counterfeiting identification certificate cannot directly identify the authenticity of the item. Counterfeiters can completely forge the certificate and the crystal item in an alternative way.

Therefore, this method is not the most effective anti-counterfeiting method
