what you need should be the anti-counterfeiting technology generated synchronously with the printing technology, that is to say, the anti-counterfeiting technology should be printed! However, the anti-counterfeiting technology of printing can be used for any commodity that needs to be printed to inform consumers of what it is and what brand it is. If the printed anti-counterfeiting code itself needs to be taken by others, it can not be copied. Now only S2i anti-counterfeiting technology can be controlled in the market. In addition to being copied, the code can also store a large amount of information. The theoretical value is 100 times that of ordinary two-dimensional code. Because the printing accuracy is required to be high, it can only be realized with more than 2400dpi, and the printing needs CPT plate making!
