Printing method and device for anti-counterfeiting two-dimensional code with printing height

Abstract

The invention provides a printing method and device for an anti-counterfeiting two-dimensional code with a printing height. The printing method comprises the following steps: selecting the printing height from the preset height range; generating a three-dimensional anti-counterfeiting image according to the printing height and the anti-counterfeiting information of a product; and printing on the corresponding printing substrate of the product according to the three-dimensional anti-counterfeiting image and the preset printing height in a three-dimensional printing manner, so as to obtain the anti-counterfeiting two-dimensional code with the printing height. Since the printing height is added when the anti-counterfeiting two-dimensional code is printed, so that the finally printed anti-counterfeiting code is a three-dimensional anti-counterfeiting code. Since the measuring difficulty of the printing height of the generated three-dimensional anti-counterfeiting code is very high, the reproducibility of the three-dimensional anti-counterfeiting code is reduced, the anti-counterfeiting code of which the height is the same as those of the anti-counterfeiting codes of products manufactured by quality product manufacturers is difficultly printed by malicious sellers, the accuracy of distinguishing product authenticity through the height information of the anti-counterfeiting code is improved, the malicious sellers counterfeiting the quality products are distinguished through the printing height by the quality goods manufacturers, and the accountability of the malicious sellers is tracked by the quality goods manufacturers.

Description

technical field [0001] The invention relates to the technical field of anti-counterfeiting two-dimensional codes, in particular to a method and device for printing anti-counterfeiting two-dimensional codes with high printing height. Background technique [0002] The manufacturer usually prints an anti-counterfeiting two-dimensional code on the outer packaging of the product. The anti-counterfeiting two-dimensional code includes the anti-counterfeiting information of the product, and the anti-counterfeiting information is used to confirm whether the product is a counterfeit product. [0003] At present, there are a large number of counterfeit products in the market, and the sales of counterfeit products have brought huge economic losses and reputation losses to genuine manufacturers. Malicious merchants will be held accountable. At present, manufacturers of authentic products usually scan the anti-counterfeiting two-dimensional code printed on the product sold in the market,...

[0004] However, since malicious merchants can scan the anti-counterfeit QR codes of genuine products to obtain the anti-counterfeit information included in the anti-counterfeit QR codes, they can generate the same anti-counterfeit QR codes as those of genuine manufacturers according to the anti-counterfeit information, that is, the current anti-counterfeit QR codes can be High reproducibility, resulting in low accuracy of identifying product authenticity through anti-counterfeit QR codes
