Problems solved by technology

The anti-counterfeiting code used in this special anti-counterfeiting code tag is an invisible code that does not reduce the aesthetics of product packaging. It can realize fast and accurate identification, solve the problem of high-speed code assignment for a large number of product labels, and has a high error correction rate. When damage occurs, it can also be accurately read, which solves the problem that the two-dimensional code is easy to be copied; the invention also provides its preparation method

Abstract

The invention belongs to the technical field of anti-counterfeiting products, and particularly relates to a special anti-counterfeiting code tag and a preparation method thereof. The tag is composed of a covering layer, a protection layer, a first printing layer, a substrate layer and a second printing layer arranged in sequence from the top down, wherein special anti-counterfeiting codes printedon the second printing layer are corresponding to verification codes printed on the first printing layer one by one. According to the special anti-counterfeiting code tag provided by the invention, the special anti-counterfeiting codes in the second printing layer are hidden codes that does not affect the appearance of commodity packaging, can be quickly and accurately recognized, can be formed into vector data, and can be applied to batch printing of high speed variable information; and when 75% anti-counterfeiting codes are damaged, and the anti-counterfeiting codes are incomplete, the anti-counterfeiting codes still can be read, and thus is high in error correction ate, and the anti-counterfeiting codes are not prone to copy.

Description

technical field [0001] The invention belongs to the technical field of anti-counterfeiting products, and in particular relates to a special anti-counterfeiting code hanging tag and a preparation method thereof. Background technique [0002] At present, two-dimensional code has been widely used in all walks of life and people's daily life. It can be quickly read by a reader with a camera. Compared with the previous barcode, two-dimensional code can store more abundant information, but two-dimensional Code still faces its own problems and challenges from the outside world. [0003] Since the two-dimensional code is square and printed directly on the flat substrate in black and white, this has a huge impact on the aesthetics of some products, and the two-dimensional code visible to the naked eye is easy to be copied, and the security is not high. Existing two-dimensional codes are printed on commodities or other carriers in black and white, and are visible to the naked eye. On...
