Paper surface uncovering type special code anti-counterfeiting label and preparation method thereof

Abstract

The invention belongs to the technical field of anti-counterfeiting products, and particularly relates to a paper surface uncovering type special code anti-counterfeiting label and a preparation method thereof. The label is composed of a second printing layer, a coated paper layer, a PE layer, an isolation layer, a first printing layer, a white ink layer, an adhesive layer and a silicone oil paperlayer which are sequentially arranged from top to bottom. The anti-counterfeiting information printed by the first printing layer is composed of a printed image-text and a special anti-counterfeitingcode converted into a picture form. The special code anti-counterfeiting label can be uncovered and is divided into a stripping part and a retaining part, and the stripping part sequentially comprises a second printing layer, a coated paper layer and a PE layer from top to bottom. The reserved bottom part sequentially comprises an isolation layer, a first printing layer, a white ink layer and anadhesive layer from top to bottom. According to the paper surface uncovering type special code anti-counterfeiting label, when the anti-counterfeiting code is damaged by 75%, the anti-counterfeiting code can still be read, the error correction rate is high, and the anti-counterfeiting code is not prone to being copied.

Description

technical field [0001] The invention belongs to the technical field of anti-counterfeiting products, and in particular relates to an anti-counterfeiting label with a paper-surface-revealing special code 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 vi...

Problems solved by technology

[0005] The problem with the existing peel-off anti-counterfeiting labels is that due to the many objective factors in the peel-off type, there will be a phenomenon of peeling off the two-dimensional code, and because the error correction rate of most two-dimensional codes is 15%, as long as the two-dimensional code is destroyed An anchor point of the code can easily lead to unreadable QR codes and bring unnecessary losses to consumers
