Paper surface special code anti-counterfeit label and preparation method thereof

Abstract

The invention belongs to the technical field of anti-counterfeiting products, and particularly relates to a paper surface special code anti-counterfeiting label and a preparation method thereof. The label is composed of a printing layer, a coated paper layer, an adhesive layer and a silicone oil paper layer which are sequentially arranged from top to bottom. The anti-counterfeiting information printed by the printing layer is composed of a printed image-text and a special anti-counterfeiting code converted into a picture form. The invention discloses a paper surface special code anti-counterfeit label. According to the method, original data is converted into a picture form, and then typesetting design is carried out on the converted picture and an identification printed image, so that theprinting quality of an invisible code picture can be guaranteed, the requirement of high-speed printing can be met, variable information tagging can be carried out one by one, and the problem of high-speed tagging of a large number of commodity identifications is solved; 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 easy to copy.

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 special code on paper 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 na...
