Special anti-counterfeiting code hot stamping foil and preparation method thereof

Abstract

The invention belongs to the technical field of anti-counterfeiting products, and particularly relates to a special anti-counterfeiting code hot stamping foil and a preparation method thereof. The anti-counterfeiting code hot stamping foil is composed of a gum layer, an aluminum layer, a printing layer, a holographic information layer, an imaging layer, a release layer and a PET layer which are sequentially arranged from top to bottom, and anti-counterfeiting information printed by the printing layer is composed of printed images and texts and special anti-counterfeiting codes converted into picture forms. Based on the special code anti-counterfeiting hot stamping foil, 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 the printing 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 a special anti-counterfeiting code hot stamping foil 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 e...

Problems solved by technology

[0005] At present, there are two main types of hot stamping foils, one is ordinary hot stamping foil, this kind of hot stamping foil only has the function of Anti-counterfeiting and holographic anti-counterfeiting are integrated, which greatly improves the anti-counterfeiting strength of the hot stamping foil. The fly in the ointment is that the sticking performance of the back glue of the hot stamping foil is small, and the quality problem of scratching the QR code is prone to occur, resulting in the unreadable QR code.

[0006] In CN 206551590 "A Two-Dimensional Code Hot Stamping Film with a Transparent Holographic Anti-counterfeiting Layer", the two-dimensional code of the hot stamping foil is formed by an aluminum washing process, which is a well-known technology in the industry, and because hot stamping The peeling effect of the foil is not good, which will lead to the peeling of the aluminum layer is not clean, which will make the QR code unreadable
