Unique texture anti-counterfeiting two-dimensional code printing equipment for packaging material

Abstract

The invention discloses unique texture anti-counterfeiting two-dimensional code printing equipment for a packaging material. The equipment comprises a server, an unwinding device, a conveying mechanism,a transverse cutting device, a stacking device, a texture jet printing device, a photocuring device, a texture scanning device, a two-dimensional code printing device, a drying device and an image collecting device. The conveying mechanism, the transverse cutting device, the stacking device, the texture jet printing device, the photocuring device, the texture scanning device, the two-dimensionalcode printing device, the drying device and the image collecting device are sequentially arranged in the conveying direction of the conveying mechanism. UV gloss oil is stored in the texture jet printing device, and at least one of carbon particles, glitter powder, carbon fibers, nylon fibers and cotton fibers is contained in the UV gloss oil. The packaging material is sequentially subjected to anti-counterfeiting texture jet printing, curing and drying, texture image acquisition, anti-counterfeiting two-dimensional code printing, drying and two-dimensional code image acquisition. Texture feature extraction and anti-counterfeiting two-dimensional code information generation are carried out on the server, the overall structure is simple and compact, three-dimensional, natural and unique natural textures are formed on the packaging material after jet printing and cannot be copied, and therefore the purposes of unique identification and unique anti-counterfeiting are achieved.

Description

technical field [0001] The invention relates to a printing device, in particular to a unique texture anti-counterfeiting two-dimensional code printing device for packaging materials. Background technique [0002] At present, counterfeit commodities such as cigarettes, alcohol, medicines, food, etc. of various commodities and bills, as well as forgery of certificates, tickets, tickets, documents, tax invoices and bank bills are emerging in the society and are not uncommon, which not only damages the legality of consumers. It may even endanger the health and life of consumers; it also disrupts the market order, damages the commercial reputation and interests of manufacturers, and seriously endangers the country's financial security and financial order. [0003] Two-dimensional code technology has the characteristics of large storage capacity, high confidentiality, high traceability, strong damage resistance, large redundancy, and low cost. These characteristics are especially ...

Problems solved by technology

For the same product, the outer packaging design of each specific product is the same, but the texture difference caused by the slight difference in the manufacturing process of the outer packaging and the pattern printed on the outer packaging during printing cannot be completely consistent. As well as the differences in the internal structure and texture of the outer packaging itself (usually paper or plastic materials) that cannot be completely the same, these factors all lead to changes in color and color in a certain area on the outer packaging of the product, and variations in patterns. Variations, surface textures, and differences in the texture of the internal structure are unavoidable

[0008] However, as stated in the above-mentioned Chinese invention patent application, in the texture feature extraction area, there may be extremely slight differences in texture, color, pattern, etc., which are difficult to distinguish in image processing. For texture feature extraction, the feature parameters that may be extracted Basically the same, which cannot guarantee the uniqueness of the QR code. In order to ensure that the feature parameters in the texture feature extraction area of ​​each product are significantly different, this Chinese invention patent application artificially adds some randomly generated parameters in the feature extraction area. Textures, these textures can be stripes, patterns, dot matrix, characters, numbers, etc. or randomly generated lines, these textures can be randomly generated and printed on the texture feature extraction area after the texture feature extraction area is determined, or can be randomly generated in advance Texture and calculate its texture feature parameters, and print the texture on the texture feature extraction area while printing the QR code

[0009] However, the above-mentioned textures and patterns based on the product itself have basically the same defects, while the artificially added "stripes, patterns, dot matrix, characters, numbers, etc. or randomly generated lines" rely on computer programs, which seem random, but As long as its algorithm is cracked, it can still be copied, and it is difficult to achieve the purpose of unique anti-counterfeiting identification of products
