Problems solved by technology

The fiber ink printing unit is suitable for ink printing containing large-sized fibers, but during the printing process, when the ink containing large-sized fibers is attached to the gravure roll for printing, the size of the fibers is significantly smaller than that of the gravure roll. The fibers in the ink will be deposited in the pits, making it difficult for the ink to be printed on the printing material with the fibers, making it difficult to form an easily identifiable anti-counterfeiting mark on the printing material

Abstract

The invention provides a transfer printing device for random texture anti-counterfeit printing, and relates to the field of anti-counterfeit printing. Viscous liquid doped with fibers is contained in a liquid collection tank of the transfer printing device. A flexible printing roller is partially immersed in the viscous liquid of the liquid collection tank. The flexible printing roller rotates to transfer the viscous liquid adhering to the flexible printing roller to a transfer roller. Due to the fact that the transfer roller is provided with a concave pit with the caliber obviously smaller than the length of the fibers, the viscous liquid doped with the fibers can be transferred to the transfer roller easily, and the phenomenon of fiber aggregation cannot happen. The transfer roller rotates to transfer the viscous liquid of the transfer roller to a printing roller, the printing roller rotates to print the viscous liquid of the printing roller to a printed material, and a random texture anti-counterfeit layer is formed. The transfer printing device can guarantee that the viscous liquid containing the fibers is smoothly printed to a specific area of the printed material, the printing effect is good, and efficiency is high. The invention further provides a transfer printing system for random texture anti-counterfeit printing. The transfer printing system comprises the transfer printing device. Anti-counterfeit marks easy to recognize can be obtained in a printed manner, and a user can conveniently inquire anti-counterfeit feature information of products according to the anti-counterfeit marks.

Description

technical field [0001] The invention relates to the field of anti-counterfeiting printing, in particular to a pad printing device and pad printing system for random texture anti-counterfeiting printing. Background technique [0002] Anti-counterfeiting printing is a comprehensive anti-counterfeiting technology, which is a branch of special printing. Anti-counterfeiting printing refers to the use of printing methods to prevent imitation, duplication or forgery without the permission of ownership. Among them, the structural texture anti-counterfeiting printing method is to select a clear material (carrier) with a random structural texture (such as the texture formed by the added fibers in the paper) to make an anti-counterfeiting marker; and print a unique identification number; The random structure texture characteristic information on the computer is scanned and collected, as the anti-counterfeiting identification characteristic information (i.e. the basis for identifying au...
