Equipment splicing printing method and printing device and production device of graphic and text anti-counterfeiting paper

Abstract

The invention provides equipment splicing printing method and printing device and a production device of graphic and text anti-counterfeiting paper. The equipment splicing printing device includes atleast two sets of printing equipment, the printing equipment is mounted above the net part of a paper making machine, and each printing equipment includes a printing part and a first driving mechanismfor driving the printing part to move; and the printing path of each printing part is parallel to the moving path of the net part of the paper making machine, the printing path of the printing part of each set of printing equipment is distributed in a staggered mode in the direction of being perpendicular to the moving path of the net part of the paper making machine, and the first driving mechanisms are in synchronized transmission with the driving mechanism of the net part of the paper making machine. The equipment splicing printing method and printing device and the production device of the graphic and text anti-counterfeiting paper do not need to transform the complex structure of existing printing equipment, full print graphic and text anti-counterfeiting pattern can be printed on the paper face manufactured by a wide-width paper making machine, and the production efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of papermaking, and in particular relates to an equipment splicing printing method, a printing device and a production device for graphic and text anti-counterfeiting paper. Background technique [0002] Anti-counterfeiting paper refers to the special paper with marks on the surface or hidden patterns, patterns, watermarks and other graphics on the inner layer, which is not easy to imitate, counterfeit or change. It is to prevent imitation or duplication of specific paper materials without the permission of the owner. , bills, etc. At present, most of the production of various bills use anti-counterfeiting paper, such as various industrial and commercial sales invoices, administrative and public institution charging invoices, invoices for catering, taxis, etc. In the prior art, the anti-counterfeit paper usually includes a bottom layer, a core layer and a surface layer, and a graphic anti-counterfeit patter...

AI Technical Summary

Problems solved by technology

[0003] When producing anti-counterfeiting paper, generally the wet paper pages are produced through the wire section of the paper machine, and then the graphic anti-counterfeiting patterns are printed on the wet paper pages. The width of the wet paper produced by the wire section is also extremely wide compared with the width of the printing equipment, even several times the width of the printing equipment, and with the development level of the existing technology, it is impossible to produce and manufacture paper machines with the same size as the paper machine wire. Printing equipment with similar format, which caused the one-time printing process to be unable to complete the full-format printing of wet paper pages on the paper machine when printing graphic anti-counterfeiting patterns, which greatly reduced production efficiency and resulted in a large number of copying
