A processing method for anti-counterfeiting paper with gold and silver threads

Abstract

The invention relates to the technical field of anti-counterfeiting paper, in particular to a method for processing anti-counterfeiting paper with gold and silver threads in voids. It includes a surface paper layer and a base paper layer. The surface paper layer and the base paper layer are arranged side by side along the length direction and partially overlapped. The overlapping parts of the surface paper layer and the base paper layer are connected with each other to form an integrated structure; An anti-counterfeiting layer is interposed between the surface paper layer and the base paper layer, and the anti-counterfeiting layer, the surface paper layer, and the base paper layer are respectively connected with pulp to form an integrated structure; there are anti-counterfeiting patterns on the overlapping parts of the surface paper layers, and the anti-counterfeiting A part of the layer is exposed on the face paper layer through the anti-counterfeiting pattern. The present invention adopts gold and silver thread interlayer anti-counterfeiting technology, the gold and silver threads are arranged on the overlapped and bonded part, and the surface paper layer on the gold and silver thread anti-counterfeiting layer is subjected to missing engraving, so that the surface of the anti-counterfeiting paper displays various patterns combined with gold and silver threads ; Make the anti-counterfeiting graphics have particularity, uniqueness and distinguishing functions, simple processing, low cost, and good promotion and popularization prospects.

Description

technical field [0001] The invention relates to the technical field of anti-counterfeiting paper, in particular to a method for processing anti-counterfeiting paper with gold and silver threads in voids. Background technique [0002] With the development of the times and the advancement of technology, encryption or anti-counterfeiting paper is required in many occasions, such as common banknotes, invoices, lottery tickets, etc., all of which use a combination of special paper and various encryption technologies to achieve anti-counterfeiting and screening function. These encryption technologies include watermarking technology, laser identification marks, anti-counterfeiting codes, gold and silver thread interlayers and so on. However, the implementation methods of these encryption technologies are relatively complicated and costly, and most of them are suitable for the use of high-value materials, and their application range is relatively small. Therefore, the prior art st...
