Manufacturing method of color watermark anti-counterfeiting paper

Abstract

The invention discloses a manufacturing method of color watermark anti-counterfeiting paper. The method comprises the following steps: 1, hollowing out a to-be-printed pattern by a second hollow-out layer needle, immersing a second hollow-out layer in a solution composed of an isolation resin, drying, and compounding a first base layer and the second hollow-out layer at the net part of a cylinderpapermaking machine to form first color printing paper, wherein the back surface of the first color printing paper is of a base white structure, and the front surface of the first color printing paperis of a white structure with the inner portion being base white and the outer portion being covered with the isolation resin; 2, coating the front surface of the first color printing paper with dyedcolor paper pulp, so that the hollow-out pattern of the second hollow-out layer is filled with the color paper pulp to form color watermark patterns, wherein the thickness of a third color watermark layer is flush with the thickness of the second hollow-out layer, and at the moment, the first color printing paper becomes second color printing paper with the color patterns; and 3, after the secondcolor printing paper is dried, correspondingly compounding the color surface of the second color printing paper and a fourth base layer at the net part of the cylinder papermaking machine to form a finished product.

Description

technical field [0001] The invention relates to the field of color printing, in particular to a method for manufacturing color watermark anti-counterfeiting paper. Background technique [0002] Watermark anti-counterfeit paper is the most widely used anti-counterfeit paper at present, and banknote paper is a typical representative of watermark anti-counterfeit paper. Most of the traditional watermark anti-counterfeiting paper is white paper, and a small amount is colored paper. Regardless of white paper or colored paper, its technical feature is: the watermark part and the paper part are composed of pulp of the same color. Although this kind of paper has anti-counterfeiting function, but in the information age with rapid development of science and technology, due to the insufficient anti-counterfeiting strength of this kind of anti-counterfeiting paper, counterfeiting of RMB and invoices occurs from time to time, disrupting the economic order and people's life.
