'Color watermark' anti-falsification paper and preparation method thereof

Abstract

The invention relates to a 'color watermark' anti-falsification paper and a preparation method thereof. The 'color watermark' anti-falsification paper at least comprises two fiber layers, wherein the first layer is a basic layer formed by white paper pulp, the second layer is a color watermark layer formed by color paper pulp; the color watermark layer and the white basic layer are combined on the net part of a cylinder mould machine to form the 'color watermark' anti-falsification paper with one white surface and the other surface formed by a white base and the color paper pulp. The preparation method of the 'color watermark' anti-falsification paper comprises the following steps: a part of a common black watermark net without watermark patterns cannot carry out water filtration caused by being coated by resin so as not to be coated with paper pulp, and therefore a color watermark net is formed; the color paper pulp forms a 'color watermark' with special patterns after being coated, and the 'color watermark' is difficult to imitate and counterfeit due to limitation of the color, and therefore the anti-falsification capability and the anti-falsification effect are enhanced. According to the preparation method disclosed by the invention, the traditional cylinder part is transformed and the wet paper moisture of a second cylinder mould is reduced. The produced 'color watermark' anti-falsification paper accords with the national standard.

Description

technical field [0001] The invention relates to anti-counterfeit paper and its preparation method, in particular to a "color watermark" watermark anti-counterfeit paper and its preparation method. 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 orde...
