Embodiment 1

[0021] This embodiment is a "color watermark" anti-counterfeiting paper, which is composed of two layers of fibers. The first layer of "color watermark" watermark anti-counterfeiting paper composed of two layers of fibers is a white base layer made of white pulp, and the second layer is a color watermark part made of colored pulp. The wire part of the paper machine is compounded to form one side is white and the other side is white

[0022] "Color watermark" watermark anti-counterfeiting paper composed of substrate and colored pulp.

[0023] The "color watermark" watermark anti-counterfeiting paper composed of three layers of fibers, the first layer is the base layer composed of white pulp, the second layer is the color watermark layer composed of colored pulp, the third layer is the base layer composed of white pulp, and the second layer is the base layer composed of white pulp. The first layer and the third base layer sandwich the color watermark part made of colored pul...

Embodiment 2

[0029] A method for preparing "color watermark" watermark anti-counterfeiting paper, the method uses a double-drum paper machine or a triple-drum paper machine to produce, and the steps are:

[0030] a. First prepare conventional black watermarks through design, plate making, net making, and netting

[0031] net; the part of the conventional black watermark net that is not a watermark pattern is coated with resin

[0032] Make it unable to filter water and hang paper pulp to form a color watermark net;

[0033] b. After coating, the colored pulp forms a "color watermark" of a specific pattern.

[0034] In order to ensure the smooth combination of wet paper on multiple cages of double cylinder paper machine or triple cylinder paper machine, and prevent the wet paper on the first cage from being adhered by the resin coated by the second cage (color watermark net) , take the following technical measures:

[0035] The copper mesh of the color watermarking mesh is an annealed me...

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...
