Description
Technical Field
The invention relates to the field of color printing, in particular to a method for manufacturing color watermark anti-counterfeiting paper.
Background
The watermark anti-counterfeiting paper is the most widely applied anti-counterfeiting paper at present, and the banknote paper is a typical representative of the watermark anti-counterfeiting paper. Most of the traditional watermark anti-counterfeiting paper is white paper, and a small amount of the traditional watermark anti-counterfeiting paper is colored paper. Whether white paper or colored paper, its technical characteristics are: the watermark part and the paper part are composed of paper pulp with the same color. Although the paper has the anti-counterfeiting function, in the information age of rapid development of science and technology, the anti-counterfeiting strength of the anti-counterfeiting paper is insufficient, so that the phenomena of counterfeit money and invoice are caused occasionally, and the economic order and the life of people are disturbed.
Disclosure of Invention
In order to solve the problems, the invention provides a method for manufacturing color watermark anti-counterfeiting paper, which comprises the following steps:
a manufacturing method of color watermark anti-counterfeiting paper comprises the following steps:
step 1, the color watermark anti-counterfeiting paper comprises a first basic layer consisting of white paper pulp, a second hollowed layer consisting of white paper pulp, a third color watermark layer consisting of color paper pulp and a fourth basic layer consisting of white paper pulp; after the second hollowed-out layer is hollowed out aiming at the pattern to be printed, the second hollowed-out layer is immersed into a solution consisting of isolation resin, the solution is dried, then the first base layer and the second hollowed-out layer are compounded at the net part of a cylinder paper machine to form first color printing paper, the back surface of the first color printing paper is a basic white structure, the front surface of the first color printing paper is a white structure with the inside being basic white and the outside being covered with the isolation resin;
and 3, drying the second color printing paper, and compounding the color surface of the second color printing paper and the fourth base layer in the net part of the cylinder paper machine correspondingly to form a finished product.
Preferably, the release resin solution is formed by mixing nitro varnish or polyurethane paint with other organic solvents.
Preferably, the thickness of the first base layer is 60g/m2-150g/m2The thickness of the second hollow-out layer is thinner than that of the first base layer and is 40g/m2-50g/m2The thickness of the fourth base layer is 60g/m2-150g/m2。
Preferably, after the colored paper pulp is added into the hollow-out patterns in the step 2, a transparent protective layer is coated, and the transparent protective layer is flush with the surface of the second hollow-out layer.
Has the advantages that: compared with the existing products in the market, the color paper pulp is coated in the hollow pattern of the second hollow layer, and the outer surface of the second hollow layer is flat, so that the situation that the color paper pulp protrudes outwards does not exist, the anti-counterfeiting paper is convenient to compound, the phenomena of bubbles and the like do not exist, and the surface is flat and has better touch feeling; the printed color watermark pattern has clear and abnormal boundary and no blurring phenomenon.

Detailed Description
The invention will be further illustrated with reference to the following examples and figures 1-2.
Example 1: the color watermark anti-counterfeiting paper comprises a first base layer 1 consisting of white paper pulp, a second hollow layer 2 consisting of white paper pulp, a third color watermark layer 3 consisting of color paper pulp and a fourth base layer 4 consisting of white paper pulp. The first base layer 1 has a thickness of 60g/m2-150g/m2The thickness of the second hollow-out layer 2 is thinner than that of the first base layer 1, and is 40g/m2-50g/m2The thickness of the fourth base layer 4 is 60g/m2-150g/m2。
A manufacturing method of color watermark anti-counterfeiting paper comprises the following steps:
step 1, after a second hollowed-out layer 2 is hollowed out aiming at a pattern to be printed, immersing the second hollowed-out layer 2 into a solution composed of isolation resin, drying, and then compounding a first base layer 1 and the second hollowed-out layer 2 at a net part of a cylinder paper machine to form first color printing paper, wherein the back surface of the first color printing paper is a basic white structure, the front surface of the first color printing paper is a white structure with the inside being basic white and the outside being covered with the isolation resin;
and 3, drying the second color printing paper, and combining the color surface of the second color printing paper and the fourth base layer 4 in the net part of the cylinder mould paper machine correspondingly to form a finished product.
