Abstract
The present invention discloses a method for making watermark anti-counterfeiting paper, particularly a method for making high-quantitative watermark anti-counterfeiting paper. The present invention mainly aims to solve the problems of watermark paper with poor high-quantitative light permeability and poor anti-counterfeiting property in the prior art and provides the method for making high-quantitative watermark anti-counterfeiting paper. The method comprises the steps of designing a watermark, carving a watermark module, making a net, preparing paper pulp, copying paper, etc., wherein when the watermark is designed, the height of a watermark plate is 1.0mm to-2.5mm and the slope grade of the watermark plate is 5 DEG to 20 DEG; when the watermark plate is craved, the watermark plate is craved by a spherical cutter with the height of 1.0mm to-2.5mm and the slope grade of 5 DEG to 20 DEG. By the application of the method, the high-quantitative watermark anti-counterfeiting paper with the quantitativeness of 120 to 220 g/m<2> is made, which is not combined and has the advantages of good light permeability and high anti-counterfeiting performance.
Description
Technical field
The present invention relates to a kind of preparation method of water-mark fake-proof paper, particularly a kind of preparation method of high quantitative watermark anti-forge paper.
Background technology
Watermark is that current most countries applies to a kind of main false proof means in the circulating paper money, the making of watermark paper higher, professional very strong, the characteristics such as technology is complicated of difficulty that possess skills, and at present in industry, the main flow of watermark paper is quantitatively at 80～90g/m
2Between, can not satisfy various informative product demand far away, and so-called high quantitative watermark paper on the market is difficult for the printing opacity observation by low quantitative watermark paper and the compound generation of presspaper, anti-counterfeiting performance is not high, and directly by the production of paper machine quantitatively at 120～220g/m
2Between high quantitative watermark anti-forge paper, the difficulty that has plate-making and copy paper has not yet to see relevant report.
Summary of the invention
The objective of the invention is deficiency, provide that a kind of printing opacity observes that property is good, anti-counterfeiting performance is high, the preparation method of non-compound high quantitative watermark anti-forge paper at above-mentioned high quantitative watermark paper making method.
The objective of the invention is to realize by following technical proposals:
The preparation method of high quantitative watermark anti-forge paper, comprise watermark design, engraving watermark masterplate, make net, prepare paper pulp, copy step such as paper, the height of watermark when design design watermark version be 1.0mm～-2.5mm between, the gradient is between 5 °～20 °, when engrave with spherical graduating with cutter system height be 1.0mm～-2.5mm between, the gradient is the watermark version between 5 °～20 °.
When drying in the described paper-making process, the production line speed of service is 28 meters/minute～38 meters/minute.
The cone angle of the spherical cutter of engraving usefulness is 20 °～45 °.
Described water marked paper is quantitatively at 120～220g/m
2Between.
The invention has the beneficial effects as follows, the height of watermark when design design watermark version 1.0mm～-2.5mm between, the gradient is between 5 °～20 °, use special spherical graduating with cutter system to meet the watermark version that as above requires then when engrave, the watermark version of this structure has guaranteed light transmission and the anti-counterfeiting performance of watermark in high quantitative watermark anti-forge paper of making; The production line speed of service in when oven dry can make high quantitative water-mark fake-proof paper fully dry at 28 meters/minute～38 meters/minute in the control paper-making process, meets the demands with the adhesive force of watermark.As seen adopt the high quantitative watermark anti-forge paper preparation method of such scheme can make high quantitative watermark anti-forge paper have printing opacity and observe that property is good, anti-counterfeiting performance is high, non-compound advantage.

Embodiment 2: the step by embodiment 1 is operated, wherein, height-the 1.0mm of design watermark masterplate during the watermark design, the gradient is 15 °, with cone angle as shown in Figure 3 is that 30 ° spherical cutter is carved out watermark masterplate as shown in Figure 2, height-the 1.0mm of watermark masterplate, the gradient is 15 °, on copper mesh, suppress watermark areas with this masterplate, prepare paper pulp then, and paper pulp put in the paper pulp pond copy paper, in the paper-making process during oven dry running speed of control production line at 35 meters/minute, the dehydration that is beneficial to the quantitative water marked paper of height parches, and the water-mark fake-proof paper of producing is quantitatively at 150g/m
2
Embodiment 3: the step by embodiment 1 is operated, wherein, height-the 2.5mm of design watermark masterplate during the seal design, the gradient is 20 °, with cone angle as shown in Figure 3 is that 45 ° spherical cutter is carved out watermark masterplate as shown in Figure 2, height-the 2.5mm of watermark masterplate, the gradient is 20 °, on copper mesh, suppress watermark areas with this masterplate, prepare paper pulp then, and paper pulp put in the paper pulp pond copy paper, in the paper-making process during oven dry running speed of control production line at 28 meters/minute, the dehydration that is beneficial to the quantitative water marked paper of height parches, and the water-mark fake-proof paper of producing is quantitatively at 220g/m
