Problems solved by technology

However, in the application practice, some shortcomings are encountered: printing or packaging paper with structural texture (fiber) and meeting the requirements must be specially ordered, and colored fibers pollute the paper machine pipeline during papermaking
Although these texture anti-counterfeiting materials overcome the above-mentioned deficiencies, their textures are still the "material internal structural characteristics inherent in the carrier" described in the "structural texture anti-counterfeiting method (CN99801139.8)", and have not broken through the "structural texture anti-counterfeiting method (CN 99801139.8)". )" about texture limitations
[0004] In particular, the current textured anti-counterfeiting paper technology typified by "A Fiber Anti-counterfeiting Fabrication Method for Paper (CN200810198662.9)" has changed the paper's The inherent characteristics of the paper have caused many new problems: such as paper hardening, thickening, brittleness, poor ink retention, and increased costs.

Embodiment 1

[0026] Embodiment one: if figure 1 , figure 2 Shown, choose a 80 g / m 2 The white coated paper is used as the carrier layer (1).

[0027] Such as Figure 6 As shown, select a 20-micron thick PET golden high-temperature-resistant film, and coat a transparent hot-melt adhesive layer with a thickness of 5 microns (melting point is 80-120 ° C) on both sides of the front and back as the adhesive layer ( 3). After drying, use a shredder to cut it into strips of 0.2mm×2mm——self-adhesive sheet-like golden fiber (2).

[0028] Use a powder spreader to evenly, disperse and randomly sprinkle 2mm×0.2mm self-adhesive flake golden fibers (2) to 80g / m 2 on the white coated paper carrier layer (1).

[0029] Finally, roll the coated paper with the anti-adhesive hot roller on the heat-pressing compound machine to melt the hot-melt adhesive (adhesive) layer on the self-adhesive sheet-shaped golden fiber (2), and bond the fiber (2) to the copper plate After cooling the surface of the paper,...

Embodiment 2

[0031] Embodiment two: if image 3 , Figure 4 , Figure 5 Shown, select 80 g / m 2 The white coated paper is used as the carrier layer (1).

[0032] Such as Figure 7As shown, select a red round filament chemical fiber (2) with a diameter of 50 microns and a length of 3 mm. After being soaked in a UV transparent adhesive, it is scooped up to wrap a layer of UV transparent adhesive (3) on its surface, so as to make a UV self-adhesive fiber (2).

[0033] Spray the UV self-adhesive fiber (2) uniformly, dispersedly and randomly to 80 g / m using a sprayer 2 on the surface of the white coated paper carrier layer (1) and compacted.

[0034] Finally, irradiate the surface of the coated paper with a UV drying lamp, so that the UV self-adhesive fiber (2) is firmly bonded to the surface of the coated paper.

[0035] Since the UV self-adhesive fiber (2) is bonded to the surface of the coated paper by its own UV adhesive layer (3), the surface of the coated paper is not bonded to the ...

Abstract

The invention provides a texture counterfeiting printed matter with fibers adhered on the surface. The fibers the surfaces of which are covered by adhesive layers are adhered on the surface of paper; and random distribution characterize information of the fibers is scanned and acquired, and then stored into a computer counterfeiting inquiring system database of a telephone network or internetwork so as to be convenient for people to check true or false. The invention has the advantages of maintaining paper inherent characteristic, enabling the paper not to become hard, thick and crisp and the inking property of the paper not to become poor, and greatly lowering the cost. The invention also breaks through the limit of the background technology about texture, and provides another new technical means for counterfeiting by using the fibers.

Description

technical field [0001] The invention relates to the field of structural texture anti-counterfeiting technology, in particular to a new texture anti-counterfeiting technology that breaks through the limitation of "structural texture anti-counterfeiting method (CN 99801139.8)". Background technique [0002] The "structural texture anti-counterfeiting method (CN99801139.8)" applied by the inventor has obtained Chinese patents, US patents (certificate number US6623041), Russian patents (certificate number 2202127), Korean patents (certificate number 0419436), Vietnamese patents (certificate 3347) and other international patents (PCT / CN99 / 00102). It selects a material (carrier) with a clear random structure texture (such as the texture formed by fibers) to make an anti-counterfeiting mark; and prints a unique identification number; scans and collects the random structure texture feature information on the mark, as The anti-counterfeiting identification feature information (that ...
