Problems solved by technology

In practice, it has been found that due to the large particles of the diffusing agent, only some printing processes such as flexo printing, gravure printing, and silk screen printing can be used for printing, and mainstream printing such as offset printing, rotary printing, and jet printing cannot be used. process to print
This makes the current printing of sawtooth subject to relatively large process and equipment limitations. In reality, many printing factories do not have the equipment to print sawtooth

Embodiment 1

[0059] Such as figure 1 As shown, a unique and sequential commodity traceability (one item, one code) two-dimensional code—code (2) is printed on each substrate (1).

[0060] In order to realize the anti-counterfeiting function, two UV ink red vertical lines can be printed on the side of the QR code——color A ink graphic (3), but do not dry and solidify it for the time being.

[0061] Immediately after the previous step, use a UV inkjet printer to print two UV ink blue horizontal lines on the undried UV ink red vertical line liquid——B color ink graphic (4), so that the blue horizontal line ink liquid and The red vertical line ink liquid partially converges→melts→diffuses→mixes colors, thereby forming a natural gradient color random pattern (5) tending to C color (purple) in the four converging areas (6).

[0062] The above-mentioned confluence→fusion→diffusion→color mixing process is basically a physical movement process, and of course a chemical formula can also be designed ...

Embodiment 2

[0068] Such as figure 2 As shown, a unique and sequential commodity traceability (one item, one code) two-dimensional code—code (2) is printed on each substrate (1).

[0069] In order to realize the anti-counterfeiting function, you can first print a 16mm×6mm UV dark red color block next to the QR code—the A-color ink graphic (3), but do not dry it for the time being.

[0070] Then, use a UV inkjet printer to print two 2mm×2mm UV ink blue ink dots on the undried UV ink red color block——B color ink graphic (4), so that the blue ink dot liquid dissolves Into the red color block liquid for color mixing and diffusion.

[0071] Immediately afterwards (preferably within 5 milliseconds), the red color block liquid, the blue ink dot liquid, and the forming random pattern (5) of natural gradient color tending to purple (ie C color) are dried and solidified.

[0072] Then, use a 10 million-pixel industrial surface-frame digital camera to zoom in and shoot (that is, macro shooting) th...

Embodiment 3

[0076] Referring to the first and second embodiments above, a natural gradient color anti-counterfeiting product is printed. Such as image 3 As shown, first print some 1.5mm wide UV ink red parallel lines on the substrate (1)——color A ink graphic (3), but do not dry and solidify the red parallel line liquid for the time being.

[0077] Next, use a UV inkjet printer to print some crossed UV ink blue parallel lines on the undried UV ink red parallel lines——B color ink graphics (4), so that the UV ink blue parallel lines liquid The liquid in parallel with the UV dark red line diffuses and mixes colors in the intersection area (6), thereby forming some random patterns of natural gradient colors tending to C color (purple) (5).

[0078] Then, dry and solidify the UV ink blue parallel line liquid, the UV ink red parallel line liquid, and the natural gradient color random pattern (5) that is forming toward C color (purple). All the other steps are the same as the above-mentioned e...

Abstract

The present invention provides a natural gradient ramp anti-fake method and a product. The method comprises the steps of: printing codes onto a printing stock, printing B-color ink liquid to A-color ink without drying to allow the A-color and B-color ink to be intersected, fused, diffused and mixed so as to form a random pattern with the gradient ramp trending to C color; and collecting personality characteristic information on the random pattern to combine and store the personality characteristic information and the codes into a cloud database to take as anti-fake files for checking true andfalse by customers. The natural gradient ramp anti-fake method and the product are zero in device investment, simple in manufacturing process and low in production cost, cannot be copied and are easyto identify.

Description

technical field [0001] The invention belongs to the field of information query anti-counterfeiting technology, in particular to an anti-counterfeiting method and product using color mixing measures to form random features of natural gradient colors that cannot be copied. Background technique [0002] "Baidu Encyclopedia": Gradient color printing reproduces the shade level of the printed image through AM dots, and its shade level depends on the size of the dots per unit area (see Figure 8 a); or reproduce the shading level of the printed image through frequency modulation dots, and the shading level depends on the number of dots per unit area (see Figure 8 b). Zooming in and observing, it can be seen that the printing gradient is composed of sparse printing dots (or ink dots) arranged one by one. [0003] During the implementation of the Chinese invention patent "Sawtooth Anti-Counterfeiting Method for Mobile Phone Identification Code (CN104794629B)", some small problems we...
