Problems solved by technology

[0002] During the implementation of the Chinese invention patent "Sawtooth anti-counterfeiting method for mobile phone identification code (CN104794629B)" and the Chinese utility model patent "Sawtooth code anti-counterfeiting printed matter (CN204833342U)", we encountered such a quality control (quality control) problem: QR codes, etc. The random sawtooth generated by variable encoding makes it very difficult to control the printing quality
Either the jaggedness on the QR code is too large, too dense, and too uneven, which makes it difficult for mobile phones to read the QR code, resulting in unqualified printing quality of the QR code, resulting in a large amount of printing waste and economic losses; or the QR code is too small, Too little, no sawtooth on the edge, resulting in unqualified printing quality of sawtooth, causing a lot of printing waste and economic loss
All in all, the quality of random sawtooth generated by variable codes such as two-dimensional codes is very difficult to control during the manufacturing process. Either the sawtooth is too large or too small, or the sawtooth is too small, too few, or too uneven, which often leads to poor printing quality of the substrate. Qualified, resulting in a large number of substrate waste and economic losses

Embodiment 1

[0061] Such as figure 1 , figure 2 As shown, on the production line, a UV inkjet printer is used to inkjet the substrates (1) such as medicine boxes conveyed in the forward direction (10).

[0062] In order to anti-counterfeit the medicine box, a unique two-dimensional code can be compiled for each medicine box, for example: the two-dimensional code whose information content is http: / / m-texture.com / pg / p / 0106903148093603 / 38974203238148 / iIFnIz Code - variable code (2). Generate a QR two-dimensional code pattern of 12mm×12mm from the information content, and print it on the designated area on the medicine box. Use 230g / m2 due to the kit 2 National standard cardboard, the surface of national standard cardboard has non-diffusion characteristics, therefore, its entire paper surface can be called non-diffusion area (6).

[0063] In order to promote the rapid formation of random serrations (4), a 14mm×7mm rectangular diffusion coating (7) can be printed in advance on the partial ...

Embodiment 2

[0067] Such as image 3 , Figure 4As shown, on the production line, the UV inkjet printer is used to transport the 28g / m 2 Printing materials (1) such as typed paper drug instructions are sprayed.

[0068] In order to prevent counterfeiting of the drug instructions, a QR code can be compiled for each drug instruction, for example: the QR code with the information content http: / / m-texture.com / pg / p / 0106903148093603 / 38974203238148 / iIFnIz—— Variable encoding (2). Generate a QR two-dimensional code pattern of 12mm×12mm from the information content, and print it on the designated area on the drug instruction sheet. Since the surface of the typing paper already has good diffusion properties, the entire paper surface is a diffusion area (5).

[0069] In order to avoid sawtooth formation at the edge of the two-dimensional code, a rectangular non-diffusion coating (8) of 14mm×14mm can be printed on the partial surface of the drug insert in advance. The non-diffusion coating (8) ca...

Embodiment 3

[0073] The rectangular frame (12) in the above-mentioned embodiment one and two is replaced by Figure 5 Three vertical lines (11) and three horizontal lines (9) are shown.

Abstract

The invention provides a local diffusion-sawtooth anti-fake print. The print is provided with a diffusion area, an indiffusion area, a diffusion coating or an indiffusion coating. A fixed image-text ink layer edge rapidly diffuses so as to form an obvious random sawtooth under an effect of a diffusion area surface tension. A height of the sawtooth is greater than a height of a sawtooth on a two-dimensional code ink layer edge. A sawtooth density is greater than a sawtooth density of the two-dimensional code ink layer edge. The print is easy to carry out quality control, a defective index can be reduced, and a lot of a lot of printing wastes and economic losses can be avoided.

Description

technical field [0001] The invention belongs to the technical field of printing anti-counterfeiting, and particularly relates to a specific improvement application technology of the Chinese invention patent "Sawtooth anti-counterfeiting method for mobile phone identification code (CN104794629B)" and the Chinese utility model patent "Sawtooth code anti-counterfeiting printed matter (CN204833342U)" - local diffusion sawtooth Security prints. Background technique [0002] During the implementation of the Chinese invention patent "Sawtooth anti-counterfeiting method for mobile phone identification code (CN104794629B)" and the Chinese utility model patent "Sawtooth code anti-counterfeiting printed matter (CN204833342U)", we encountered such a quality control (quality control) problem: QR codes, etc. The random sawtooth generated by variable encoding makes it very difficult to control the printing quality. Either the jaggedness on the QR code is too large, too dense, and too unev...
