Embodiment 1

[0041] figure 1 It is a printed matter (1) of an existing product, and at least a blank area (3) of h=0-1mm is reserved near the two-dimensional code (2).

[0042] Such as figure 2 shown in figure 1 Some randomly distributed ink dots (4) with a diameter of 0.08 mm are printed in the blank area (3). The coverage (ie distribution density) of ink dots (4) is controlled in the range of 30-50%, in other words, 70-50% of the area is still white. It is best to use the diffusion agent in the background technology "Mobile Phone Identification Code Sawtooth Anti-counterfeiting Method (CN104794629B)", pre-print a diffusion agent coating in the blank area (3) in advance, and promote the ink dots printed on the diffusion agent coating (4) random diffusion (including reverse diffusion, that is, contraction), forming a zigzag edge (6).

[0043] The two-dimensional code (2) printed on each printed matter (1) should be a unique code.

[0044] After the sawtooth edge (6) is dried, cured, ...

Embodiment 2

[0048] Such as image 3 shown in figure 1 Print some line segments (5) with a width of 0.1mm x a length of 1.5mm in the blank area (3). The coverage (ie distribution density) of the line segment (5) is controlled within the range of 20-35%, in other words, 80-65% of the area is still bare. Preferably adopt the diffusing agent in the background technology " mobile phone identification code zigzag anti-counterfeiting method (CN104794629B) ", pre-print a diffusing agent coating in the blank area (3) in advance, impel the line segment ( 5) Random diffusion (including reverse diffusion, that is, shrinkage), forming a zigzag edge (6).

[0049] The two-dimensional code (2) printed on each printed matter (1) should be a unique code.

[0050] After the sawtooth edge (6) is dried, cured, and shaped, enlarge and shoot the sawtooth edge (6) to collect microscopic feature information of the serrated edge (6); and store the microscopic feature information and its two-dimensional code (2)...

Abstract

The invention belongs to a code edge sawtooth anti-counterfeiting method, which comprises the following steps: printing a two-dimensional code on a printed matter, and printing some sparse ink dots or / and line segments in a blank area with the width of 0-1.5 mm near the two-dimensional code; promoting the ink forming the ink dots or / and the line segments to randomly diffuse to form sawtooth edges;amplifying and shooting the two-dimensional code and the sawtooth edge to obtain microscopic feature information of the sawtooth edge; and correspondingly storing the obtained microscopic feature information and the two-dimensional code into an anti-counterfeiting inspection system database to serve as an anti-counterfeiting feature information file. According to the method, the code edge is ingeniously utilized, the sawtooth edge formed by the ink dots or / and the line segments on the code edge can be used as an anti-counterfeiting feature. The trouble of revision is avoided, two-dimensionalcode reading interference is avoided, and microscopic feature information of the sawtooth edge can be conveniently acquired through code scanning.

Description

technical field [0001] The invention belongs to the field of information query anti-counterfeiting technology, and specifically relates to an improved application technology of Chinese invention patents "Sawtooth Anti-counterfeiting Method for Mobile Phone Identification Code (CN104794629B)" and "Anti-counterfeiting Method and Printed Matter of Overlimited Ink Dots (CN109711511A)". Background technique [0002] The size of the sawtooth required in the specification of the Chinese invention patent "Sawtooth Anti-Counterfeiting Method for Mobile Phone Identification Code (CN104794629B)" is "0.3mm(H)×0.3mm(W)~0.05mm(H)×0.05mm(W)". Serrations are large serrations. [0003] The "mobile phone identification code sawtooth anti-counterfeiting method (CN104794629B)" includes printing codes or / and graphics on the substrate, which is characterized in that it includes: printing a code or / and picture that randomly generates personalized sawtooth edges through process design Among them, ...
