Embodiment 1

[0045] figure 1 It is the printed matter (1) of the current product, and near its two-dimensional code (2), at least a blank area (3) of h=0-1mm is reserved, that is, the code edge described in the present invention.

[0046] Such as figure 2 shown in figure 1 Some randomly distributed ink dots (4) with a diameter of 0.4 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. Preferably adopt the diffusing agent in the background technology " mobile phone identification code zigzag anti-counterfeiting method (CN104794629B) ", pre-print a diffusing agent coating (7) in the blank area (3) in advance, impel spray printing on the diffusing agent coating ( 7) The ink dots (4) on the top diffuse randomly (including reverse diffusion, that is, shrinkage), forming a sawtooth edge (6).

[0047] The two-dimensional code (2) printed on each printed matter (1)...

Embodiment 2

[0052] 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 (7) in the blank area (3) in advance, impel spray printing on the diffusing agent coating ( The line segment (5) on 7) diffuses randomly (including back-diffusion, that is, shrinks), forming a zigzag edge (6).

[0053] The two-dimensional code (2) printed on each printed matter (1) should be a unique code.

[0054] 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...

Embodiment 3

[0058] Such as Figure 4 As shown, in the blank area (3) 0.5-1.5mm away from the edge of the two-dimensional code (2), print an ink dot (4) with a diameter of 0.3-0.4mm at an interval of 0.5-1mm, so that the ink dot (4) forms A dotted frame around the QR code (2). 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.

[0059] The two-dimensional code (2) printed on each printed matter (1) should be a unique code.

[0060] 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) correspondingly Filed in the database of the anti-counterfeiting inspection system connected to the Internet as an anti-counterfeiting characteristic information file.

[0061] During inspection, consumers use their smartphones...

Abstract

The invention belongs to a code edge sawtooth anti-counterfeiting method, which comprises the following steps of: printing a two-dimensional code on printed matter, and printing some sparse ink dots or / and line segments in a blank area with the width of 0-2mm 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-dimensional code 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 the improved application technology of Chinese invention patents "Sawtooth Anti-counterfeiting Method for Mobile Phone Identification Code (CN104794629B)" and "Anti-counterfeiting Method and Printed Matter Over Limit 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 "sawtooth anti-counterfeiting method for mobile phone identification code (CN104794629B)" includes printing codes or / and graphics on the substrate, which is characterized in that it includes: random generation of personalized zigzag-edged codes or / and graphics by process design printing; Among them, the size...
