Problems solved by technology

[0003] The research shows that after the counterfeiter obtains the sawtooth image of the code / graphic by means of high-definition scanning, he can print and reproduce very realistic sawtooth through offset printing and other plate printing processes, making it more difficult for the software identification of the anti-counterfeiting inspection system, resulting in Decrease in inspection accuracy

Embodiment 1

[0024] Use self-adhesive fragile paper (the best paper thickness is 0.15mm) as substrate 1. Such as figure 1 , figure 2 As shown, next to the code 2 in the form of a two-dimensional code, laser engrave some grooves 3 with a depth of 0.05 mm to 0.1 mm and a width of 0.1 mm to 0.2 mm. For example, the grooves 3 are designed as geometric figures such as parallel lines with a spacing of 0.5mm. It is best to design the width of the grooves 3 according to the current standard of one-dimensional barcode bars, and arrange the grooves 3 in parallel to form a one-dimensional barcode.

[0025] Use the inkjet printer to print the ink on the substrate 1, so that the ink forms the designed vertical bar and other graphic layers 4; and make some ink fall into the groove 3, and randomly diffuse and elongate in the groove 3, Serrations 5 in the groove are formed.

[0026] The graphic 4 and the sawtooth 5 in the ditch are collected and stored in the cloud database as anti-counterfeit feature...

Embodiment 2

[0028] Such as image 3 As shown, a grooved serrated anti-counterfeiting mark manufactured by printing in the above example, the groove edge line 7 is aligned with the groove inner serrated edge line 6, that is, the groove edge line 7 is aligned with the groove inner serrated edge line 6 The docking is neat and will not be misplaced. In other words, to copy counterfeit goods, there must be such Figure 4 As shown, the groove edge line 7 is misaligned with the zigzag edge line 6 in the groove.

[0029] The graphic layer 4 of the present invention can be any characters, graphics, lines, ink dots, etc. made of ink.

Abstract

The invention provides an in-trench sawtooth anti-counterfeiting method which comprises the following steps: forming trenches in a printing stock; printing ink codes/images and texts on a printing stock in a jet printing mode, wherein some ink falls into the trenches and diffuses and extends along the trenches, and sawtooth in the trenches are formed. and storing the sawtooth feature information in a cloud database, so that the public can check authenticity by using a photographing mobile phone. The product using the in-trench sawtooth anti-counterfeiting method cannot be copied, and is easy to identify and high in query accuracy rate.

Description

technical field [0001] The invention belongs to the field of information query anti-counterfeiting technology, and in particular relates to an improved technology of the Chinese patent "Sawtooth Anti-counterfeiting Method for Identification and Code of Mobile Phone (CN104794629B)" - an anti-counterfeiting method of sawtooth in a groove. Background technique [0002] The Chinese patent "Sawtooth Anti-Counterfeiting Method for Mobile Phone Identification Code (CN104794629B)" authorizes a technical solution for anti-counterfeiting by using sawtooth, which includes printing ink codes / graphics on the substrate, so that the ink codes / graphics are randomly diffused and personalized Sawtooth; zoom in on the printed ink code / image to obtain the zigzag feature information and coding information; store the zigzag feature information and corresponding coding information obtained through zooming in on the anti-counterfeiting inspection system database connected to the Internet— —Cloud da...
