Problems solved by technology

[0002] Chinese patent document CN202563817U discloses a "dynamic color code anti-counterfeiting mark", which designs 10-21 anti-counterfeiting digital Arabic characters into randomly changing colored characters (i.e. variable information), in order to increase the difficulty of copying and counterfeiting
[0003] Chinese patent document CN2476070Y discloses a kind of "password graphic anti-counterfeiting marker", which has printed some random graphics (i.e. variable information) on the anti-counterfeiting mark, in order to increase the difficulty of copying and counterfeiting
This document provides a method to block the loopholes in the code anti-counterfeiting technology ("a house thief is hard to prevent"), but the implementation is relatively complicated, which increases the difficulty and cost of printing

Embodiment 1

[0081] The anti-counterfeiting method of the zigzag code of the present invention is used to produce an electronic drug supervision code.

[0082] Such as figure 1 , Figure 5 , Figure 9 As shown, on the production line, a printing machine 1 such as a UV inkjet printer is used to spray code on the conveyed substrate 2, thereby producing an electronic drug supervision code with a jagged edge 6——code 4 .

[0083] In order to make the bars and characters of the drug electronic regulatory code slightly deformed, random personalized jagged edges 6 are produced. An upper wind gun can be set up between the inkjet printing machine 1 and the UV drying lamp 8, and the strong wind 11 can be blown to the printed wet electronic ink 3, and the bars and characters of the drug electronic supervision code can be driven by the wind pressure. Casting micro-deformation occurs. But, the jagged edge 6 of the pharmaceutical electronic supervision code made in this way has the disadvantages of g...

Embodiment 2

[0090] The anti-counterfeiting method of the zigzag code of the present invention is used to produce an electronic drug supervision code.

[0091] Such as figure 1 , figure 2 , Figure 4 , Figure 10 As shown, on the printing line, an inkjet printing machine 1 such as a UV inkjet printer is used to spray code on a certain substrate 2 conveyed, and the printed electronic ink 3 is used as cold hot glue, and the silver laser cold hot film 10 Lay it on, and then peel it off after being rolled by the pressure roller 9, so that the metal (plating) layer 7 is transferred to the electronic ink 3, and the drug electronic supervision code with a clear (no gradient) sawtooth edge 6 is produced. The drug electronic supervision code produced in this way has the following advantages: the jagged edge 6 has a clear outline, no gradient color, easy to automatically identify the anti-counterfeiting query APP, and the surface of the code 4 has a metallic luster, and even personalized laser g...

Embodiment 3

[0098] The zigzag code anti-counterfeiting method of the present invention is used to produce a two-dimensional code whose content is the website address and serial number of a computer anti-counterfeiting query system database. For example, the content is the QR code of http: / / t.ppk365.com / 436579352077, etc.

[0099] Such as Figure 5 , Figure 6 , Figure 9 As shown, on the printing line, an inkjet printer 1 such as a UV inkjet printer is used to spray code on the conveyed substrate 2 to produce a two-dimensional code with jagged edges 6 —code 4 .

[0100] In order to promote the casting and micro-deformation of the two-dimensional code, random personalized jagged edges 6 are produced. An upper air gun can be installed between the inkjet printing machine 1 and the UV drying lamp 8, and the strong wind 11 can be blown to the printed electronic ink 3, and the two-dimensional code can be pushed by the external force through the wind pressure to produce microscopic out of sh...

Abstract

The invention discloses a micro-pattern anti-fake method, which comprises the following steps: a) printing to form a coded mark or a graphic mark with a randomly serrated edge; b) enlarging and photographing the printed coded mark or graphic mark to obtain the picture showing the serration characters of the coded mark or the graphic mark; and c) storing the picture showing the serration characters of the coded mark or the graphic mark as anti-fake feature recording information. Firstly, the coded mark or the graphic mark is compared. If not consistent, a conclusion report of a faked product is issued; if the coded mark or the graphic mark is consistent, then the picture showing the serration characters of the coded mark or the graphic mark is compared. The present invention stores picture showing the serration characters of the coded mark or the graphic mark as anti-fake feature recording information by printing the coded mark or graphic mark with the serrated edge, so as to effectively prevent the stolen anti-fake data from being used for fraud and hardly increases production and printing costs, and the process is simple and easy to be promoted.

Description

technical field [0001] The invention relates to an anti-counterfeiting method, in particular to a sawtooth code anti-counterfeiting method. Background technique [0002] Chinese patent document CN202563817U discloses a kind of " dynamic color code anti-counterfeiting mark ", and it designs 10-21 anti-counterfeiting digital Arabic characters into randomly changing color characters (ie variable information), in order to increase the difficulty of copying and making fakes. When checking and verifying, the data is completely consistent, and the color of each character is also consistent with the character feature color recorded in the database of the computer anti-counterfeiting query system, so that the logo can be deemed as true. [0003] Chinese patent document CN2476070Y discloses a "cipher graphic anti-counterfeiting mark", which has printed some random graphics (ie variable information) on the anti-counterfeiting mark, in order to increase the difficulty of copying and mak...
