Method for printing identification code and method for identifying identification code

Abstract

A method for printing an identification code comprises the steps of: covering a surface of a base material with a second temperature-sensitive ink layer which is provided with a pattern and gray, covering the second temperature-sensitive ink layer with a first temperature-sensitive ink layer which is black, and setting the color development temperature of the first temperature-sensitive ink layer is higher than that of the second temperature-sensitive ink layer, irradiating the first temperature-sensitive ink layer and the second temperature-sensitive ink layer with a laser beam to move a laser beam printing pattern in accordance with the arrangement rule of the identification code pattern. A method for identifying the identification code using the printing method comprises the following steps: a device with a gray color filter is used to identify an identification code and read an identification code, the identification code printed with the scheme has the anti-theft brush function and the anti-counterfeit function at the same time and is easy and quick to read.

Description

technical field [0001] The invention relates to the field of labels, in particular to a method for printing and identifying identification codes. Background technique [0002] With the popularization of mobile devices and the development of big data platforms, identification code technology has become an indispensable part of daily life. However, if the identification code is not protected, it may be easily stolen or forged. This will not only affect Consumers cause economic losses, and at the same time bring damage to the interests and reputation of businesses. Laser printing is currently a very efficient printing method. color rendering temperature node, so as to achieve the effect of displaying pattern text, but the identification code directly printed by laser does not have anti-theft and anti-counterfeiting, and often needs further anti-counterfeiting and anti-theft anti-swiping treatment.

[0002] With the popularization of mobile devices and the development of big data platforms, identification code technology has become an indispensable part of daily life. However, if the identification code is not protected, it may be easily stolen or forged. This will not only affect Consumers cause economic losses, and at the same time bring damage to the interests and reputation of businesses. Laser printing is currently a very efficient printing method. color rendering temperature node, so as to achieve the effect of displaying pattern text, but the identification code directly printed by laser does not have anti-theft and anti-counterfeiting, and often needs further anti-counterfeiting and anti-theft anti-swiping treatment. The existing method mainly covers the surface with a Layer scratch card, printing the identification code on the reverse side of the label paper, covering the identification code with a layer of anti-counterfeiting coating to protect the identification code, these processes need to consume a certain amount of man-hours, reducing production efficiency When coding, due to the influence of anti-theft brushing and anti-counterfeiting measures, the identification code is often hidden in a hidden place, and the label paper needs to be destroyed to read, or the scratch layer needs to be scraped off with the help of tools to read. In the case of large-scale reading of identification codes, such as reading the goods information when a supermarket purchases goods, the anti-theft and anti-counterfeiting measures of the identification code will affect the reading efficiency
