sequentially forming a first heat-sensitive ink layer and a second heat-sensitive ink layer on the surface of a base material, wherein the first heat-sensitive ink layer is distributed on the surface of the base material in a scattered manner; the second heat-sensitive ink layer covers the first heat-sensitive ink layer in the field; the first heat-sensitive ink layer shows a first color after being heated and reacted, the second heat-sensitive ink layer shows a second color different from the first color after being heated and reacted, and the color development temperature of the second heat-sensitive ink layer is higher than that of the first heat-sensitive ink layer;
and printing on the second thermosensitive ink layer by using laser, wherein the energy of the laser can enable the second thermosensitive ink layer and the first thermosensitive ink layer to generate color reaction, so that the identification code of the second color is formed on the second thermosensitive ink layer, and the interference background of the first color at the edge of the identification code is formed on the first thermosensitive ink layer.
The color of the surface of the substrate material is white, the second color is black, and the first color is gray.
The color development temperature of the first heat-sensitive ink layer is 110-130 ℃.
The developing temperature of the second heat-sensitive ink layer is 60-90 ℃.

The identification code manufactured by the printing method of the identification code of the identification device is used for identification, and the identification device is provided with a filter which can filter the first color but can not filter the second color.
In the process of laser coding, the second heat-sensitive ink layer positioned on the surface layer is heated to the color development temperature node to develop color to form an identification code pattern, and simultaneously the heat is conducted to the first heat-sensitive ink layer positioned below the second heat-sensitive ink layer, because the color development temperature of the first heat-sensitive ink layer is lower than that of the second heat-sensitive ink layer, more area on the second heat-sensitive ink layer is heated to the color development temperature through the diffusion of the heat, in addition, because the second heat-sensitive ink layer is provided with regular lattice-shaped patterns, a saw-toothed interference background with lighter color than the identification code is formed around the identification code pattern, the identification code can not be read, the anti-theft brush function is realized, because the shape shown by the identification code depends on the lattice spacing and the shape of the lattice pattern and the color development temperatures of the first heat-sensitive ink layer and the second heat-sensitive ink layer, other people are difficult to imitate, the anti-counterfeiting effect is achieved, during identification, the code scanning can be completed only by filtering the background color block on the identification code pattern by using a filter device which can filter the first color but can not filter the second color, and the code scanning process is more convenient and faster than the existing identification code authentication mode adopting anti-counterfeiting and anti-theft brushing means.

Detailed Description
The present invention will be more clearly and completely described in the following description of preferred embodiments thereof, taken in conjunction with the accompanying drawings.
As shown in fig. 1 to 3, a method for printing and identifying an identification code includes the following steps:
(1): sequentially forming a first heat-sensitive ink layer 1 and a second heat-sensitive ink layer 2 on the surface of a base material 3, wherein the first heat-sensitive ink layers 1 are distributed on the surface of the base material 3 in a scattered manner; the scattered distribution is represented as a regular lattice pattern, and the second thermosensitive ink layer 2 covers the first thermosensitive ink layer 1 in the field; the first thermosensitive ink layer 1 shows gray after being heated and reacted, the second thermosensitive ink layer shows black after being heated and reacted, the color development temperature of the second thermosensitive ink layer is 130 ℃, and the color development temperature of the first thermosensitive ink layer is 80 ℃;
(2): printing on the second heat-sensitive ink layer 2 by using laser, wherein the energy of the laser can enable the second heat-sensitive ink layer 2 and the first heat-sensitive ink layer 1 to generate a color reaction, so that a black identification code is formed on the second heat-sensitive ink layer 2, and a gray interference background located at the edge of the identification code is formed on the first heat-sensitive ink layer 1.
The printing process of the identification code is as shown in fig. 3, laser beams irradiate on the first thermosensitive ink layer 1 and heat the first thermosensitive ink layer 1 to enable the first thermosensitive ink layer to develop color, identification code patterns are generated, heat conduction is conducted to the second thermosensitive ink layer 2 due to heat conduction effect, the color development temperature of the second thermosensitive ink layer is lower than that of the first thermosensitive ink layer 1, the second thermosensitive ink layer has more areas than that of the first thermosensitive ink layer and is heated to the color development temperature, a gray sawtooth-shaped background color lump is formed in the edge area of the identification code, and therefore the identification code cannot be directly read.
