technical field

The invention relates to the field of anti-counterfeiting technology, in particular to a method for manufacturing an infrared anti-counterfeiting label and a product with an infrared anti-counterfeiting label.

Background technique

Anti-counterfeiting of products is necessary for product technology and commercial success. At present, infrared anti-counterfeiting technology has been widely used. The existing infrared anti-counterfeiting technology uses special infrared anti-counterfeiting ink to print anti-counterfeiting marks, which can generate visible light under the irradiation of infrared light to display anti-counterfeiting patterns or characters.

In the process of realizing the present invention, the inventors found that because the existing infrared anti-counterfeiting technology requires the use of special infrared anti-counterfeiting ink, the cost of making anti-counterfeiting marks is relatively high, and the manufacturing method of infrared anti-counterfeiting ink is also relatively complicated.

Detailed ways

In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

In order to solve the problem that the existing infrared anti-counterfeiting technology requires the use of special ink, the production method is complicated and the cost is high, the embodiment of the present invention provides a method for manufacturing an infrared anti-counterfeiting label and a product with an infrared anti-counterfeiting label.

As shown in Figure 1, the manufacturing method of the infrared anti-counterfeiting label provided by the embodiment of the present invention includes:

An anti-counterfeit pattern with the same color as the base layer under visible light is coated on the preset base layer, and the blackness of the material used for coating the anti-counterfeit pattern is different from that of the base layer material.

In the embodiment of the present invention, the blackness refers to the ratio of the radiation ability of a gray body at a certain temperature to the radiation ability of a black body at the same temperature. Objects with an absolute temperature above 0 Kelvin emit infrared radiation, a form of invisible light. The infrared radiation ability of various materials is expressed by blackness, and the higher the blackness, the stronger the infrared radiation ability of the material. For example, the blackness of plastic is usually 0.8-0.95, while the blackness of metal is usually lower than 0.5. In addition, the blackness of the same material is also related to the roughness of its surface. For materials with smooth surfaces, such as polished metal surfaces, the blackness can be as low as 0.01. After the materials with different blackness are heated, the temperature distribution graph can be presented under the detection of the infrared thermal imager (the temperature is not the real temperature of the material). The colors displayed under the imager are also different. When the blackness parameter on the infrared thermal imaging camera is adjusted, the temperature distribution pattern will change, that is, the color presented by the above-mentioned materials will also change.

The preset base layer is a plastic layer or a metal mixture layer, or other materials that can be made into a coating. In the embodiment of the present invention, a plastic layer or a metal mixture layer can be coated on the part of the product shell that needs to be marked with an anti-counterfeit mark as the base layer, or the product shell can be directly used as the base layer, as long as the base layer is compatible with the coating The patterns or characters on the base layer may have the same color and different blackness under visible light, and the patterns or characters are called anti-counterfeiting patterns. When coating the anti-counterfeiting pattern, the material used can be powdered plastic or metal mixture, or plastic or metal mixture in a molten state, or other materials in other states, as long as it can be firmly adhered to on the base layer.

The following takes the anti-counterfeiting of electronic products as an example to illustrate the production and inspection method of the infrared anti-counterfeiting mark: directly spray the letters "A, B, C" on the shell of the electronic product (such as a U disk), that is, the letters "A, B, C" "As an anti-counterfeiting pattern, and the color of the material used to spray the letters "A, B, C" is the same as the color of the U disk shell under visible light (assuming that the U disk shell is monochrome), so that people cannot see the anti-counterfeiting pattern with the naked eye , to achieve a concealed effect. At the same time, the blackness of the material used to spray the letters "A, B, C" is different from that of the U disk shell material, so that the anti-counterfeiting pattern can be identified under the detection of the infrared thermal imager. After working for a period of time, the temperature of the electronic product rises. At this time, it can be detected under the infrared thermal imager, and the temperature distribution graph of all materials with different blackness on the U disk can be obtained. Since one temperature corresponds to one color, the temperature on the U disk Each material with different blackness presents a different color, so that the "A, B, C" on the casing of the U disk can be clearly distinguished to achieve the purpose of anti-counterfeiting. The casing of electronic products is generally a common metal mixture, so anti-counterfeiting patterns can be directly sprayed on the casing of electronic products. Of course, it is also possible to coat a base layer on the housing of the electronic product first, and then spray the anti-counterfeit pattern, the method is the same as above, and will not be repeated here.

It should be noted that the difference between the blackness of the base layer material and the material used to coat the anti-counterfeiting pattern can be selected as small as possible, so that the anti-counterfeiting pattern can only be recognized under a high-precision infrared thermal imager to increase Concealment of anti-counterfeiting patterns. In addition, the material used for coating the anti-counterfeiting pattern can be a material of a single blackness, or a material of multiple blacknesses. Still taking the anti-counterfeiting pattern as the letters "A, B, C" as an example, the three letters can be uniformly coated with a material with a blackness, or the letter A can be coated with a material with a blackness of Y1, and the letter B can be coated with a material with a blackness of Y1. It is coated with a material with a blackness of Y2, and the letter C is coated with a material with a blackness of Y3. It is also possible to coat different parts of each letter with a material with a different blackness. Depending on the value of the degree parameter, different pattern effects can be presented. Similarly, the above-mentioned differences between Y1, Y2, and Y3 can also be chosen to be as small as possible, so as to enhance the concealment of the anti-counterfeiting pattern.

The manufacturing method of the infrared anti-counterfeiting mark provided by the embodiment of the present invention only needs the base layer material and the material used for coating the anti-counterfeiting pattern to have the same color and different blackness under visible light, and there is no special requirement for the material itself, so it is different from the prior art. Compared with the need to use special ink, the production cost is reduced; moreover, only the anti-counterfeiting pattern needs to be directly coated on the base layer, and the manufacturing process is relatively simple. The technical solution provided by the embodiments of the present invention can make the infrared anti-counterfeiting mark simpler and reduce the production cost.

As shown in Figure 2, the embodiment of the present invention also provides a product with the infrared anti-counterfeiting mark as shown in Figure 1, including:

The base layer 1 is used to carry anti-counterfeiting patterns;

An anti-counterfeiting pattern layer 2, coated on the base layer 1, is used to form an infrared anti-counterfeiting mark together with the base layer 1;

The base layer 1 and the anti-counterfeit pattern layer 2 have the same color under visible light, and the blackness of the base layer material is different from that of the anti-counterfeit pattern layer material.

In the embodiment of the present invention, the base layer material includes: common PC plastic, metal mixture, or other materials that can be made into a coating. That is, a layer of plastic layer or metal mixture layer can be coated on the part of the product shell that needs to be marked with an anti-counterfeiting mark as the base layer, or the product shell can be directly used as the base layer, as long as the base layer is compatible with the anti-counterfeiting layer coated on the base layer. The pattern can have the same color and different blackness under visible light. The anti-counterfeit pattern layer material includes: ordinary PC plastic, metal mixture, or other materials that can be firmly adhered to the base layer.

It should be noted that the difference between the blackness of the base layer material and the blackness of the anti-counterfeiting pattern layer material can be as small as possible, so that the anti-counterfeiting pattern needs to be recognized by a high-precision infrared thermal imager to increase the concealment of the anti-counterfeiting pattern . In addition, the material of the anti-counterfeiting pattern layer can be a material of a single blackness, or a material of multiple blacknesses, for example, there are three kinds of materials, and the blacknesses are Y1, Y2 and Y3 respectively. In this way, different pattern effects can be presented under different blackness parameter values of the infrared thermal imaging camera. Similarly, the above-mentioned differences between Y1, Y2, and Y3 can also be chosen to be as small as possible, so as to enhance the concealment of the anti-counterfeiting pattern.

The products with infrared anti-counterfeiting marks provided by the embodiments of the present invention only need the base layer material and the material used for coating the anti-counterfeiting pattern to have the same color and different blackness under visible light, and there is no special requirement for the materials themselves, so it is different from the existing Compared with the technology that needs to use special ink, the production cost is reduced; moreover, it only needs to directly coat the anti-counterfeiting pattern on the base layer, and the manufacturing process is relatively simple.

The technical scheme provided by the invention can be applied in the technical field of anti-counterfeiting of electronic products.
