Embodiment 1
[0035] Such as figure 1 As shown, an anti-counterfeiting label is composed of four layers, including a substrate 1, an infrared ink anti-counterfeiting layer 2, an infrared ink coding layer 3 and a visible pattern layer 4 from bottom to top. The infrared ink anti-counterfeiting layer 2 , the infrared ink coding layer 3 and the visible pattern layer 4 are all arranged on the substrate 1 by printing. The substrate 1 shown can be a paper surface, a plastic surface, a cloth surface, or the like. Two-dimensional code patterns arranged in a predetermined manner are formed on the infrared ink coding layer 3 . The two-dimensional code pattern is printed with carbon-containing black ink or carbon-containing colorless ink. The ink used in the infrared ink anti-counterfeiting layer 2 is carbon-containing black ink or carbon-containing colorless ink.
[0036] Wherein, under the irradiation of infrared light, the spectral attenuation characteristics of the infrared ink coding layer 3 ar...
Embodiment 2
[0050] Such as Figure 4 As shown, the difference between the present embodiment and the first embodiment lies in the structure of the anti-counterfeiting label. Specifically, the anti-counterfeit label of this embodiment has a three-layer structure, which is a substrate 1, an infrared ink coded anti-counterfeit composite layer 2' and a visible pattern layer 3' from bottom to top. The infrared ink coding anti-counterfeiting composite layer 2' includes an infrared ink coding layer and an infrared ink anti-counterfeiting layer, that is, the infrared ink coding layer and the infrared ink anti-counterfeiting layer are located on the same layer. The implementation method is that before printing, the ink of the infrared ink coding layer and the ink of the infrared ink anti-counterfeiting layer can be blended together, and then printed on the substrate in the form of a two-dimensional code pattern. This can save one layer of printing and simplify the process of making anti-counterfe...
Embodiment 3
[0053] Such as Figure 5 As shown, the difference between this embodiment and the first embodiment lies in the structure of the infrared light source. Specifically, the infrared light source in this embodiment is an infrared LED 5 ′, that is, the same infrared LED is used as the illumination source. Certainly, a plurality of infrared LEDs having the same wavelength as the infrared light of the infrared LED 5 ′ can also be added to be used as auxiliary light sources when the light intensity is insufficient.
[0054] The anti-counterfeit label of this embodiment may be the same as that of Embodiment 1 or Embodiment 2, and the identification method of the anti-counterfeit label of this embodiment is the same as that of Embodiment 1.
