What is the production method of anti-counterfeiting ink?

The graphic printed by offset printing is no different from ordinary ink under visible light, colorless and transparent under 850nm infrared radiation, and the graphic disappears. With the help of related infrared identification instruments, such as cameras, cameras, etc., its authenticity can be effectively detected. The offset printing anti-counterfeiting ink provided by the invention overcomes the defects of the prior art, the patterns printed by offset printing are not different from those printed by ordinary ink under natural visible light, and disappear under infrared radiation, so that the anti-counterfeiting effect is good, and the anti-counterfeiting ability of the tickets can be effectively improved when being used for high-end anti-counterfeiting tickets. In order to make the present invention more obvious and easy to understand, a preferred embodiment will be described in detail below.
