In addition, other anti-counterfeiting technologies are added to general anti-counterfeit inks to achieve multiple anti-counterfeiting functions. For example, a laser holographic logo combined with a fluorescent encryption security ink. Its anti-counterfeiting features, such as laser hologram identification combined with fluorescence encryption anti-counterfeiting ink, add new anti-counterfeiting measures to perform secondary encryption without increasing the integrity of the laser holographic identity, thereby improving its anti-counterfeiting function. Currently, a secondary encryption comprehensive anti-counterfeiting technology for laser hologram identification has been adopted on the market, ie, a special fluorescent material that can be detected through a certain process after being added to the laser hologram logo, is invisible to the naked eye under sunlight, and displays special features in the detection of special instruments. Colored fluorescent graphic. The technology has the characteristics of friction resistance, heat resistance, convenient and accurate detection, and strong anti-counterfeiting, and the production cost is less increased.
