Anti-counterfeiting technology

With the continuous development of science and technology, the types of anti-counterfeit technologies are also increasing. It is mainly used in the trademark and packaging industry of goods, mainly in the following categories:

1. Temperature change Anti-counterfeiting technology is divided into reversible and irreversible. Its ink is colorless and can be printed alone or mixed with ordinary color inks. Security marks can be assigned to any position, and the colors are red, green, and black. The use of this technology includes the Beijing Red Star brand Erguotou wine, lighthouse brand paint and so on. Reversible 101 hair regenerative and so on. The identification method of this technology is simple. Lighters, matches, and cigarette butts can be used to generate a one-time color reaction in dark marks. After reversible heating, the color fades automatically, and when it is slightly cold, it returns to its original state.

2. Fluorescent and Phosphorescent Anti-counterfeiting Technology Currently, in Hong Kong Dollars, German Marks, 1990 editions of 50 yuan and 100 yuan, sun god oral liquid, Yan Sheng Bao Bao Ye, and crystal glasses and jewellery that participate in fidelity sales malls and jewelers This method is used for both Chinese and domestic wines. Commodity uses fluorescence anti-counterfeiting technology or phosphor anti-counterfeiting technology. It can be tested with desktop or portable 2-8 watts, wavelength at 3650 angstroms, and short-wave ultraviolet lamp (counterfeit banknote verifier) ​​during identification, showing obvious phosphorescence and fluorescence effects, concealment Strong.

3, metal stealth anti-counterfeiting technology It applies to metal or hard packaging. Its principle is to reflect the specified mark in accordance with the sun's rays or a parallel beam. The products currently using this technology include top ten sportswear, special vehicle licenses, etc. This technology has obtained national invention patents and is a unique new anti-counterfeiting technology with great potential for development.

4, laser holographic anti-counterfeiting technology It applies to a variety of goods on the label, even for credit cards, passports. It has the characteristics of exquisite appearance and strong decoration. It does not need to use tools when it is identified. Just look for an angle in a bright place to present one-dimensional, two-dimensional plus three-dimensional and three-dimensional graphics and rainbow effects.

5. New anti-counterfeiting technologies, such as biological and plant genes and codetypes, will also be available soon.
