With the gradual establishment of the socialist market economy, the close integration of anti-counterfeiting technology and printing technology is of great significance in combating fake and shoddy products and regulating market order. The printing ink anti-counterfeiting technology has a very good development situation, and its application range has become increasingly widespread, and its benefits have also been getting better and better. Taking an anti-counterfeit ink with a wide range of applications as an example, it has been combined with many disciplines (such as optics, chemistry, electromagnetics, spectroscopy, etc.) to develop integrated ink anti-counterfeiting technology.
Anti-counterfeiting ink is a kind of special printing ink made by adding special anti-counterfeiting material to the ink's binder material. At present, the most widely used anti-counterfeiting inks are classified into seven major categories: (1) ultraviolet laser fluorescent inks; (2) sunlight-induced color-changing inks; (3) thermal security inks (thermochromic security inks or temperature-change security inks); (4) ) chemical reaction color ink, (5) intelligent machine read security ink; (6) multi-functional or integrated security ink (laser holographic plus fluorescent security ink); (7) other special ink (such as ovi light refraction security ink, etc.). These inks are characterized by the implementation of different external conditions (mainly using light, heat, spectral detection, etc.) to observe the color change of ink samples to achieve anti-counterfeiting purposes.
With the research made by China Mint Co., Ltd., Beijing Deli Technology Co., Ltd., Shanghai Longchen Industry Co., Ltd., Tianjin Jinda Chemicals Trade Development Co., Ltd., and Winning Guoan Anti-Counterfeiting Technology Co., Ltd. Can meet the needs of the domestic market. The domestic optical variable ink has the characteristics of dynamic color change and is difficult to reproduce. The anti-counterfeiting technology of light-variable ink was used for RMB 100 in 1999 in China. The anti-counterfeiting mark has never been copied by others in more than three years, and at the same time, the light Change ink is also widely used in various types of securities, trademarks, certificates, notes and product packaging printing anti-counterfeiting. However, imported anti-counterfeiting ink still occupies a considerable proportion. For example, train tickets printed by the Ministry of Railways have caused huge losses to the country due to fake tickets and altered tickets. It is said that they are equivalent to the two lines of the Beijing-Guangzhou line and Beijing-Harbin line. The total income of the section. Recently, the Ministry of Railways decided to change the number of new tickets, with a total of about 700 million printed tickets each year and 700 tons of paper, of which the ink is designed to use thermal inks from Mark Thermal Co., Ltd. Sensitive technology and ink are among the most advanced in the world, and are widely used in various anti-counterfeiting labels such as coinage, certificates, and cigarette packs. An important reason for relying on imports is that there is still a certain gap between domestic anti-counterfeit inks in terms of variety and quality compared with foreign advanced levels.
The development trend of anti-counterfeiting inks is: in terms of gravure inks, the goal is to increase production efficiency, reduce costs, enhance environmental protection, and improve the feel of gravure stamps; in the face of variable light inks, to enhance the effect of light changes and reduce talents. The goal is to improve the performance of thermal sensitive materials and sensitivity to discoloration in the area of ​​thermal inks; in the area of ​​ultraviolet laser fluorescence, the goal is to develop a system that is to develop testing instruments and related technologies in the development of ink elbow to improve Its machine-readable anti-counterfeit performance; In infrared ink, with the development of a unique infrared transparent, infrared absorption material as the goal. These are also the focus of security ink innovations.
