Temperature change security label production temperature change security label production people began to study the color coating, mainly used for thermal paper and cooking indicator. The late 1950s, a special anti-counterfeit labels, some of the sensitive material was found, with Shan ink manufacturing techniques to form a new type of heat-sensitive inks, and has been widely used in the printing field. Thermochromic ink is a new color ink, code labels, with changes in ambient temperature can rapidly change color, so that the color effect is a colored object dynamic, security labels, and town to play a certain security features ??? Thermochromic ink as a security temperature change security label printing oil quickly rapid development and application. Thermochromic ink, means at ambient temperature variations member changes color inks. The former class of thermochromic inks different color desired temperature can be divided into hand warm color security inks, temperature in the high temperature color security printing ink temperature is generally irreversible security label to a higher color press, it can be classified into Inverter reversible color, multi-color reversible) thermal security ink and irreversible (single and multi-color color irreversible irreversible thermal security of oil briefly describes several thermochromatic ink below. surface heat so the history can not be stacked color set irreversible labeling hot There was color-sensitive color inks, color two color-change ink after the non-inversion colorless appearance, color rendering is subjected to heat, fluorescent anti-counterfeit labels, color no longer recover after cooling colorless;. discoloration irreversible original color after the ink is heated by a colors into another color, color no longer restore its original color after cooling standard technical requirements for security labels security labels: identity unique, stable, rhythm, security efforts, the use of adaptive recognition performance, environmental requirements, technical security and confidentiality requirements of the eight general anti-counterfeiting technology. ID with the security role. security features and anti-counterfeiting label recognition method is the soul of security labels, security for those who aim to deceive and without the permission of the owner or imitation measures to prevent replication of activities undertaken security label |.
