Printing ink anti-counterfeiting technology
1) fluorescent ink. Fluorescent ink is made of fluorescent materials dissolved in the corresponding resin and, its main composition is fluorescent pigments, when external light, can absorb a certain form, is not converted into heat energy, stimulate photon directly, the energy released in the form of low visible light, resulting in a different color fluorescent. With fluorescent ink printed colorful print, decoration effect is good, in under the action of visible and ultraviolet light, a sparkling fluorescence. Fluorescent ink anti-counterfeit packaging in its own best allocate the anti-counterfeiting effect, different formula can get different fluorescence effect, the general is hard to control.
(2) thermal anti-counterfeit printing ink. Can occur under the condition of heating, the effect of ink is called thermal anti-counterfeiting ink, according to the temperature needed for color is different, can be divided into his hands warm color ink and color ink in high temperature. Thermal is an essential part of the anti-counterfeiting ink color paint, because the paint color change with different before and after heating, this as a basis to determine whether a brand or product fake, discern not only convenient, and fast.
3. Light color ink. Excitation light ink color change is due to ultraviolet light and color, under the irradiation of the sunlight or ultraviolet light can be changed from colorless to blue, purple, yellow wait for color, also can from one color to another color. Its color principle is: when the sunlight or ultraviolet light irradiation to ink, ink are the photosensitive material, its molecular structure is changed, resulting in a color appearance. When moving to external stimuli, photosensitive material in the ink went back to the original ground state, ink and restore to the original color. This kind of ink in daily-use cosmetics has a very wide range of application of anti-counterfeiting packaging and printing.
