Anti-counterfeiting ink preparation method

1. The use of mechanics (force-induced deformation, force-induced heat, force-induced vocalization, etc.)
Such as: force color change anti-counterfeit labels, the special function of the outer layer of micro-capsules, the inner layer of dye, mixed with ordinary ink, printing, testing only need to force the logo surface, due to external force, capsules The dye is released by the rupture, the color changes immediately, and the capsule dye color can be arbitrarily selected to obtain a variety of anti-counterfeiting effects.
2, using thermodynamic methods (thermochromic, thermochromic light)
Such as: In the ink to add thermochromic materials, if the ambient temperature changes, the color will change accordingly to achieve anti-counterfeiting effect.
3, the use of electrical methods (electrochromism, electroluminescence)
Such as: electrochromic ink, it is in the ordinary ink by adding some functional materials (such as tungsten trioxide, conductive polymers, etc.), when the DC voltage is applied to it, the structure of the functional material will change the appearance of the ink will change the color .
4, using optical methods (photochromism, photoluminescence, invisible discoloration, etc.)
Such as: fluorescent ink, it is added to the ordinary ink fluorescent material, when ultraviolet light, it will radiate visible light, to achieve anti-counterfeiting purposes.
5, according to customer needs, using a special anti-counterfeiting ink formula for the brand, with a unique strong, characterized anti-counterfeit ink products to protect the product's purpose.
