what is Fluorescent ink？

  Fluorescent ink is one of the more widely used inks in ticket printing, and its main component is fluorescent pigment. Fluorescent pigments are functional luminescent pigments. The difference from ordinary pigments is that when external light (including ultraviolet light) is irradiated, it can absorb a certain form of energy, and excite photons to release the absorbed energy in low visible form, thus producing different Fluorescence of the hue. The combination of different color lights forms an unusually bright color, and when the light stops emitting, the luminescence phenomenon disappears, so it is called a fluorescent pigment. The fluorescent pigment is mixed with the polymer resin binder, the solvent and the auxiliary agent, and the fluorescent ink can be obtained by grinding.
