Fluorescent ink mainly of fluorescent pigment (dye), it is a functional luminous pigment, and the difference between general paint when external light (uv) radiation, can absorb a certain form, is not converted into heat energy, but stimulate photon, will absorb the energy released in the form of visible light, produce different fluorescence phenomenon in hue. Different color and light combine to form an unusually bright color, and when
