Fluorescent ink made with fluorescent pigments that has the property of converting short wavelengths of ultraviolet light into longer visible light to reflect more dramatic colors.
Fluorescent ink is ultraviolet fluorescent ink, also known as colorless fluorescent ink and invisible ink, is made by adding the corresponding visible fluorescent compounds in the ink.
Application of ultraviolet light (200-400nm) irradiation excitation and emit visible light (400-800nm) special ink, known as UV fluorescent ink.
It can be divided into short wave and long wave according to different excitation wavelength.
The excitation wavelength of 254nm is called short-wave UV fluorescent ink, the excitation wavelength of 365nm is called long-wave UV fluorescent ink, according to the change of color and divided into colorless, colored, discoloration three, colorless can display red, yellow, green, blue and yellow colors;
Color can make the original color bright;
A change of colour may change one colour into another.
