   Uv ink refers to the ink that is instantly cured by uv light irradiation. The main components of
 
uv ink include pigments, oligomers, monomers, photoinitiators and various additives. It uses
 
ultraviolet light of different wavelengths and energies to polymerize the monomers in the ink
 
binder into polymers, with bright colors, good printability, and suitable curing and drying speed.
 
The fluorescent ink is an ink made of fluorescent pigments, which has the property of
 
converting short-wave ultraviolet light into longer visible light and reflecting more dazzling colors.
 

   Fluorescent ink is divided into ultraviolet fluorescent ink, colorless fluorescent ink, invisible uv
 
ultraviolet fluorescent ink anti-counterfeiting: the material used is invisible fluorescent ink, and
 
the printing process is simple. It is not absolutely colorless or has absolutely no trace, so please
 
pay attention when using it. On pure white paper, even if completely transparent and colorless
 
varnish is printed, there will be a visual difference due to the difference in refraction and reflection
 
coefficient between paper and varnish, resulting in the difference between oil stains and paper
 
surface brightness. The ink prints invisible patterns or characters under the irradiation of
 
ultraviolet light. Shows a clear and bright fluorescent pattern. At present, most pharmaceutical
 
packaging adopts this kind of invisible fluorescent ink.
 

   Visible uv fluorescent ink anti-counterfeiting: the material used is tangible fluorescent ink,
 
the printing process is simple, the registration is accurate, and the printing effect is the same
 
as that of ordinary ink printing, but under the irradiation of ultraviolet light, the printed matter
 
shows abnormal light. At this time, It can be distinguished from ordinary ink.
