Where are The Application Areas of UV Offset Printing Inks?
UV offset printing ink refers to the ink that is instantly cured by UV light irradiation. The main components of UV offset printing ink include pigments, oligomers, monomers (reactive diluents), photoinitiators and various auxiliaries. Among them, resins and reactive diluents play the role of fixing pigments and providing film-forming properties; pigments give ink moderate color and covering power to the substrate; photoinitiators are required to absorb photons to initiate polymerization under the interference of pigments.
