What Is UV Curing Ink Science & How Does It Work in Flatbed Printing?
UV curing ink science involves a photochemical process where photoinitiators in UV-curable inks (monomers, oligomers, pigments) absorb UV/LED light (365-405nm), triggering polymerization to instantly harden ink without drying or volume loss. This enables sharp, durable prints on heat-sensitive substrates like...
