[0002] UV (ultraviolet light curing) ink refers to ink that uses ultraviolet light of different wavelengths and energies to polymerize monomers in the ink binder, causing the ink to form a film and dry. UV ink is also a type of ink. As inks, they must have vibrant colors (except in special cases), good printability, suitable curing and drying rates, good adhesion, and properties such as abrasion resistance, corrosion resistance, and weather resistance. However, due to factors such as manufacturing equipment and production processes, a certain amount of impurities may exist in the ink, which need to be filtered out.
