Brief metallic ink metallic inks, refers to a small sheet metal instead of traditional ink pigment or dye preparation, has a unique shiny metallic ink effect. Often said that mainly refers to silver metallic ink ink and gold ink. Silver ink pigment preparation made from aluminum; gold ink pigments are generally made of copper and zinc pigments formulated together in different proportions, by controlling and changing their ratio can produce green gold, green and red gold, red gold ink or the Pantone metallic inks needed. Classification plastic screen printing inks and ink prerequisites have evaporation drying inks, UV-curable inks, oxidative drying ink. ① volatile dry ink: screen printing is one of the most used ink. The main components of the ink film is a polymer material, solvent evaporation after printing, the polymer material to form an ink film. This evaporation drying process is reversible, i.e., the ink film drying solvent may be used redissolved. After the ink is transferred to the substrate, the ink film will have an ink solvent, evaporation of the solvent occurs first. Solvent in the ink by the action of the vapor pressure of diffusion in the atmosphere, forming a liquid film on the surface of the ink film, and then volatilized by the liquid film. In this drying process of the ink, general internal slower drying, sometimes need to be accelerated drying hair. Volatile ink, the ink is easy to use anodized wholesalers, general dry faster, so it is widely applied. ② UV curable ink (screen printing inks): UV inks can produce photochemical reactions, in a very short period of a few seconds, you can fully cured in plastic printing with more and more. The main component of the ink is photopolymerizable resin, initiator, pigment and additives, will in principle with an organic solvent. ③ oxidative drying inks: Ink containing low molecular weight polymer plating ink wholesalers, oxidation in the air, by heat, light or chemical reactions of reactive species to form a polymer film. This ink after printing to the substrate surface, generally require heating to promote hardening.
