With the rapid development of the printing machinery and automation, technological advances also makes printing ink industry has undergone a revolutionary change. People concerned about the gradual increase of ecological pollution, vegetable oil based inks and water-based inks and other eco-friendly inks increasingly popular. Offset printing ink occupy the largest market share, offset relative advantage over other printing processes have a beneficial effect on the offset printing inks. Digital printing inks are increasingly respected. 2017 digital printing ink market compound annual growth rate will reach 3.7%. Upgrade screen printing technology, computers and small companies in various universal application, internal graphics departments establish and quick print shops to stimulate the demand for digital printing inks. At the same time, digital printing and inkjet printing are likely to allow the expansion of the field of rapid development of digital printing inks. Technological innovation in the development of environmentally friendly inks, UV inks and inkjet inks and other new products to promote the growth of the global market for printing inks, radiation curable inks and energy-saving technology also provides a huge market opportunity. Gravure inks, screen printing inks, letterpress printing inks and other special inks equally rapid growth, which work together to promote the prosperity of the printing ink industry market prospects. 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 surface UV ink ink ink film wholesalers will solvents, solvent evaporation 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, generally interior slower drying, sometimes need to be accelerated drying hair. Volatile ink, easy to use, fast drying general, 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 inks, metallic inks can be completely cured wholesaler, used in plastic printing 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 polymers, oxidized 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.
