Water-based inks are made from water-based resins, pigments, solvents and additives through compound processing and grinding. The water-soluble resin mainly acts as a binder in the ink, and the pigment particles are evenly dispersed, so that the ink has a certain fluidity, and the adhesion to the substrate material is generated, so that the ink forms a uniform film layer after printing.
Performance characteristics of water-based ink:
1. The water-based ink is a new type of environmentally friendly printing ink with good adhesion, good flexibility, good elasticity, anti-sticking, washing resistance, printability, and over-netting properties, and high solid content.
2. Non-flammable, stable ink, non-corrosive to printing substrate, prevent color migration, strong water resistance, and fast drying. Not only can it reduce the hidden dangers caused by static electricity and flammable solvents, but also reduce the residual toxicity on the printing surface, and it is very convenient to clean the printing equipment, so it is especially used in food, beverage, pharmaceutical and other packaging industries.
3. The water-based ink solvent is water and a small amount of alcohol, which significantly reduces VOC emissions, prevents air pollution, and does not affect human health. Products that come into direct contact with the human body, such as T-shirts and other pure cotton, elastic fabrics, The insole printing industry also has a wide range of uses, is a world-recognized environmentally friendly material, and is currently the ink recognized by the American Food Association among all printing inks.
4. In terms of cost, due to the current rising prices of organic solvents, the use cost of solvent-based inks is increasing day by day, and the solvent and water-screen printing of water-based inks mainly use tap water, and the use cost will undoubtedly be much lower than solvent-based inks.
