[0002] Water-based ink, flexographic water-based ink is also called liquid ink, which is mainly made of water-soluble resin, organic pigment, solvent and related additives through composite grinding. Water-based ink is particularly suitable for packaging and printing products with strict hygiene requirements such as tobacco, alcohol, food, beverage, medicine, children's toys, etc. Water-based ink is a uniform paste composed of binders, pigments, additives and other substances. The binder provides the necessary transfer properties for the ink, and the pigment gives the ink color. The binder of water-based ink is mainly divided into two types: water-dilutable type and water-dispersible type. There are many types of resins that can be used in the former, and the water-dispersible type of binder is obtained by emulsifying monomers in water.
