Water-based ink is referred to as Yanhuang ink. Flexographic water-based ink is also called liquid ink. It is mainly made of water-soluble resin, organic pigments, solvents and related additives through compound grinding. Water-based ink is especially suitable for packaging and printing products with strict hygienic conditions such as tobacco, wine, food, beverages, medicines, and children's toys.

Water-based ink

Solvent-based inks are divided into benzene and non-benzene, and benzene inks are being phased out. Various solvents used in solvent-based gravure inks can form toxic and harmful exhaust gases.

Solvent-based ink

The difference between the two is:

① Water-based ink uses inorganic solvent water as the main carrier and can be diluted with water; and Solvent-based ink is an ink that uses organic solvents as carriers and can be diluted/dissolved with various organic solvents.

② Water-based inks are mostly used for printing on various absorbent materials, such as: paper/textiles/non-woven fabrics, etc. Structural absorbent materials can also be printed with water-based inks, which does not necessarily refer to the material. Absorbent materials. Solvent inks are generally used on non-absorbent materials, such as metals/polymers, etc., and are also used on absorbent materials that require quick drying, such as paper, etc.?

③Water-based The ink is more environmentally friendly, has a light taste, and has poor adsorption power. It is mainly used for printing on non-woven fabrics and textiles. Solvent-based ink has a pungent smell and is mainly used for printing trademarks, books and periodicals, etc.
