Grinding color paste: mixing water-soluble resin, pigment, auxiliary agent, solvent (water), etc., stirring and dispersing by a high-speed disperser, and grinding into a standby color paste.

Formulating the ink: mixing and mixing the alternate color paste, auxiliary agent and solvent (water), and dispersing it by grinding to make it have sufficient fineness, luster and coloring power, and the filter package is an aqueous ink product.

In summary, we have selected various types and varieties of water-soluble acrylic resin, through the comparative test screening of pigments and additives, and compounding with acrylate emulsion, adding cross-linking agent, through orthogonal test preferred formula, The water-based ink products developed by the company have been tested and used by relevant units, which prove that their indicators have reached the advanced level of similar products at home and abroad, and have been well received by the users.
