[0002] Ink is an important material for printing. It prints patterns and text on paper through printing and is an indispensable material in the printing industry. During the production process of printing ink, the raw materials usually need to be screened. During the grinding process of the raw materials of printing ink, although the pigments are dispersed, there is still a risk of re-aggregation. Screening can further improve the stability of the pigments and binders and prevent the ink from changing during use. Impurities in the raw materials of printing ink (such as large-particle pigments that have not been fully ground) may cause problems such as mesh clogging or plate clogging during the printing process. These impurities can be removed by filtration to ensure printing quality. The traditional production method requires manual screening of the raw materials of printing ink. The manual screening method is inefficient and cannot meet the needs of efficient production. Utility Model Content
