The ink of screen printing mesh is an important soul of printing. It is characterized by a relatively large degree, a relatively small viscosity, and moderate flow. The viscosity is generally between 3 and 12 Pa·s. In this case, the ink is more easily permeated through the mesh under pressure to form a print. The thickness of the ink film is between 8 and 30 μm. Screen ink has the characteristics of strong hiding power, good adhesion on the surface of the substrate, bright color and good gloss, but poor light resistance and abrasion resistance. In the printing process, the appropriate solvent can be selected to adjust the viscosity and fluidity of the ink. The oxidative polymerization drying type screen ink can be added with a desiccant in an appropriate amount to improve the drying property of the ink.

When the ink of the screen printing mesh needs to be selected, it must be considered from the aspects of viscosity, thixotropy, yield value, fluidity, plasticity, fineness and the like. It is necessary to buy the right one to print more effective.
