Description: Water-based ink is made of water-based resin, pigments, solvents and additives through compound processing and grinding. The water solubility mainly plays the role of the binder, so that the pigment particles are evenly dispersed, so that the ink has a certain fluidity and the adhesive force that occurs, so that the ink forms a uniform film after printing.
Matters needing attention before using water-based ink:
1. Water-based inks cannot be mixed with solvent-based inks, or use benzene and ester organic solvents in water-based inks.
2. Water-based inks should be stored indoors at a temperature of 5-40 degrees and avoid direct sunlight.
3. Because of the evaporation of water during the printing process, the viscosity will rise and the PH value will drop. The pH stabilizer should be between 8-9.5.
4. Because of the complexity and diversity of current printing substrates, strict pre-production tests are required before selecting a certain ink for mass production.
5. The ink will be gelatinous when stored for a long time, so it needs to be fully stirred during use.
6. After the ink is dispensed, you need to stand still and defoam before use, otherwise bubbles or pinholes will occur in the ink layer.
7. Static electricity on the screen or printed surface will cause pinholes in the printing ink layer.
8. When printing is stopped for a short time, it should be covered with a layer of ink, otherwise it is easy to cause network blocking.
9. Rinse with water immediately after printing, otherwise it is easy to block the net after being dry, and the thickness of the screen can be increased to reduce the oil blocking the net.
