[Zhongbo.com] Glass screen printing machine has low requirements on ink. Glass screen printing machine can be applied to various types of inks, such as water-based ink, oil-based ink, synthetic gum ink, powder ink, etc. Therefore, the pigments in the ink and other solid materials have uneven particle sizes.
1. When the particles of the ink solids are large, the sealing phenomenon is likely to occur.
2. The mesh size and the area of ​​the through-holes selected are relatively small compared with the particle size of the ink, so that the ink of the coarser particles is not easily passed through the mesh and the phenomenon of sealing the net is also one of the effects. For the sealing plate caused by the large particles of the ink, it can be solved by selecting a good quality, small particle size and fine ink. The ink dries too fast during the printing process, which is also a phenomenon that causes the glass screen printing machine to seal. To print graphics on the glass surface, the outstanding feature is to dry quickly. Therefore, when the graphic is scraped, the volatile drying ink is used. In the normal printing production process, in order not to seal the ink, an appropriate solvent must be selected at the time of printing to control the drying speed. When printing glass products, the choice of ink must also take into account the effects of climatic conditions. In general, a late-drying agent is added to the ink during the summer ink, and if other types of ink are to be replaced if a sealer is used. If it is winter, you need to add dry ink to the ink. We also pay attention to the characteristics of the glass itself when printing glass products. So choose the right ink when choosing the ink.
