The screen printing process of GST centrifugal tube automatic screen printing machine equipment is that the ink passes through part of the mesh of the screen and then leaks on the substrate, and the rest of the mesh of the screen is blocked, and the ink cannot penetrate. The ink is poured on the screen during printing, and the ink will not leak through the mesh to the substrate without external force, but when the scraper scrapes the ink with a certain pressure and inclination angle, it will be transferred through the screen To the following substrates to achieve image replication.
Precautions when coloring screen printing ink:
1. Adopt the principle of "from light to dark", regardless of the preparation of light-colored or bright colored inks, when the hue is close to the sample, be careful. It is best not to mix inks produced by different manufacturers, try to use inks of different colors from the same manufacturer for color mixing, otherwise uneven color tone will occur, and in severe cases, cohesion will occur and the ink will be scrapped.
2. When mixing inks, try to add as few inks of different colors as possible. Generally speaking, the less types of colored inks are used, the better the mixing effect will be.
3. Some screen printing inks are dried by drying. Light colors are lighter than undried ones, and dark colors are darker after drying. In addition, whether the color tone of the ink is different before and after drying during printing is a problem that is easily overlooked. Generally speaking, through natural drying (solvent volatile ink), the substrate is plastic, metal, paper, glass, etc., and the color will not change; but if it is a color material for ceramics, the color will not appear until after burning and oxidation. , can only be adjusted by experience. However, for the screen printing inks that are dried by heat-setting and light-setting, the color changes in shades. When the amount of ink adjustment is large, the ink adjustment machine can be used to complete the color adjustment in a short time.
