Today Vility tell you what is the Matters needing attention in automatic screen printing machine ink toning.
1. When mixing ink, add as few inks of different colors as possible. The fewer types of color inks, the better the mixing effect.
2. Adopt the principle of "from light to dark", no matter formulating light-colored or bright colored ink, be careful when the hue is close to the sample. Ink produced by different manufacturers, it is best not to mix and call, and try to use ink of different colors from the same manufacturer for color matching, otherwise, uneven color tone will occur, and in severe cases, condensation will occur and the ink will be scrapped.
3. Screen printing inks are dried by drying. Light colors are lighter than undried ones after drying, 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 easy to ignore. 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 only develop after burning and oxidation. , can only be adjusted by experience. For screen printing inks dried by heat curing and light curing, the color changes in shades, as mentioned above. When the amount of ink adjustment is large, you can use the ink mixing machine, which can complete the color adjustment in a short time.
Hope above precautions are helpful for new printers.
