The stronger the solvent's ability to dissolve the ink, the better the ink is dissolved, and the gloss of the ink layer is relatively good. Working ink viscosity is suitable. Conducive to the leveling of the ink, the gloss of the ink film is better. Ink deterioration. Solvent imbalance, excessive dilution, and solvent impact not only affect printing performance, but also damage the ink structure, causing the pigment to separate from the resin oil, often significantly reducing the gloss of the ink layer.
2, the link material
The binder not only acts as a dispersing pigment, but also acts as a protective pigment and gives a luster. Adding an appropriate amount of varnish to the range of color density allows the gloss of the ink layer to be improved to some extent.
3, the drying speed of the ink
In general, appropriately reducing the drying speed of the ink is advantageous for improving the gloss of the ink layer. The ink is dried too fast, the ink color after overprinting is easy to whiten, and the dull ink appears to be drying too slowly, and cracks and the like may occur, causing the ink layer to lose its luster.
4, squeegee
If the squeegee angle is too large or the squeegee is too sharp (such as a new blade), the printed ink layer will lack luster. Conversely, it is advantageous for the gloss of the ink layer to be improved.
5, printing environment
In the printing process, the solvent volatilizes quickly and the ink film dries quickly. Due to the effect of evaporation and heat dissipation, the heat around the ink film is absorbed, causing the water vapor in the air to condense rapidly, forming a mist on the surface of the printing ink film, and the ink layer is lost. Gloss, this effect will be more pronounced in high humidity environments.
