Generally speaking, oil-based and water-based inks are based on the dispersion medium of ink. In brief, oil-based inks disperse pigments in oil, such as mineral oil, vegetable oil, etc., and ink fixes pigments on the printing medium through oil penetration and evaporation; The water-based ink uses water as the dispersion medium, and the ink fixes the pigment on the printing medium through the penetration and evaporation of water.
Oil based ink and water-based ink have different dilution and cleaning media due to different dispersion media. Oil can only be diluted and cleaned with solvent, while water-based ink can be diluted and cleaned with water. We know that the decomposition and recovery of grease is troublesome,
So water-based ink is more environmentally friendly.
Both oil-based and water-based inks need to be dried or naturally dried to achieve a surface dry state.
On the outside, UV ink is similar to oily ink, but its use and curing process are completely different.
UV ink uses a different principle, that is, UV curing resin is used as dispersant, and UV light irradiation causes chemical reaction to cure the resin into a film. UV ink is attached to the printing medium by the adhesive force of resin, and can form a good film even if it is impermeable, so it can be printed on metal, glass, ceramics and other materials. UV ink has a short curing time and does not volatilize solvent substances, so it is also environmentally friendly and harmless ink. However, the decomposition and recovery of photo curing resin is also a big problem, so UV ink is not 100% environmentally friendly ink.
Since solvent ink is a dispersant or diluent of dye or pigment with solvent, the solvent used is usually highly volatile, so as to shorten the drying time of ink. The problem is that the solvent usually has a strong smell, which is sometimes harmful to human body and the environment. Therefore, solvent ink is not environmental friendly ink. When using it, pay attention to keeping the working environment ventilated and human body protected.
