How does the oily ink used in screen printing make him odorless?
Luminous powder can be made by direct ink printing (by adding luminous powder in transparent ink), or by transfer printing;
Ink is an oil soluble polymer resin and filling material, toner mixture made, solvents have a certain odor, and now the market dilution of ink using toluene, ketones, solvents dissolved, have a smell;
This should start with the production of ink, with low flavor solvents instead of DBE, ethyl grease and other solvents!
