Water-based inks are environmentally friendly inks that the printing industry can accept and are willing to accept. In addition to a very small amount of additives, water-based inks rarely contain organic solvents, so water-based inks also have no VOC emissions. However, if you want to use flexo-based water-based inks instead of flexo-printing UV inks on high-end labels , especially film stickers, there are many doubts in the industry. Therefore, flexographic water-based inks are environmentally-friendly inks that have unparalleled advantages in both cost and environmental friendliness. In order to be able to replace flexo-printed UV inks, their print performance must meet the following 9 market requirements.
1, stable pH
2, a reasonable viscosity
3, properly increase the color concentration of water-based ink
4, according to the characteristics of the printing plate to adjust the surface tension of the ink
5, the adhesion of the film and other non-absorbent printing materials
6, pay attention to the drying speed of water-based ink
7, pay attention to the surface tension of the ink film after drying
8, water-based ink cleaning loss
9. Prevention of ghosting failures
