How solvent based inks works during printing?
Solvent based ink print to substrate, solvent corrode the substrate, and meanwhile solvent volatilize, left pigment on substrate. As following pictures show.
What affects the outdoor durability life of solvent ink printing?
- Good pigment quality which warranty for outdoor durability.
- Good substrate quality, such as 3M material, warranty for outdoor durability.
- Ink dot size and density, design picture’s ink coverage (the more pigments on the surface of the substrate, the longer time it can keep the color) .
- The higher the content and quality of resin in the ink, the longer the weather resistance time. The resin provides adhesion and protection for the pigment.
- Cover the printed surface with a film will increase outdoor color resistance.
