Uv ink and weak solvent ink determine their application methods and fields because of their inherent characteristics. UV ink can be used together with white ink, so many UV flat-panel printer manufacturers can print some beautiful relief effects. This is to pile up white ink with relief effect, and then print it again with color UV ink to achieve relief effect. The weak solvent cannot be mixed with white ink, so there is no way to print the relief effect.
In addition, because many materials of ink in the weak solvent class need coating treatment when printing, printing products without coating treatment are easy to fade; Uv ink can be directly used to print many materials without any coating treatment, which is simple, convenient and practical.
