I don’t think we can compare screen printing drying characteristics to Digital printing inks.
Screen inks are much denser, heavier and thicker when they are screened on to a substrate. Solvent levels would be different as would drying times as a result.
Screen inks go on to a surface 10 to 15 times thicker than a digital inkjet image.
The solvent content and nature of both ink is different too. It would figure then that its drying reaction would also be different.
Heat may very well assist the drying of screen inks simply because they are so thick when laid onto a surface. The thickness of a digital ink layer would be minimal by comparison, however the components that make up the inks are very different.
