PRESS DRYING/CURING--The ABCs of Press Drying

IR, on the other hand, is used to accelerate the drying of conventional inks and mainly works by increasing the pile temperature to help the inks to set quicker in the stack. This technique does not normally reduce the levels of spray powder needed to prevent set-off. WIR systems are similar to IR, but are used to dry water-based coatings over conventional inks.
