SHEETFED DRYING/CURING SYSTEMS -- Running Hot and Cold

Whitehead sees the use of UV coatings, specifically, as a pivotal decision in the approach to drying/curing taken by a sheetfed printer. Sheets that are run with conventional inks need to dry or be sealed before a UV coating can be applied, which necessitates a separate pass for the coating, he points out. "Using a hybrid or full UV ink system provides the capability to UV coat in-line, while retaining the higher gloss levels and much greater rub resistance offered by the process."
