When There's No Cure

Checking your UV

curing system

When you're faced with ink curing problems, how can you make sure that your UV curing system is working properly before you contact your ink supplier? There are several methods, including off-line tests, UV intensity tapes, various types of radiometers, and what may be the latest approach, spectroradiometers. These different approaches run the gamut from being "subjective at best, to providing concrete spectral data to verify optimum UV output," says Hahn.
