When There's No Cure

Running UV inks

TAPP Technologies has been running UV inks for about nine years. Overall, Swartz thinks they are easier to run than conventional inks, since you don't have to mix fountain solutions. On the flip side, UV inks are extremely temperature sensitive, and transfer and lay down is more sensitive. Swartz keeps a close eye on process and ambient conditions, with temperature-controlled rollers and air conditioning on the press.
