Oh Say Can UV?

Factors to Consider

There are a number of special considerations involved in the decision to go UV. Good communication between the prepress department and the pressroom is essential. Screening curves must be adjusted to account for the additional dot gain that occurs with UV inks, and jobs also must be proofed on the actual substrates on which they will be printed. In addition, UV presses typically operate within much tighter tolerances with respect to ink-water balance and exposure to UV radiation. Press blankets can become embossed. Roller settings must be precise.
