Abstract
The invention describes the unique finding that UV-curable flexo (and single pass inkjet) ink compositions can be more effectively cured by curing the pigmented ink compositions through two or more exposures to UV rather than a single exposure, where the total UV dose supplied by the multi-exposure approach is the same or less than the dose supplied by the single exposure.
