Abstract
A plastic card personalization system with a drop-on-demand plastic card print station that prints radiation curable material, a plasma treatment station, and a radiation curing station. By using a combination of controlling plasma treatment conditions on the surface of the plastic card prior to DOD printing together with controlling the dwell time of the printed material applied to the plastic card prior to full curing of the printed material, a surprising and unexpected improvement of the adhesion of the printed material to the plastic card is achieved.
