Abstract
Techniques are described for reducing or eliminating a bow in a plastic card that results from applying radiation, such as UV radiation, to a surface of the plastic card to cure radiation curable material that has been applied to the surface. In one embodiment, after printing of all radiation curable material on the plastic card is completed, radiation is applied to both surfaces of the plastic card. After applying the radiation, the plastic card complies with ISO 7810:2019, Clause 8.10.
