Abstract: A receiver having an image side and a non-image side bent in a bend area including a bend axis. Toner is deposited on the image side of the receiver in the bend area using an electrophotographic print engine. The deposited toner is fused to the receiver. During or after fusing, the fused toner is heated to a selected fusing temperature greater than or equal to the Tg of the toner. A heat-shrinkable film is affixed to the heated toner after heating the toner, wherein the Tg of the film is greater than the Tg of the toner. The toner is cooled below its Tg after affixing the film. The bend area of the receiver is reheated after cooling the toner, so that the temperature of the heat-shrinkable film rises above its Tg, the heat-shrinkable film contracts, and the receiver bends at the bend axis.
