Prismatic retroreflective article bearing a graphic and method of making same
Abstract:
A prismatic retroreflective article bearing a graphic and a method of making the same. The prismatic retroreflective article can include an optical layer including a front surface and a rear structured surface defined at least partially by internally reflecting cube-corner optical elements. The rear structured surface can be infused with a graphic, such that the prismatic retroreflective article retroreflects the graphic when viewed from the front surface of the optical layer. The method can include providing a graphic donor sheet, coupling the graphic donor sheet to the prismatic retroreflective article to form a composite, and applying heat and pressure to the composite to transfer at least a portion of the sublimation colorant from the graphic donor sheet to the rear structured surface of the optical layer.
