Abstract
A method for texturing a plastic substrate, while forming a dye sublimation image in the plastic substrate is provided. A first side of a dye carrier sheet having an image formed thereon of a dye sublimation ink is placed on a second side of the plastic substrate to form a stack. A first side of a textured cover is placed on a side of the stack. A clamping pressure is provided on the textured cover and the stack, wherein the stack and textured cover are clamped together. The stack is heated to at least a sublimation temperature of the stack, which causes the dye sublimation ink to sublimate and penetrate through the second side of the plastic substrate, creating a dye sublimation image in the plastic substrate and wherein texture from the textured cover is transferred to a side of the plastic substrate.
