Abstract
An apparatus for texturing a plastic substrate, while forming a dye sublimation image in the plastic substrate, wherein the plastic substrate has a first side and a second side, is provided. A textured cover is on a side of a platen, wherein the platen is on a first, untextured side of the textured cover. A first side of the dye carrier is on a second, textured side of the textured cover, and wherein the plastic substrate is supported on a second side of the dye carrier, wherein a first side of the plastic substrate is supported by the dye carrier, wherein the textured side of the textured cover has a texture to be transferred to the plastic substrate. A membrane is on the second side of the plastic substrate. A vacuum pump provides a vacuum between the membrane and the platen. A heater is positioned to heat the plastic substrate.
