ABSTRACT:
Methods and apparatus for processing printed substrates having a phase change ink layer of non-uniform thickness are disclosed. Application of a combination of heat and pressure reorients the printed ink layer to provide a layer having a substantially uniform thickness and flat surface conformation, at least in the area of each discrete color. A release surface (55) is positioned adjacent the printed ink layer during processing. A resilient contact surface (56) is also provided to facilitate reorientation of the printed ink layer. Mechanical buffing of the processed, printed substrate improves image quality. Application of a light transmissive, protective coating that overlays the printed ink layer also improves image quality.
