  • Ink jet printers are known and provide a number of advantages in the printing process. For example, ink jet printers are capable of providing relatively high-density color output at an acceptable printing speed. Furthermore, such printers are relatively inexpensive. As a result, it is desirable to utilize such printers in the formation of identification cards .
  • Identification card substrates generally have polyvinyl chloride (PVC) or polyvinyl chloride/polyvinyl acetate (PVC/PVCAc) surfaces.
  • DDTT Dye Diffusion Thermal Transfer
  • a protective material should be applied over the printed card surface to protect the printed image.
  • overlays can be applied to the printed card surface. Thin film overlays can be used to provide edge-to-edge protection to a printed surface. Unfortunately, such thin overlays only provide limited protection to the printed card surface.
  • patch laminates can be applied to printed card surfaces to provide additional protection to DDTT images.
  • Patches generally made of a polyester (PET) film and a thermal adhesive provide a bond between the polyester film and the card surface.
  • PET polyester
  • patch laminates exhibit resilient protection for a printed card surface
  • patch laminates do not generally provide edge-to-edge protection to the printed card surface since they are formed slightly smaller than the card.
  • card substrates can become warped along the outer edges of the identification card.
