THERMAL TRANSFER RIBBON, PROCESS FOR MANUFACTURING A RIBBON, AND SYSTEM HAVING A THERMAL TRANSFER RIBBON AND A PRINTER

摘要

thermal transfer dye ink sheet and printer. The present invention relates to a thermal transfer dye sheet comprising a substrate having a region of a thermally transferable dye ink, the region including a first printable portion within the region, with a first optical density, a second printable portion within of the region, with a second optical density, the difference in optical density between the first and second optical densities being detectable by a detection means on a dye ink sheet printer, and a third printable portion within the region with a substantially optical density. The same as the first printable portion is provided, plus a method of manufacturing dye ink sheet and an associated printer.
