HIGH EFFICIENCY PRINTING METHOD FOR IMPROVED IMAGE QUALITY

摘要

Novel methods for calibrating a thermal printer by adjusting a look up table comprising the steps of receiving a test pattern to be printed on a receiver medium, printing the test pattern on the receiver medium, using a sensor to measure a depletion amount of donor material, and using a processor to adjust the lookup table based on the measured depletion amount are disclosed.

1. A method for calibrating a thermal printer by adjusting a lookup table, comprising:
providing a donor ribbon having donor material; providing a print head located in the thermal printer, wherein the print head is adapted to print images by causing donor material to transfer from the donor ribbon onto a receiver medium; receiving a test pattern to be printed on the receiver medium; printing the test pattern on the receiver medium by heating the print head to heat the donor ribbon causing the donor material to transfer from the donor ribbon onto the receiver medium, thereby depleting donor material on the donor ribbon; using a sensor to measure a depletion amount of the donor material on the donor ribbon after printing; and using a processor to adjust the lookup table based on the measured depletion amount of donor material, thereby calibrating the thermal printer.
