Abstract:
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; using a sensor to measure an initial amount of donor material on the donor ribbon prior to depletion; 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 the sensor to measure a depletion amount of the donor material on the donor ribbon after printing; using a processor to calculate a difference between the initial amount of donor material and the depletion amount of donor material; and using the processor to adjust the lookup table based on the difference, thereby calibrating the thermal printer.
