摘要:
A high efficiency thermal printing system, comprising: a donor ribbon having donor material; a receiver medium; a test pattern to be printed on the receiver medium using the donor ribbon; a print head, a sensor, and a processor is disclosed. The present invention is adapted to print the test pattern on the receiver medium by heating the donor ribbon to cause the donor material to transfer from the donor ribbon onto the receiver medium, thereby depleting donor material on the donor ribbon. Moreover, the sensor is adapted to measure a depletion amount of the donor material on the donor ribbon after printing the test pattern, and the processor is adapted to calibrate the thermal printing system by adjusting a lookup table in response to the measured depletion amount of donor material.

A thermal transfer sheet according to an embodiment of the present disclosure includes a substrate and a transfer layer disposed on one surface side of the substrate, in which the transfer layer includes at least a discoloration- or decolorization-imparting layer, and the discoloration- or decolorization-imparting layer contains a compound responsible for discoloration or decolorization.
摘要:
A thermal printer includes a single thermal recording medium interposed between printing paper and a thermal head so that when predetermined energy is applied to the thermal head, colorant on the thermal recording medium is transferred to the paper to print out a desired letter or symbol, or alternatively the printed letter or symbol is removed and erased from the paper because the colorant once transferred to the paper is attached to the colorant on the thermal recording medium. A printing method using the thermal printer is characterized in originally setting printing energy and erasing energy the latter of which is equal to or larger than the former, applying the printing energy to the thermal recording medium to effect printing operation, and applying the erasing energy to the thermal recording medium to attach it to the printed letter or symbol on the paper to remove and erase it from the paper.

摘要:
A thermal transfer recording and correction method, in which a thermal transfer ink layer is placed in contact with a transfer-receiving medium and is heated by heat generating elements of a thermal head in a pattern corresponding to a recording signal, is improved by preheating the ink layer. The ink layer, which is characterized by a transfer initiation temperature, is preheated by the thermal head which is heated by a preheating means. When a region of the ink layer is then further heated by the heat generating elements, the temperature of that region has a maximum and a minimum both within a range extending from the transfer initiation temperature to about 40.degree. C. higher than the transfer initiation temperature. Since the maximum and minimum temperatures are within a suppressed temperature range, an erroneous image can be more easily peeled off the transfer-receiving medium.

The negative image left on an ink donor sheet after thermal recording is erased by heating the remaining ink at a point downstream of the recording station and either removing the remaining ink or spreading the ink to obliterate the negative image.
