MULTICOLOR THERMAL TRANSFER PRINTER

摘要

PROBLEM TO BE SOLVED: To prevent unevenness of printing from being generated in a series type multicolor thermal transfer printer.SOLUTION: A plurality of thermal transfer units respectively printing specified color ink image are arranged in series, and while a continuous transfer foil supply web 7 runs from a thermal transfer unit on the upstream side to a thermal transfer unit on the downstream side, by sandwiching it together with an ink ribbon 14 between the thermal head 13 and a platen 12 in each thermal transfer unit, images of respective color inks are overlapped and printed. By directly connecting rotational shafts of respective constant speed controlling servo motors 22 with the platens of all thermal transfer units, the rotation of the platens are controlled so that the continuous transfer foil supply web can run at the same constant speed in all the thermal transfer units.
