PRINTING PROCESS FOR A THERMAL TRANSFER TYPE MULTICOLOR PRINTER

A printing process for a thermal transfer type multicolor printer repeatedly transfer a plurality of color ink, such as yellow, magenta and cyan color ink, in turn on a printing paper so as to obtain a multicolor printed paper. After every time when one color ink is transferred to the printing paper, the printing paper lapped with a multicolor ink film is fed forward to a predetermined separation position at a predetermined printing speed under a pressure applied between a thermal head and a platen roller. Thereafter, the thermal head is separated from the platen roller so as to prevent the remaining heat of the thermal head from affecting to the multicolor ink film, so that the ink wax of the multicolor ink film is prevented from being melted and working as an adhesive agent for the printing paper and the multicolor ink film. Hence, the printing paper can be separated from the multicolor ink film with ease. Then the feeding speed of the printing paper is made slower than that of the multicolor ink film so as to prevent the multicolor ink film from slackening. Thereafter, the printing paper is completely separated from the multicolor ink film and the transferred ink quantity is not changed in this separation process, thus, the multicolor dot printing can be performed with accuracy. 16
