を特徴とするマルチ印字装置。[Claims for Utility Model Registration] In a multi-printing device that selectively generates heat from each heating element of a thermal head to sublimate dye from a dye transfer layer of an ink sheet and transfer it to the receiving layer side of image receiving paper, the thermal head comprises: A preheating pulse supply section that applies a preheating pulse to each heating element is provided, and the preheating pulse supply section outputs the preheating pulse to make the temperature of the ink sheet lower than the printing temperature and higher than the sublimation temperature by a predetermined temperature. After diffusing the dye from the dye supply layer of the ink sheet to the dye transfer layer side to increase the dye concentration on the dye transfer layer side,
A multi-printing device characterized in that printing pulses are selectively supplied to each heating element of the thermal head to transfer dye from the dye transfer layer of the ink sheet to the receiving layer of the image receiving paper.
