A method for thermal transfer printing by heating a transfer sheet having a printing ink layer formed on a base sheet with a hot roll, wherein the base sheet comprises biaxially stretched plastic film, and, at the same time, pressing with the hot roll the transfer sheet against a substrate for printing, thereby transferring the printing ink layer to the substrate, wherein the substrate for printing is preheated prior to the pressing, and a transfer printing machine having a supplying roll axle for a roll of transfer paper urged to rotate in the rewinding direction by an urging force, a heat roll for performing heat transfer by pressing one surface of the transfer paper on which printing ink is not applied so as to cause the transfer paper to pressingly contact an object of transfer with a surface to which printing ink has been applied, and a takeup roll axle adapted for intermittently rotating and rewinding, for each rotation thereof, one pitch of the transfer paper having undergone the transfer, an improvement which comprises a pullback mechanism for partially pulling back, by utilizing the urging force, each pitch of transfer paper having been fed in one period of the transfer cycle before the next transfer cycle is started, are disclosed.
