Abstract
Disclosed is a transfer printing method including the steps of: with use of a thermal transfer ink sheet wherein a heat-meltable ink Y containing a sublimation dye for yellow, a heat-meltable ink sublimation M containing a dye for magenta and a heat-meltable ink C containing a sublimation dye for cyan are applied on a single foundation or separate foundations respectively, selectively melt-transferring at least two of the sublimation inks Y, M and C onto a master sheet to form a master image in which at least two of respective images of the sublimation inks Y, M and C are superimposed one on the other; and transferring the sublimation dyes contained in the superimposed images onto an image receptor, wherein the sublimation inks Y, M and C are transferred onto the master sheet in the order of ink C, ink M and ink Y with an optional skipping-over of untransferred sublimation ink to the succeeding one. With this method a color dyed image can be obtained with a good color reproducibility, especially for an achromatic color.
