Abstract: When forming an image by superimposing heat-sublimation inks of yellow, magenta and cyan and a heat-sublimation ink of black on each other, an energy to be applied to the heat-generating elements in printing with the black ink is controlled such that the print paper is not deformed thermally. Carriage travel speed in printing with the black ink is made faster than that in printing with the inks of the three colors, thereby preventing the thermal deformation of the paper from occurring. A transparent heat-melt ink is printed over an image formed with the heat-sublimation inks of the three colors, thereby maintaining the resultant print in good quality.

Abstract: A thermosensitive color recording material is provided having cyan, magenta, and yellow thermosensitive coloring layers formed on a supporting material in this order. As a thermosensitive coloring layer is positioned deeper within the recording material, which corresponds to a lower heat sensitivity thereof, a larger heat energy for coloring is required.

In coloring the yellow thermosensitive coloring layer, it is necessary to prevent the underlying magenta thermosensitive coloring layer from developing color.
