Disclosed herein is an ink-jet printing process comprising the three steps of (a) applying inks containing a disperse dye, a compound for dispersing the disperse dye and an aqueous medium to a cloth comprising fibers dyeable with disperse dyes according to an ink-jet system (b) subjecting the cloth, to which the inks have been applied, to a heat treatment and (c) cleaning the heat-treated cloth, wherein the inks comprise two or more inks which separately contain disperse dyes of the same hue and are different in dye concentration, and the thermal diffusivity of the disperse dye used in the ink having a low dye concentration is higher than that of the disperse dye used in the ink having a high dye concentration.
