Abstract

It is an object of the present invention to provide an ink set which has a superior effect in suppressing gloss unevenness of printed images, and which thus makes it possible to obtain images that have a uniform gloss. The present invention achieves this object by providing an ink set comprising one or more color ink compositions containing a pigment as a coloring agent and a dispersing resin that is used to disperse this pigment, and one or more clear ink compositions which contain an aqueous polymer but which contain no coloring agent, wherein the dispersing resin and the aqueous polymer belong to a common category so that the 60° specular gloss (according to JIS Z 8741) of the printed images that are formed by the abovementioned color ink compositions and/or the abovementioned clear ink composition is substantially uniform.
