ABSTRACT:
It is an object of the present invention to provide an ink set which makes it possible to obtain recorded images that have a broad color reproduction range and a high saturation, as well as glossiness without conspicuous graininess caused by dot expression, and which in particular makes it possible to achieve an extreme suppression of graininess caused by dot expression in cases where the ink set is used on media that have a coating layer, and to obtain recorded images with extremely superior coloring characteristics in cases where the ink set is used on ordinary paper. The present invention provides an ink set comprising at least a yellow ink (Y), magenta ink (M), cyan ink (C) and red ink (R), wherein the L* values in the CIE-stipulated Lab display system of aqueous solutions of the respective inks diluted 1000 times by weight are in the following ranges: (Y): at least 89 but no more than 94, (M): at least 76 but no more than 93, (C): at least 74 and no more than 87, (R): at least 55 and no more than 74.
