Abstract
The present invention provides an ink set for which metamerism (the phenomenon in which the colors of a printed article (color recorded image) differ according to the light source used when viewing the printed article) is reduced. The ink set of the present invention comprises a yellow ink, a magenta ink and a cyan ink, wherein, when color mixing is carried out through ink jet output of the inks in the ink set such that the output color under a D50 light source is such that the spatial coordinates (L*,a*,b*) stipulated by the CIE are (50,0,0), the difference between the maximum value and the minimum value of the reflectance of the output color over a light source wavelength range of 400 to 700 nm is not more than 20%.
