Abstract
The invention provides a pigment set comprising a magenta pigment, a yellow pigment, and a cyan pigment wherein the normalized spectral transmission density distribution curve of the cyan pigment has a density between 0.66 and 0.94 at 600 nm and a density between 0.83 and 1.0 at 610 nm, and the magenta pigment has a density between 0.25 and 0.93 at 520 nm, a density between 0.9 and 1.0 at 540 nm, and a density between 0.9 and 1.0 at 560 nm. Such a pigment set enables an increase in the color gamut available for imaging.
