A color ink jet ink set for color printing; comprising

Color pigmented ink jet set

A color ink jet ink set for color printing is disclosed. The set comprises:

Color pigmented ink jet ink set

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.

Cyan and magenta pigment set

The invention provides an ink jet 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. Such a pigment set enables an increase in the color gamut obtainable for ink jet imaging.

Cyan ink jet pigment set

The invention provides a dye set comprising a magenta dye, a yellow dye, and a cyan dye wherein the normalized spectral transmission density distribution curve of the magenta dye 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 and the yellow dye has a density between 0.9 and 1.0 at 450 nm and a density between 0.8 and 1.0 at 470 nm. Such a dye set enables an increase in the color gamut obtainable for imaging.

Magenta and yellow dye set for imaging systems

The invention provides an ink jet pigment set comprising a magenta pigment, a yellow pigment, and a cyan pigment wherein the normalized spectral transmission density distribution curve of 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 obtainable for ink jet imaging.
