Abstract
An inkjet ink set includes eleven colored inks and a surface enhancing ink. The eleven colored inks include a magenta ink, a light magenta ink, a yellow ink, a cyan ink, a light cyan ink, a medium gray ink, a light gray ink, a photo black ink, a red ink, a green ink, and a blue ink. The surface enhancing ink is configured to enhance gloss of an image formed with at least one of the eleven colored inks.
Claims20
An inkjet ink set, comprising:
- eleven colored inks including a magenta ink, a light magenta ink, a yellow ink, a cyan ink, a light cyan ink, a medium gray ink, a light gray ink, a photo black ink, a red ink, a green ink including a PG 36 pigment, and a blue ink including a PV 23 pigment, each of the green and the blue ink including hexamethylenediamine tetra(methylene phosphonic acid);
- and
- a surface enhancing ink configured to enhance gloss of an image formed with at least one of the eleven colored inks.
An inkjet ink set, comprising:
- a magenta ink;
- a light magenta ink;
- a yellow ink;
- a cyan ink;
- a light cyan ink;
- a medium gray ink;
- a light gray ink;
- a photo black ink;
- a red ink;
- a green ink, including:
- an ink vehicle including:
- a hexamethylenediamine tetra(methylene phosphonic acid) first component;
- and
- a second component selected from at least one of water soluble polymers, non-ionic surfactants, glyceryl polyoxyethyl ether, 2-pyrrolidone, glycerol, diethylene glycol, 1,2-hexanediol, ethoxylated nonionic fluorosurfactants, biocides, triethanolamine, Tris[hydroxymethyl]aminomethane, and combinations thereof;
- and
- a PG 36 pigment;
- a blue ink, including:
- an ink vehicle including:
- a hexamethylenediamine tetra(methylene phosphonic acid) first component;
- and
- a second component selected from non-ionic surfactants, glyceryl polyoxyethyl ether, 2-pyrrolidone, diethylene glycol, 1,2-hexanediol, ethoxylated nonionic fluorosurfactants, biocides, triethanolamine, and combinations thereof;
- and
- a PV23 pigment;
- and
- a surface enhancing ink substantially free of colorants, and including:

A method for forming an image on a substrate, the method comprising:
- establishing at least one colored ink on at least a portion of a substrate;
- and
- establishing a surface enhancing ink on:
- 1) the at least a portion of the substrate;
- or 2) the at least a portion of the substrate and at least an other portion of the substrate where there is an absence of the at least one ink;
- wherein the at least one ink and the surface enhancing ink are part of an ink set including a magenta ink, a light magenta ink, a yellow ink, a cyan ink, a light cyan ink, a medium gray ink, a light gray ink, a photo black ink, a red ink, a green ink including a PG36 pigment, and a blue ink including a PV23 pigment;
- and the surface enhancing ink;
- and wherein each of the blue ink and the green ink includes hexamethylenediamine tetra(methylene phosphonic acid).
