Abstract
A process including: blending toners from a set of primary toners to form a set of secondary toners; and developing the secondary color toners to form spot color images, wherein the color gamut of all said images embody substantially the entire PANTONE.RTM. spot color space.
Claims19
A process comprising:
- modeling a target spot color with a set of primary toners;
- blending toners selected from the set of primary toners that match the target spot color to form a set of secondary toners;
- and
- developing said secondary color toners to form spot color images, wherein the color gamut of all said images embody substantially the entire spot color space used in printing, wherein the set of primary toners comprises 9 toners prepared from a set of 8 pigments consisting of:
- a yellow pigment, an orange pigment, a magenta pigment, a purple pigment, a blue pigment, a cyan pigment, a green pigment, and a black pigment;
- and a thermoplastic resin, and a pigment free colorless toner.
3 more elements
A process comprising:
- modeling a target spot color with a set of dry primary toners;
- blending the modeled dry toners to form a blended colored toner;
- and
- developing said blended colored toner to form spot color images, wherein the color gamut of all said spot color images encompasses from about 91 to about 100 percent of the spot color space.
1 more element
Colored toner compositions comprising:
- a modeled blend of first colored toners each comprised of a resin in an amount of from about 60 to about 99 weight percent of the total weight of the toner;
- a pigment in an amount of from about 1 to about 40 weight percent of the total weight of the toner selected from 8 pigments consisting of:
- a yellow pigment, an orange pigment, a magenta pigment, a purple pigment, a blue pigment, a cyan pigment, a green pigment, and a black pigment, and a pigment free colorless toner;
- and
- optionally a charge control agent or flow aid in an amount of about 0.5 to about 5.0 weight percent of the total, wherein the color characteristics of the color images embody substantially all the entire spot color space used in printing, wherein the pigments are selected from the group consisting of Pigment Yellow 17, Pigment Orange 34, Pigment Red 81:2, Pigment Violet 1, Pigment Violet 23, Pigment Blue 61, Pigment Blue 15:3, Pigment Green 7, and carbon black.
2 more elements
An imaging process comprising:
- developing electrostatographic latent images with modeled blended toners comprised of from 2 to about 9 primary colored toners and a pigment free colorless toner, and
- thereafter transferring and fixing the developed color images to a receiver member, and wherein the color characteristics of the resulting developed color images encompass from about 91 to about 100 percent of the PANTONE.RTM. color space.
A printing machine comprising:
- a developer housing and a latent image receiving member adapted for developing modeled mixtures of a set of primary toners to form spot color images, and wherein the color gamut of the spot color images encompasses substantially the entire spot color space used in printing.
