Abstract
A color electrostatographic printer apparatus applies respective color separation toner images to a receiver member to form a color image. A fuser station fuses, or at least tacks, the color image to the receiver. A clear toner overcoat is then applied to the fused color toner image using an inverse mask, and enhanced glossing of the image is provided by a belt glosser to improve color gamut.

A method of forming a multi-color image on a receiver comprising:
- forming a multi-color toner image, on a receiver, with toners of at least three different colors of toner pigments which form various combinations of color at different pixel locations on the receiver to form the multi-color toner image thereon;
- forming a clear toner overcoat upon the multi-color toner image, the clear toner overcoat being deposited as an inverse mask;
- pre-fusing the multi-color toner image and clear toner overcoat to the receiver to at least tack the toners forming the multi-color toner image and the clear toner overcoat;
- and
- fusing the clear toner overcoat and the multi-color toner image using a belt fuser to fix the clear toner overcoat to the receiver and/or provide an improved gloss to the multi-color toner image.
A method of forming a multi-color image on a receiver comprising:
- forming a multi-color toner image, on a receiver, with toners of at least three different colors of toner pigments which form various combinations of color at different pixel locations on the receiver to form the multi-color toner image thereon;
- pre-fusing the multi-color toner image to the receiver to at least tack the toners forming the multi-color toner image;
- forming a clear toner overcoat upon the at least tacked multi-color toner image, the clear toner overcoat being deposited as an inverse mask;
- and
- fusing the clear toner overcoat and the multi-color toner image using a belt fuser to fix the clear toner overcoat to the receiver and provide an improved gloss to the multi-color toner image.
A system for printing color images comprising:
- a tandem color electrostatographic printer apparatus having three or more color printing stations for applying respective color separation toner images to a receiver member passing there through in a single pass to form a multi-color image;
- a fusing station for fusing the multi-color image;
- a clear toner overcoat printing station for applying a clear toner overcoat upon the multi-color toner image in the form of an inverse mask;
- and
- a belt glosser for providing enhanced gloss to the multi-color color image having the clear toner overcoat.
A system for forming a multi-color image on a receiver comprising:
- means for forming a multi-color image on the receiver with materials of at least three different colors, which form various combinations of color at different pixel locations on the receiver to form the multi-color image thereon;
- means for forming a clear overcoat upon the multi-color toner image, the clear overcoat being deposited as an inverse mask having a gentle roll off in the mid-tone region;
- and
- means for subjecting the multi-color toner image with the clear toner overcoat to heat and pressure in a belt glosser to provide an improved gloss to the multi-color toner image.
A method of forming a multi-color image on a receiver comprising:
- forming a multi-color image on the receiver with materials of at least three different colors, which form various combinations of color at different pixel locations on the receiver to form the multi-color image thereon;
- forming a clear overcoat upon the multi-color toner image, the clear overcoat being deposited as an inverse mask having a gentle roll off in the mid-tone region;
- and
- subjecting the multi-color toner image with the clear toner overcoat to heat and pressure in a belt glosser to provide an improved gloss to the multi-color toner image.
A method of forming a single color image on a receiver comprising:
- forming a color toner image on the receiver with a toner with toner pigment in the selected color;
- forming a clear toner overcoat upon the color toner image, the clear toner overcoat being deposited as an inverse mask;
- pre-fusing the color toner image and clear toner overcoat to the receiver to at least tack the toner image and the clear toner overcoat;
- and
- fusing the clear toner overcoat and the color toner image using a belt fuser to fix the clear toner overcoat to the receiver and/or provide an improved gloss to the toner image.
A method of forming a multi-color image on a receiver comprising:
- forming a multi-color image on the receiver with materials of at least three different colors, which form various combinations of colors at different pixel locations on the receiver to form the multi-color image thereon;
- forming a clear overcoat upon the multi-color toner image, the clear overcoat being deposited as an inverse mask having a gentle roll off in the mid-tone region;
- and
- subjecting the multi-color toner image with the clear toner overcoat to heat and pressure to fuse the multi-color toner image with the clear toner overcoat to the receiver to form a print wherein the print that is formed exhibits lower granularity than a similar multi-color image on a similar receiver and which is not subject to an overcoat of clear toner.
A method of forming a print having a multi-color image supported on a receiver comprising:
- forming a multi-color toner image on the receiver with toners of at least three different colors of toner pigments, which form various combinations of color at different pixel locations on the receiver to form the multi-color toner image thereon;
- forming a clear toner overcoat upon the multi-color toner image, the clear toner overcoat being deposited as an inverse mask;
- pre-fusing the multi-color toner image and clear toner overcoat to the receiver to at least tack the toners forming the multi-color toner image and the clear toner overcoat;
- and
- subjecting the clear toner overcoat and the multi-color toner image to heat and pressure using a belt fuser to provide an improved color gamut to the image.
