Abstract
A color image forming machine is provided having a plurality of xerographic marking engines, each forming associated color separations that are combined to produce a color print image. Each marking engine includes two independently controlled developers using toners of the same color and strength of color but with different fused gloss characteristics, in that one of the toners will produce a print with a comparatively lower gloss and the other will produce a print with a comparatively higher gloss, thereby providing a greater control over the range of the gloss of the output print.
Claims20
A color image forming machine including a plurality of marking engines generating associated color separations in a color toner image for producing a color print, each marking engine comprising:
- a photoreceptor drum,
- a first developer disposed adjacent the photoreceptor drum including a first toner having a predetermined first color and first color strength corresponding to the associated color separation, and first fused gloss characteristics, and
- a second developer disposed adjacent the photoreceptor drum including a second toner having the same predetermined first color and first color strength of the first toner and second fused gloss characteristics different than the first fused gloss characteristics.
A xerographic color image forming machine comprising:
- a first marking engine generating a first color separation toner image including:
- a first photoreceptor drum,
- a first developer disposed adjacent the first photoreceptor drum including a first toner having a predetermined first color, first color strength, and first fused gloss characteristics, and
- a second developer disposed adjacent the first photoreceptor drum including a second toner having the same predetermined first color and first color strength of the first toner and second fused gloss characteristics different than the first fused gloss characteristics;
- a second marking engine generating a second color separation toner image including:
- a second photoreceptor drum,
- a third developer disposed adjacent the second photoreceptor drum including a third toner having a predetermined second color, second color strength, and third fused gloss characteristics, and
- a forth developer disposed adjacent the second photoreceptor drum including a forth toner having the same predetermined second color and second color strength of the third toner and forth fused gloss characteristics different than the third fused gloss characteristics.
- an intermediate transfer belt receiving the first and second color separation toner images in a multi-color composite toner image;
- a transfer station transferring the multi-color composite toner image to a substrate;
- and
- a fuser fixing the multi-color composite toner image to the substrate to form a color print.
A method of forming a color print in a xerographic image forming machine comprising:
- a controller forming color toner images on a separate photoreceptor for each of a plurality of different color separations, wherein for each different color separation the forming includes using one of a first developer and a second developer disposed adjacent the associated photoreceptor, the first developer having a toner of a first color and first color strength of the associated color separation, and first fused gloss characteristics of a relatively higher gloss, and the second developer having a toner of the first color and first color strength of the associated color separation, and second fused gloss characteristics of a relatively lower gloss lower than the relatively higher gloss;
- combining the color separations to form a multi-color composite toner image;
- transferring the multi-color composite toner image to a substrate;
- and
- fusing the multi-color composite toner image to the substrate to form a color print.
