1. A system that renders print jobs via a marking engine, comprising: a raster image processor that receives the job from the input module and renders it to one or more raster images; one or more contone image processors that receive the one or more raster images to perform cross-channel image processing to render the raster images into a form compatible with the marking engine, wherein an output from the one or more contone image processors is partially sub-partitioned by color separation; an image refactoring and distribution network that completes the sub-partitioning by separation of the rendered contone raster images by color separation and distributes each color sub-partition to a marker channel module specific to each color sub-partition; and a marking engine that receives the color sub-partitioned image data, marks the image onto a substrate and outputs a hardcopy of the image.
