Method and apparatus for providing a color-balanced multiple print engine
First Claim
1. A method for processing a print job for printing on a system having multiple marking engines, each marking engine having an associated color space, the method comprising:
- receiving a print job defined according to a first color space; and
processing the received print job for routing to a selected marking engine to provide rasterized image data in the color space of the selected marking engine, wherein processing includes converting the print job data to the color space of the selected marking engine, wherein converting is performed on the rasterized image data, and wherein converting comprises;
referencing all print engines to a common color space;
translating the print job data from the first color space to the common color space; and
balancing the print job data designated for a selected marking engine to the color space of the selected marking engine, wherein balancing comprises correcting the print job data expressed in common color space format according to predetermined color calibration values corresponding to the selected marking engine.

Abstract
A method and apparatus is disclosed for color balancing page data, from a variety of input sources having non-consistent device color profiles, among a plurality of individually accessible print engines arranged in a system for color printing multiple copies of multiple page documents. Input page data is converted to a common color space, rasterized and routed to a selected print engine. Page data routed to each marking engine is color balanced to the selected marking engine where at least a portion of the color balancing occurs following the rasterizing of the page data.
