Abstract
A method and apparatus for addressing the problem of combining a plurality of Page Description Language (PDL) separation color files to create a display list of objects that represents the composite or combined output image as described by the PDL separation files. Furthermore, any conflicts about the z-order of the display list is resolved by correctly ordering the objects in the display list to the extent that the ordering is significant. The need to produce a display list of objects that represents the composite or combined output image arises from digital preproofing, a technique of proofing and editing the output color image for production from images obtained from a proofing device other than the actual production printer.
