Abstract: Systems and computer program products for performing color separation operations. In one aspect, a system creates a high-level representation of a graphical container as a separated element the first time a graphical container is used. The high-level representation being a non-bitmapped representation. The system stores the high-level representation of the graphical container in memory and refers to the separated element in memory when the graphical container is invoked a second time. In another aspect, a system creates a high-level representation of a form XObject as a separated element in a cache. The system uses the separated element in the cache when the form XObject is invoked a second time. In another aspect, a system creates a high-level representation of a pattern container as a separated element in the cache and uses the separated element in the cache when the pattern container is invoked a second time.

Abstract: A system optimizes a process for creating color separation for a document with a graphical container using a cache by creating a high-level representation of the container as a separated element in the cache; and using the separated element in the cache when the graphical container is invoked a second time.

Abstract: A method and system for correcting areas of a page that may produce hue shifts when executing a color conversion process on the page from a source color space to a destination color space. The page includes one or more objects including unspecified color points. The method includes determining when a predetermined amount of hue shift will occur in the color conversion process for the object from the source color space to the destination color space. If the amount of hue shift exceeds the predetermined amount, the method includes generating color data for all unspecified color points in the source color space and color converting the object from the source color space to the destination color space.
