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.
