Abstract: The present invention implements a CMYK to CMYK pre-transform in front of at least one printer to be clustered where the transform is designed to ensure that the printers addressed through the pre-transform have substantially identical output color for substantially identical input CMYK values. As one form of implementation a method is disclosed to build CMY to CMY 3D-LUTs and 1D-LUT for K using sensors in the field. Making use of a system LUTnullCMY to CMY 3D-LUT and a K to K 1D-LUTnullimproves consistency and provides a coherent control strategy and a means to provide standardized input CMY and K values in a clustered environment so that single or multiple vendor DFEs see substantially identical CMYK values.

Abstract: A method for processing raw application data, which includes a plurality of occurrences of an object, receives a stream of the raw application data into a job inspector. The raw application data includes object raw data, which represents the object, and other raw data. The stream of the raw application data is scanned within the job inspector for identifying each of the occurrences of the object. The object raw data is transmitted to a cache manager. Data representing the object raw data is cached as a function of the object occurrences detected by the job inspector.

Abstract: An improved sliding window dictionary-based compression method limits the data within the sliding window searched to data strings occurring at each discrete match location within a plurality of predefined discrete match locations, the plurality of predefined discrete match locations comprising a set of non-continuous data positions within the window of data.
