  • Patent number: 6057929
    Abstract: A system is disclosed for producing a plurality of substantially identical prints using a plurality of dissimilar printer systems. Each of the substantially identical prints are generated from a neutral data file defining a print image and an image characteristic data file defining an attribute of the print image. The image characteristic file provides an original absolute value for specifying the attribute. The system includes a first printer system and a second printer system, both responsive to the neutral data file and the image characteristic data file for producing a first print and a second print, respectively. The attribute on the first print has a first original actual value corresponding to the original absolute value provided to the first printer system by the image characteristic data file, and the attribute on the second print has a second original actual value corresponding to the original absolute value provided to the second printer system by the image characteristic data file.
