Abstract
A system for converting a first representation of a color input image to a second representation and method for performing same are disclosed. The system includes apparatus for mapping primary axes and overprint axes of a selected color coordinate system to primary axes and overprint axes of a printer color coordinate system of the second representation, thereby to produce primary conversion tables and overprint conversion tables and apparatus for converting the first representation to the second representation utilizing the primary and overprint conversion tables. The system also includes printing apparatus for printing the second representation and for producing an output print, wherein the output print is a reproduction of the color input image within the selected color coordinate system. Furthermore, the system enables selection of operator-selected appearance parameters used to match desired printer conditions in accordance with the appearance parameters.
