14. A PostScript-compatible printer that renders graphical objects in response to PostScript language commands indicating both device-dependent and device-independent color specifications, the printer comprising a processor, the processor being configured to perform steps comprising: in a first color rendering pipeline, converting device-dependent color specifications to internal color specifications using a calibrated n-dimensional operation, where n is greater than 1; in a second color rendering pipeline, converting device-independent color specifications to device-dependent color specifications using a standard PostScript color rendering dictionary and then passing such device-dependent color specifications into the first pipeline for further processing.
