A calibration system for electronically-generated images includes a calibration utility 22 for modifying tone scale and/or color reproduction so that a reproduced print 10 will faithfully match a monitor image 16. An input memory 19 provides a stored image for processing by application software 20 until an acceptable monitor image 16 is obtained. If a hard copy print 20 made from the processed image does not match the monitor image 16, a printer tone scale algorithm 28 and a printer color algorithm 30 in the calibration utility 22 are invoked to match the print to the monitor. An operator adjusts tone scale controls 32 and color controls 34, which provide values for calibrating a tone scale look-up table 49 and a color matrix 48 in a printer 14. Interactive feedback is provided by inversely modifying a tone scale look-up table 44 and a color matrix 46 used in processsing the display signal. When the monitor image 16 looks "as bad as" the print, the calibration of the printer 14 is completed and the monitor 18 reverts to its original state.
