Abstract
A color printing system includes a color monitor and printer having different color gamuts. A color chart is printed out by the printer. A light source outputs light to the color printer and a color sensor detects the light reflected from the color chart printout. The sensor outputs sensor color values representing the light received from the color chart printout. A print-preview matrix is calculated from the monitor color chart values and the sensor color values. An image is input to and displayed by the monitor and is converted into a print-preview image using the print-preview matrix. The monitor displays the monitor image and the print-preview image before printing the image.
