Abstract

A method and system for adjusting or calibrating the colors output by an image processing system such as a full-color digital copier. After the copier is calibrated, the color balance standard within the copier is set using the calibration information. A portion of the image is printed by the copier in various tones, adjusted relative to the color balance standard. The user then selects the color balance of the image having the most acceptable color balance. Calibration of the copier can be performed by scanning a gray-scale image and adjusting the parameters controlling RGB data within the copier based on the gray-scale image which was scanned. In order to adjust the color balance for specific colors contained within an image, the user manually selects points on the image and frames having the selected color are printed, scanned, and the scanned information compared to stored color information in order to adjust the color balance to accurately reproduce the color selected by the user. As an alternative manner of performing color balance adjustment for colors of a user selected image, points on the image are sampled and a mosaic-type image printed having the sampled points. The mosaic image which has been printed is then scanned in order to perform a color adjustment process.
