Abstract
The method and system for printer color calibration use a combination of a full-width array (FWA) or similar page-scanning mechanism in conjunction with a spectrophotometer color measurement system in the output path of a color printer for measuring colors with or without requiring any manual operations or operator involvement. The automatic color balance control system produces spatial tonal reproduction values for the primary colors by printing patches, measuring colors using the sensor combination and automatically readjusting the spatial tone reproduction curves until a satisfactory level of printed color accuracy and uniformity are obtained.
