Abstract
A method of correcting measured image data deviations of an image inspection system determining image data using a single measuring head and image measuring unit, by using a computer, includes measuring color spectrums of color fields using the head and unit, creating a color set from color spectrums of the head and unit, calculating spectrums from overprinting color combinations for the head and unit using a color model and the respective color set, calculating Lab color values for the head and unit based on spectrums of the head and unit, determining deviations between color values of the head and unit for supporting points, adding determined deviations to the color values of the measuring unit at the supporting points, creating an ICC profile based on corrected color values of the measuring unit for converting imprecise measured values thereof into accurate color values, and correcting imprecisely measured values of the measuring unit using the profile.
