Abstract
In a printing apparatus, a colorimeter is provided for performing imaging calibration on an inline scanner for inspecting a printed image. During a printing operation, the inline scanner captures a test pattern image formed on paper and thereby obtains calibration imaging data, the colorimeter performs color measurement on the test pattern image and thereby obtains calibration colorimetric data, both data are used to update a correction factor LUT for imaging calibration, and the correction factor LUT is used to perform imaging calibration on the inline scanner.
