Abstract
A method is provided for characterizing color separation misregistration of a printer device, the method including receiving from the printer device an output image having marked calibration patches having a variety of color separation configurations, each using a first and second color separation, and a marked measurement patch having a predetermined color separation configuration. Measured colorimetric values are received corresponding to the calibration patches and the marked measurement patch, and a characteristic of a curve associated with the measured colorimetric values corresponding to the calibration patches is determined. A calibration function is generated based on the determined characteristic of the curve, providing expected colorimetric values for the predetermined color separation configuration as related to a misregistration characteristic value. A misregistration characteristic value is determined from the calibration function that corresponds to the measured colorimetric value of the marked measurement patch for characterizing misregistration between the first and second color separations.
