Abstract:
1. A method for characterizing color separation misregistration of a printer device using color separations of a color space for marking a substrate, the method comprising: receiving by a tangible processor a colorimetric value corresponding to a colorimetric measurement of respective patches of a plurality of patches included in an output image output by the printer device, each patch of the plurality of patches having markings of a first and second color separation of the color space, wherein: fitting a single curve to the received colorimetric values associated with each of the patches of the plurality of patches; characterizing by the processor misregistration of the first color separation relative to the second color separation using the curve; determining by the processor a peak received colorimetric value for a patch series of the at least one patch series; determining by the processor a magnitude of the displacement that corresponds to the peak; and determining by the processor an offset between the determined displacement magnitude and an expected displacement magnitude corresponding to an expected peak colorimetric value associated with ideal color separation registration; wherein the characterizing of the misregistration is further based on the determined offset.
