Current PageWide XL Pro products feature a color uniformity calibration that is performed
by means of the integrated scanner. This procedure usually behaves good enough for
the image quality requirements of this product family, but such behavior might be slightly
worse depending on the media type that is being calibrated. The color uniformity acceptance
criteria is difficult to communicate to the customers and may incur escalations. In
this disclosure it is described an automatic procedure that allows checking and evaluating
whether the calibration results are inside specs or not.
