Abstract
A multilevel printing process can be calibrated by: measuring a small number of recorded patches obtaining data points characterising the printing process, modeling a gradation of the printing process with a model curve incorporating different gradation behaviour of the printing process in different regimes based upon the obtained data points, and using the model curve to obtain a gradation-correction curve for calibrating the printing process, where it is sufficient to use only patches obtained by filling every pixel in a patch with a same recording level.
