Controlling method for color calibration target to be used during digital printing process involves processing measurement of colored zones for obtaining describer of calibration target if no print anomalies are present

摘要

A calibration target is printed by means of a printing device comprising a plurality of groups of printheads. The printheads of each group are fed with ink of the same color. The calibration target includes a plurality of colored zones that are intended to be subsequently processed. The printheads of each group further generate a series of control zones with the same nominal quantity of the corresponding ink. The control zones are free of overlapping between inks applied by different printheads. A parameter of each control zone is measured and the measured values of this parameter are compared to each other in order to assess whether the control zones exhibit print anomalies.
