METHOD FOR CONTROLLING A COLOUR CALIBRATION TARGET

摘要

A method includes the step of printing a calibration target with a printing device, the printing device including a plurality of groups of printheads, the printheads of the same group being fed with ink of the same colour, the calibration target including a plurality of coloured zones that are intended to be subsequently processed, the method further including the steps of:
generating a series of control zones printed by the printheads of a group with the same nominal quantity of the corresponding ink, the control zones being free of overlapping between inks applied by different printheads;measuring a parameter of each control zone;comparing the measured values of said parameter for evaluating whether the control zones exhibit print anomalies.

1. A method comprising the step of printing a calibration target with a printing device (1), said printing device (1) comprising a plurality of groups (4) of printheads (5), the printheads (5) of the same group (4) being fed with ink of the same colour, the calibration target comprising a plurality of coloured zones (6; 106) that are intended to be subsequently processed, the method further comprising the steps of:
generating a series of control zones (7; 107) printed by the printheads (5) of a group (4) with the same nominal quantity of the corresponding ink, the control zones (7; 107) being free of overlapping between inks applied by different printheads (5); measuring a parameter of each control zone (7; 107); comparing the measured values of said parameter for evaluating whether the control zones (7; 107) exhibit print anomalies, in order to determine whether the calibration target has been correctly printed; if no print anomalies are present, processing at least one measurement of each coloured zone (6; 106) for obtaining a describer of the calibration target or a colour profile of the printing device (1).
