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.
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;
A method according to any preceding claim, wherein, during said step of generating, the printheads (5) of one group (4) generate at least one first series of control zones (7a) printed with a preset nominal quantity of ink and a second series of control zones (7b ) printed with a further preset quantity of ink, said preset quantity being different from said further preset quantity.
A method according to any preceding claim, wherein the coloured zones (6;
A method according to any preceding claim, wherein the parameter that is measured is selected from a group comprising:
A method according to any preceding claim, wherein, if print anomalies are present, there is provided the step of generating an attention signal.
A method according to any preceding claim, wherein, if print anomalies are present, there is provided the step of using the measured values of said parameter for correcting measures of the calibration target.
A method according to any preceding claim, wherein the describer of the calibration target contains, for each coloured zone (6), a recipe of inks required for producing said coloured zone (6).
A method according to any preceding claim, wherein the describer of the calibration target is used by a program for generating images to be printed.
A print support, particularly conformed as a ceramic tile, comprising a surface on which a plurality of coloured zones (6;
