Abstract:
1. A control method for controlling printing by a binary continuous inkjet printer provided with a printhead, or a printhead of such a printer in order to print a pattern on a printing medium in motion relative to the head, the method comprising: determining information on a relative position of the printing medium in relation to the printhead; supplying each of a pair of electrodes with alternating voltage in phase opposition relative to each other; sending pulses to actuators to form, from a break of a jet discharged by a nozzle in communication with a stimulation chamber to which one said actuator is mechanically coupled at a distance from a plane of the nozzle, drops not able to be electrically charged by deflection electrodes or jet segments subject to electrostatic influence of the deflection electrodes; and controlling said pulses so as to minimize a total electric charge on the jet segments, said total electric charge being contained inside an electrostatic influence volume of the deflection electrodes, wherein the printhead comprises
