Abstract:
A method of actuating a piezo bending transducer drop-on-demand print head, the print head having a nozzle plate with a plurality of nozzles arranged in series, wherein each of a series of piezo bending transducers is respectively assigned to each of said plurality of nozzles, comprising: subjecting each of the piezo bending transducers to a sequence, corresponding to the desired print image, of triggering pulses each effecting a drop discharge movement; and, assigned to each triggering pulse, each piezo bending transducer neighboring piezo bending transducer triggered by the triggering pulse being subjected to a compensating pulse deflecting it wherein the triggering pulse has an amplitude and each of the neighboring piezo bending transducers is subjected to a compensating pulse of a lower amplitude than said triggering pulse amplitude.
