Abstract

Abstract To produce ink droplets of variable size, the piezoelectric converter elements which are each assigned to the ink channels of a writing head are driven by an adjustable number of trigger pulses (6, 7), the repetition rate of which is tuned to the resonance frequency of the ink channel and which so follow each other in time that an ejection of a small quantity of ink from the exit opening of an ink channel, brought about by subsequent trigger pulses (7), takes place before the release of the ink volume brought about by the first trigger pulse (6) from the exit opening. <IMAGE>
