Abstract

Der Druckkopf hat eine Vielzahl nebeneinander angeordneter Kanäle (3) mit piezoelektrischen Scher-Wandlern. Die Impulsform zur Aktivierung der Wandler wird abhängig von der Anzahl gleichzeitig aktivierter Nachbarkanäle so geändert, dass die Austrittsgeschwindigkeit der Tintentröpfchen konstant ist. Dadurch kann ein besseres Druckbild erreicht werden.

Figure 00000001
The printhead has a large number of channels (3) arranged next to one another with piezoelectric shear transducers. The pulse shape for activating the transducers is changed depending on the number of adjacent channels activated at the same time so that the exit velocity of the ink droplets is constant. This enables a better print image to be achieved.
