摘要 |
The invention relates to a droplet deposition apparatus comprising an actuator (100) having a plurality of spaced piezoelectric walls defining channels, said walls having opposed sides; said opposed sides being provided with electrodes being adapted to receive electric signals to deform said walls to cause liquid in said channels to be ejected therefrom; said signals having wave forms; and a control unit (130) for defining the wave forms of said electric signals; wherein the control unit comprises means (500, 514) for providing an individually adapted signal slope of the wave form to selected electrodes (E) so as to compensate for individual channel deviations.
