Abstract
Fluid jetting device comprising: a nozzle plate, a fluid chamber terminating in an orifice in the nozzle plate, an actuator for generating a pressure wave in a fluid in the fluid chamber to jet fluid through the orifice from the chamber, a jetting waveform generating device connected to the actuator for generating an excitation waveform comprising two separated pulses, called a jetting pulse and a quenching pulse, for respectively generating a pressure wave in the fluid in the fluid chamber leading to a fluid droplet and for substantially cancelling a pressure wave in the fluid in the fluid chamber, wherein the jetting waveform generating device is adapted to make, when jetting two consecutive fluid droplets, a first and a second droplet, the jetting pulse of the second droplet at least partially overlap the quenching pulse directly following the jetting pulse of the first droplet.
