A liquid jetting device is arranged to eject a droplet of a liquid. The device includes a nozzle, a liquid duct connected to the nozzle, an electro-mechanical transducer arranged to create an acoustic pressure wave in the liquid in the duct, and an electronic control system arranged to apply to the transducer a voltage signal having a waveform configured for ejecting a droplet from the nozzle. The waveform is further configured to quench a residual acoustic pressure wave in the liquid duct and includes a jet pulse, a subsequent first quench pulse having a polarity opposite to that of the jet pulse, and a subsequent second quench pulse having the same polarity as the jet pulse.
