Abstract
A method of driving an electromechanical converter of a print head of a continuous inkjet printer, wherein the electromechanical converter is arranged to break up a continuous stream of ink into a plurality of drops. The method includes determining a modulation voltage to drive the electromechanical converter, at least a property of the modulation voltage being controlled to take into account movement of a break up point of the continuous stream of ink, and to ensure that in a characteristic of modulation voltage versus a property at least indicative of a break up point of the continuous stream of ink, the characteristic has a predetermined gradient, or a gradient related to this predetermined gradient; and driving the electromechanical converter at the determined modulation voltage.
