Abstract
A liquid stream is caused to jet from a nozzle. A small or large drop waveform applied to a drop forming mechanism causes the liquid stream to break up into a small or large volume drop, respectively. The small drop waveform includes a pulse having a pulse energy E, and a period X, where X, and where fis the Rayleigh frequency of the liquid. The large drop waveform has a period X, where X=NX, with the large volume drop being N times the small volume drop. The large drop waveform includes a first pulse having a pulse energy E, where E≧Eand a second pulse occurring within a time period X, where X≦X, of an initial pulse of a subsequent small or large drop waveform, the second pulse including a pulse energy E, where E<E.
