ABSTRACT:
The device comprises an electrically insulating ink container containing one electrode and a counter-electrode disposed adjacent to the jet nozzle which is laser-bored through the container cover plate. The two electrodes are excited by a voltage pulse such as to generate a spark between the ink meniscus and the counter-electrode, and to expel a plurality of ink particles, rather than a single blob. The ink can be kept in circulation between the container and a reservoir 51 by means of a pump. The meniscus can be kept outside the nozzle by means of a second nozzle coaxial to the first, or by a suitable arrangement of the ink hydraulic circuit. In the case of magnetic ink, the meniscus is pulled back by a magnetic field. The ink can also be brought in front of the nozzle by capillarity.
