ABSTRACT:
An ink jet printing system is disclosed of the type wherein selected droplets from a continuous stream of droplets are charged and deflected toward a target. The droplet placement on the target is determined by the amount of charge. The system uses an electrohydrodynamic (EHD) exciter to generate the continuous stream. The exciter is composed of one, two, three or more pump electrodes of a length equal to about one half the droplet spacing. The multiple pump electrode embodiments are spaced at intervals of multiples of about one half the droplet spacing or wavelength.
