ABSTRACT:
Electrostatic spraying of a liquid from an applicator on to a substrate. Of primary importance for spraying ink from hand-held devices or in computer graphic work. The spraying is controlled by variation of a control electrode between an operative and an inoperative state; the control electrode, e.g. a needle, being positioned so as to affect the electrostatic field when activated and prevent spraying.
