ABSTRACT:
A system for electrostatic printing including a corona source and electrode for coulombs/m.sup.a substantially uniform stream of ions in the direction of a print receiving medium and a multilayer apertured modulator interposed in the ion stream for modulating the cross-sectional flow density of ions in the stream in accordance with a pattern to be reproduced. A cloud of substantially uncharged liquid aerosol ink particles is introduced adjacent the print receiving medium whereby the modulated ion stream selectively impinges upon and charges particles in the cloud which are thereby accelerated and deposited on the print receiving medium in accordance with the pattern to be reproduced. The average surface charge density on liquid aerosol particles in the cloud is no greater than about 1 .times. 10.sup.-.sup.6 coulombs/m.sup.2, and preferably no greater than about 5 .times. 10.sup.-.sup.7 coulombs 2. The liquid aerosol droplets are in the range of from about 0.10 micron to 50.0 microns in diameter, the range of 1.0-10.0 microns diameter being preferred.
