Abstract: An apparatus provides precise steering of inkjet droplets to a substrate by use of multipole arrangement with electrodes on a resistive plate. There may be droplet detection based on charge sensing. A hexagonal spiral deposition pattern on a target substrate allows fast uniform printing covering a nearly circular hexagonal area. There may be six electrodes arranged to form a cubic enclosure, and injected droplets may be merged within the enclosure, and their charge controlled by merging of source droplets of differing charges to provide a net charge for biasing onward steering.
