Abstract
An improved print head construction for continuous ink jet printing of the kind which directs a plurality of ink streams through a drop charge region toward a print zone. The print head includes: (i) charge electrodes located adjacent the drop charge region for selectively applying an information voltage to droplets; (ii) a deflection electrode(s) closely spaced to, and downstream from, the charge electrodes, for applying a deflection field to the droplets; and (iii) a dielectric matrix for integrally embedding the charge and deflection electrodes in closely spaced relation. Methods for fabricating such print heads are also disclosed.
