ABSTRACT:
In the particular embodiments of the invention described in the specification, an ink jet system has a plurality of modular ink jet arrays arranged to produce high resolution images on a substrate. In one embodiment, the ink jet arrays are formed in an ink chamber plate in rows and columns providing a hexagonal pattern with ink chambers on one side of the plate and orifice passages leading from the ink chambers to an orifice plate on the opposite side of the ink chamber plate and a piezoelectric transducer mounted adjacent to the ink chambers has actuating electrodes adjacent to each of the ink chambers. Ink supply ducts, which extend in the ink chamber plate between the rows of ink jets to supply ink thereto, have one wall provided by an orifice plate affixed to the ink chamber plate.
