In the particular embodiments of the invention described in the specification, an ink jet system has a plurality of modular ink jet arrays (40) arranged to produce high resolution images on a substrate. In one embodiment, the ink jet arrays are formed in an ink chamber plate (47) in rows (32-39) providing a hexagonal pattern with ink chambers (48) on one side of the plate and orifice passages (49) leading from the ink chambers to an orifice plate (50) on the opposite side of the ink chamber plate and a piezoelectric transducer (54) mounted adjacent to each of the ink chambers. Ink supply ducts (44, 45), which extend in the ink chamber plate between the rows of ink jets (40) to supply ink thereto, have one wall provided by the orifice plate affixed to the ink chamber plate.
