Abstract: The invention provides a flow feature structure for an ink jet printer. The structure includes a polymeric nozzle plate having a nozzle plate thickness, the nozzle plate containing a plurality of ink chambers, each ink chamber containing a nozzle hole in fluid communication therewith, a plurality of ink channels each having a channel width and an ink channel inlet for providing ink flow from an ink supply region to one each of the ink chambers and an air bubble interrupter device having a width dimension perpendicular to a flow axis through the ink channel. The width dimension of the air bubble interrupter is from about 0.5 to about 1.2 times the ink channel width and the interrupter device is disposed adjacent each of the ink channels and spaced from the ink channel inlet a distance of from about 0.5 to about 1.2 times the ink channel width. Such a structure provides improvement in ink flow by reducing the size of air bubbles which may form or accumulate in the flow areas of the nozzle plate so that the air bubbles do not block or inhibit the flow of ink to the ink chambers or affect the ejection of ink from the nozzle holes.
