Abstract: An ink jet printing system includes: a print head including multiple fluid ejectors, each fluid ejector including a corresponding nozzle defined in a bottom surface of the print head, each nozzle configured to eject a liquid onto a substrate. The nozzles can be arranged in an array including four or more parallel rows, the rows extending along a direction that is perpendicular to a process direction of the ink jet printing system. The process direction is the direction of relative motion between the print head and the substrate during operation of the print head. A spacing between adjacent nozzles in each row can be such that a nozzle density in each row is less than 75 nozzles per inch. A spacing between adjacent rows in the process direction can be less than the spacing between adjacent nozzles in each row.
