Abstract
An inkjet printing system comprises a printhead containing multiple fluid ejection elements, each fluid ejection element containing a corresponding nozzle defined on the bottom surface of the printhead, and each nozzle configured to eject liquid onto the printing medium. The nozzles may be arranged in an array containing four or more parallel rows extending perpendicular to the process direction of the inkjet printing system. The process direction is the direction of relative motion that occurs between the printhead and the printing medium during the operation of the printhead. The spacing between adjacent nozzles in each row can be set such that the nozzle density in each row is less than 75 nozzles per inch (approximately 2.54 cm). The spacing between adjacent rows in the process direction can be set to be smaller than the spacing between adjacent nozzles in each row.
