Disclosed is an inkjet print head array with improved ink supply system. The system includes an ink manifold having at least two ink supply channels, a plurality of print head modules disposed along ink supply channels and forming the array, with each of the print head modules having at least two ink inlet ports. The ports are in fluid communication with the ink supply channels. Each of the ink supply channels supplies ink to each of the ports at a different flow rate, although the resulting ink supply flow rate is equal for each print head module.
