An inkjet printhead that has a silicon wafer substrate that defines a plurality of ink inlet channels and a plurality of replicated nozzle arrangements positioned on the substrate to receive ink from the ink inlets and eject ink droplets onto a media substrate. Each of the nozzle arrangements has nozzle chamber walls, and a roof positioned on the nozzle chamber walls defining an ink ejection port. The roof defines a recess about the ink ejection port to inhibit ink spread from any nozzle face floods.
