Abstract
An apparatus and method for ejecting ink droplets from a plurality of nozzles located in the front face of a printhead controls front face geometries to ensure consistent image quality. A front face dicing angle and a thick film insulative layer etchback are controlled to maintain a Spot Aspect Ratio of each of the droplets ejected from the printhead within a predetermined acceptable range. The Spot Aspect Ratio may be maintained by control of an effective meniscus tilt angle.
