| Zusammenfassung: | An apparatus and method for ejecting ink droplets from a plurality of nozzles (27) located in the front face (29) of a printhead controls front face geometries to ensure consistent image quality. A front face (29) dicing angle and a thick film insulative layer (18) 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. |
