Abstract
Methods and systems of ejecting ink drops from an inkjet printer are disclosed. The methods and systems can include a printhead with one or more stepped nozzles each with an associated entrance diameter and exit diameter. Ink can be received into the printhead and formed into ink drops in the stepped nozzles. The ink drops can each have an associated drop mass and drop speed. The stepped nozzles can be provided such that the exit diameter can independently dictate the drop mass and the entrance diameter can independently dictate the drop speed. As such, the complexity of jet design optimization is reduced.
