Patent ID: 8091983

Claim:
A printhead comprising: a nozzle cluster including a first nozzle and a second nozzle spaced apart from the first nozzle, the first and second nozzles having a nozzle geometry; a liquid delivery channel in liquid communication with the nozzle cluster to provide liquid that is under pressure sufficient to cause a first liquid jet to be emitted from the first nozzle at a first angle and a second liquid jet to be emitted from the second nozzle, the first angle and the second angle being nonparallel relative to each other; and a drop forming mechanism configured to from large volume drops and small volume drops from the first liquid jet emitted from the first nozzle and the second liquid jet emitted from the second nozzle, the nozzle geometry of the first nozzle and the second nozzle being shaped to control the first angle of the first liquid jet and the second angle of the second liquid jet relative to each other such that large volume drops formed from the first liquid jet and large volume drops formed from the second liquid jet contact each other or coalesce while the small volume drops formed from the first liquid jet and small volume drops formed from the second liquid jet do not contact each other or coalesce.
