Abstract
A column of ink ejection nozzles on an ink jet print head is arranged in a plurality of sub-columns. The number of sub-columns and the assignment of nozzles to the sub-columns is selected to reduce cross-talk between nozzles, to prevent overlap of ejection pulses between sub-columns, and to minimize the complexity of the electronics required to actuate the ink ejection nozzles for droplet deposition.
