Patent ID: 7404626

Claim:
An ink jet printing system comprising: a printhead comprising a plurality of continuous ink jets, wherein the continuous ink jets are disposed in a row and directed toward a print media, wherein the printhead comprises: a. a drop generator comprising: i. an orifice plate disposed thereon, wherein the orifice plate comprises a plurality of nozzles with each nozzle forming an ink jet, wherein the plurality of nozzles contain a first group of nozzles and a second group of nozzles, wherein the first group is in interleaved patterns with the second group, and wherein the geometry of the first group is different from the geometry of the second group; ii. a stimulating device adapted to provide a signal to both first group of nozzles and a second group of nozzles to produce a first group of drops with a first breakoff length and a second group of drops with a second breakoff length, wherein the first and the second breakoff lengths are different; b. a charge plate disposed opposite the drop generator, wherein the charge plate comprises a plurality of drop charging electrodes, wherein each drop charging electrode is positioned adjacent each ink jet; and c. a controller in communication with each drop charging electrode, wherein the controller is adapted to supply a controlled drop selection pulse to each drop charging electrodes, wherein the controlled drop selection pulse applied to an electrode affect the drop selection for the adjacent ink jet and do not affect the drop selection of other jets.
