Abstract
A continuous inkjet print head jets a plurality of fluid streams from an array of multiple nozzle channels. The print head includes a flow conditioning means that establishes fully developed flow in one or more regions of the print head such that substantially equal flow conditions are created at each of the inlets of the multiple nozzle channels. The substantially equal flow conditions reduce nozzle-to-nozzle variations with respect to the required trajectories of the jetted fluids to improve jet pointing and thus lead to better print quality.
