Abstract
The uniformity of performance of inkjet nozzles within a print head containing a plurality of said nozzles is optimized by characterizing one or more performance attributes of the nozzles within said print head. A waveform set is generated that comprises a plurality of waveforms to compensate for variations of the one or more performance attributes among the nozzles. One of the waveforms within the waveform set is assigned to each nozzle to optimize the one or more performance attributes of each nozzle relative to each other nozzle in the print head. Based upon the waveform assigned to each nozzle, each nozzle in the print head responds substantially uniformly relative to each other nozzle in the print head.
