Claim:
1. A method for optimizing the uniformity of performance of inkjet nozzles within a print head containing a plurality of said nozzles, comprising: characterizing one or more performance attributes of said nozzles within said print head; generating a waveform set comprising a plurality of waveforms to compensate for variations of said one or more performance attributes among said nozzles; assigning one of the waveforms within said waveform set to each said nozzle to optimize said one or more performance attributes of each said nozzle relative to each other nozzle in said print head; wherein, based upon said waveform assigned to each nozzle, each nozzle in said print head responds substantially uniformly relative to each other nozzle in said print head; using performance of a predetermined portion of the nozzles comprising nozzles in a central portion of said print head as a baseline; and adjusting nozzles comprising nozzles outside of said central portion of said print head and not comprising nozzles within said predetermined portion by assigning a waveform to said outside nozzles to adjust said outside nozzles to approximate performance of the nozzles within said predetermined portion.
