Abstract:
1. A method of producing ink drops in a printing apparatus comprising: providing a set of waveform sequences to a control circuit associated with at least one nozzle, the set of waveform sequences including at least one waveform sequence for the creating one or more print drops and at least one waveform sequence for creating one or more non-print drops; sending print-nonprint pixel data from a controller to a control circuit associated with the at least one inkjet nozzle; wherein the print-nonprint pixel data includes data on a current pixel and data on at least one previous pixel; selecting a waveform from the set of waveforms based on the print-nonprint pixel data; supplying the selected waveform to an ink drop formation device associated with the at least one nozzle; and producing an ink drop from the at least one nozzle.
