Abstract
A method of printing uses a multi-nozzle ink jet print head having a pressure modulator for causing streams of ink emitted from the nozzles to be broken up into individual droplets. The nozzles are divided into a plurality of groups of nozzles, and groups of charge electrodes correspond, each group of charge electrodes having a respective charge controller. In the method a modulation waveform is generated to operate the pressure modulator to cause droplets to be generated in each stream. The charge controllers are operated to supply a charge signal waveform to charge electrodes and charge droplets in the streams. The phase relationship of the charge signal waveform is adjusted relative to the modulation waveform.
