ABSTRACT:
In an inkjet head, both tones and smoothing can be represented suitably through use of a small number of drive waveforms. A drive waveform generator unit (46) generates drive waveforms for emitting a ink particle to form dots of a same size within one cycle that is an integral fraction of the cycle for one pixel, a print data generator unit (42) generates print data of a plurality of bits for selecting said drive waveform in said cycle for one pixel, and a head drive unit (47) drives the nozzles of said head by selecting said drive waveform in accordance with said print data. Thereby, tones and smoothing can be represented suitably, through use of a small number of different waveforms.
