Controller for inkjet apparatus |
摘要 |
An ink-jet head controller generates drive waveforms selectively at predetermined print cycles to cause ink ejection from a cavity. A waveform generator generates a plurality of waveform signals, including a waveform signal extending over two adjacent print cycles, and a waveform selector selects and outputs to the ink-jet head one of a plurality of waveform signals, based on whether dot data for two adjacent print cycles indicates ink ejection. The waveform selector selects a waveform signal extending over two adjacent print cycles when dot data for a current print cycle indicates ink ejection while dot data for a next print cycle indicates no ink ejection. In addition, a plurality of drive pulses cause ejection of a plurality of ink droplets to form a dot outputted after a certain delay from the start of the current print cycle.
