Patent ID: 7182421

Claim:
An inkjet device comprising: an inkjet head having multiple nozzles arranged at equally spaced intervals in a row, the inkjet head ejecting ink droplets from the multiple nozzles onto target pixels on a medium; a conveying unit that conveys the medium in a first direction relative to the inkjet head, wherein a plurality of lines are defined on the medium, each of the plurality of lines extending in a second direction that is orthogonal to the first direction; a data generating unit that generates both ejection data and timing control data from pattern data, the ejection data being generated for each of specific lines selected from the plurality of lines based on predetermined criteria, the timing control data being generated for each of the plurality of lines; a drive-waveform-generation-signal generating unit that generates a drive-waveform generation signal in accordance with the timing control data; a transfer-signal generating unit that generates a transfer signal in accordance with the timing control data; a drive-waveform generating unit that generates a drive waveform in accordance with the drive-waveform generation signal; an ejection-data transferring unit that transfers the ejection data in accordance with the transfer signal; and a control unit that controls, based on the drive waveform and the ejection data transferred from the ejection-data transferring unit, the inkjet head to selectively eject ink droplets from the multiple nozzles.
