Kyocera develops world's fastest inkjet printhead

Kyocera Corporation has announced that it has developed the world’s fastest inkjet printhead KJ4 Series. Each nozzle in the new KJ4 Series printhead ejects ink at up to 60,000 dots per second (at 60kHz drive frequency) with 2,656 nozzles per head. The device is capable of printing approximately 150 million dots per second.

Kyoceras previous inkjet printhead offered the world’s fastest print speed when it was introduced in 2008, 150 meters per minute at 600×600dpi resolution, using a drive frequency of 30kHz. However, the newly developed printhead KJ4 sets new records for high resolution, full-colour inkjet printing, offering the worlds fastest print speeds in any of three resolutions: 600×360dpi (330m/min. at 40kHz), 600×600dpi (200m/min at 40kHz), and 1200×1200dpi (150m/min at 60kHz).
