Kyocera develops world’s fastest 1200×1200dpi Inkjet Printhead


Kyocera has successfully developed the KJ4B-Z Series 1200×1200dpi high-resolution inkjet printhead for water-based ink, achieving the world’s fastest print speed of 80 meters per minute for an inkjet printhead — a key component in commercial inkjet printers. The newly-developed Kyocera KJ4B-Z Series 1200×1200dpi inkjet printhead achieves higher drive frequency by improved signal waveform that controls the piezo actuator which controls ink ejection; and by improving the ink flow channel structure. Achieving the world’s fastest print speed of 80m/min. with 1200×1200dpi resolution, this printhead is capable of ejecting up to 64,000 drops of ink per second (at 64kHz drive frequency) from each ink nozzle, resulting in approximately 330 million drops per second from a head with 5,120 nozzles.


The KJ4B-Z Series printheads provide high-resolution printing due to the high-density arrangement of piezo actuators and ink nozzles through Kyocera’s proprietary design and simulation technologies. Furthermore, the world’s largest effective print width of 108mm (4.25 inches) requires fewer printheads even for wide-format printing, which simplifies equipment design. By developing the world’s fastest, highest-resolution inkjet printhead, Kyocera strives to expand the application of on-demand commercial printing, reduce costs and shorten delivery time by contributing to the advancement of higher-speed and higher-resolution printing required in the commercial printing industry.
