Kyocera Starts Mass Production of Faster Inkjet Printheads for Commercial Printing

KYOTO, JAPAN—March 26, 2012—Kyocera Corp. announced that it will start mass production in April 2012 of two new inkjet printhead products—the KJ4B-Y for water-based ink and the KJ4A-B for UV-curable ink—both offering the world’s fastest print speeds (1). New additions to Kyocera’s KJ series, the printheads are key components for commercial inkjet printers. The company will initially produce 1,000 units per month (total for both types combined) and will gradually increase production volume.

KJ4B-Y (for water-based ink)
This product provides high-resolution printing combined with a print speed that is approximately 1.3 times faster than Kyocera’s conventional products, by ejecting ink up to 40,000 times per second (at 40kHz drive frequency) from each ink nozzle, resulting in approximately 100 million drops per second from a printhead with 2,656 nozzles. This allows for higher-speed and higher-resolution printing for large-volume print jobs with individualized data, such as invoices and statements, in a short period of time using water-based ink suitable for paper printing.

KJ4A-B (for UV-curable ink)
This product provides high-resolution printing combined with a print speed that is approximately 1.5 times faster than Kyocera’s conventional products, by ejecting ink up to 30,000 times per second (at 30kHz drive frequency) from each ink nozzle, resulting in approximately 80 million drops per second from a printhead with 2,656 nozzles. This allows high-speed and high-resolution printing for an increasing number of commercial products, such as label printing for plastic and glass bottles and containers using UV-curable ink that enables printing on non-absorbent materials including films and plastics.

Features

1. World’s fastest high-resolution printing.
Kyocera improved the piezo actuator for controlling the frequency and intensity of ink ejection and the programming to achieve high-frequency drive. In addition, enhancing the nozzle shape to improve drop placement accuracy enables the world’s fastest high-resolution printing.

2. Design functionality.
Both of the new products have a print width of 4.25 inches, thus requiring a fewer number of printheads for wide-format printing, which makes design work easier. It also allows for micron-level printhead alignment, as well as easy adjustment of ink tubing and wiring.
