KYOCERA Starts Mass Production of World’s Fastest Inkjet Printheads for Commercial Printing
New printheads eject approximately 100 million drops/second (water-based ink) and 80 million drops/second (UV-curable ink)
27 March 2012
Kyoto/Neuss – Kyocera Corporation today 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*. 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.
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.
3. Applicable to various types of printing
The product lineup includes both water-based and UV-curable inks. This makes it possible to print not only on paper but also on a variety of other materials such as fabrics and plastic films. Because inkjet systems print without contacting the target material, this technology is expected to be used in a wider range of applications such as printing on textiles and printed electronics (e.g. printing and manufacturing of electronic circuits).
4. High reliability
Breaking the world's fastest print speed record, these new products also deliver the same drive durability performance as conventional products, where drive durability performance (ink ejection frequency) represents product durability. Furthermore, employing an externally sealed structure ensures the high reliability required for commercial printing.
Printing equipment manufacturers are aggressively developing new products in response to recent demands in commercial printing for smaller lot size, shorter delivery time, inventory reduction and variable printing**. Kyocera’s KJ series high-speed and high-resolution printheads, including these new products, will contribute to the advancement of the printing industry.
* The world’s fastest in single-pass inkjet printheads that print with a resolution of 600dpi x 600dpi, with a width of 4.25 inches, and one head for feed direction. Based on research by Kyocera (as of March 22, 2012).
** Variable printing: A printing method by which individually unique data (e.g., individual content of private ledger sheets, each of which is different from the other) is printed.
