Development of World’s fastest Drop-on-Demand Inkjet Printing by Kyocera
In recent years “ON Demand anything” is on the rise from video /audio, Movie, as well as some services in order to accommodate some individuals with their personalized taste and specialized needs. On demand printing is no exception in the business world in order to full file a larger variety of printing in smaller order volumes to meet specialized customer needs in the commercial high speed printing market where inkjet is becoming increasingly popular in full filling this need due to its flexibility on a page by page basis which contributes to productivity and its cost performance. But keeping up with this demand equipment manufacturers seek an inkjet print head capable of higher speeds, resolution and reliability. Based on this growing demand Kyocera Corporation made an announcement on development of world’s fastest inkjet print head a key component in the inkjet printing equipment. Each nozzle in the newly developed KJ4 Series printhead is capable of ejecting up to 60,000 dots per second at 60kHz drive frequency. The KJ4 comes with 2,656 nozzles per head allowing the device to print approximately 150 million dots per second. The newly developed KJ4 offers printing in three different resolution of 600×360dpi (330m/min. at 40 kHz), 600×600dpi (200m/min at 40 kHz), and 1200×1200dpi (150m/min at 60 kHz). The high speed in this newly developed KJ4 was achieved through enhancing the drive frequency. Kyocera also made the interior ink channels more compact plus it optimized the nozzle configuration and finally improving the water repellent coating on the printhead nozzle surface to prevent clogging resulting in more accurate ejection of ink. The new KJ4 series printhead supports water-based ink for printing on paper and with further development the new printhead KJ4 can use UV-curable and oil based inks allowing printing on materials such as cloth, non-absorbent films and plastics. The target material can further be expanded to textile, electronic circuitry, and other elements within electronic devices such as LCDs since inkjet system print without contacting the target material. Kyocera will display the new printhead at the Japan Graphic Arts Show 2009 from October 6 through 10 at the Tokyo Big Sight.

[...] Kyocera Corporation made an announcement earlier this month on development of industry’s first wavelength-selective crystal 1.2 wave plate enabling the multi-use and simultaneous use of three wavelengths. The newly developed 1/2 wave plate is the core component in laser equipment ensuring the required accurate processing through adjustment of irradiation power as well as process flexibility by adjusting the irradiation angle all through rotation of the laser polarization plane to achieve optimal micro fabrication suiting the pieces to be processed. Unlike the current method of using one wave plate for each wavelength, the new wave plate enables the multi use and simultaneous use of the three basic wavelengths of an Yttrium-Aluminum-Garnet (YAG) laser with a single plate resulting in compatibility with the highly versatile fundamental wavelength of the YAG laser of 1,064 nm wavelength, the second harmonic of 532 nm wavelength and the third harmonic of 355 nm wavelength. The newly developed wave plate will contribute in reducing the number of components that are required in laser devices that uses several wavelengths resulting in simpler and compact devices. Kyocera is planning to apply this technology in offering wave plates which are compatible with more than three mentioned wavelengths or other than YAG laser. Samples are currently available.
