2012-03-26 KYOCERA Starts Mass Production of World's Fastest Inkjet Printheads for Commercial Printing

KJ4 Pioneering the digital printing world with high-performance products
Wide Print Width: 108mm   High Speed: 100m/min* as Maximum
Achieved in Single Pass Printing
Wider printing coverage with fewer printheads

A wide print-width can be covered with fewer printheads by employing Kyocera’s 108mm-wide device. The enhanced width also reduces the burden of printhead alignment and tubing/cabling requirements at the inkjet printer assembly.
  Wide Print Width: 108mm

The 2,656 nozzles per printhead are each arranged in 0.042mm pitch in a 108mm print width to eject 40,000 drops per second, meaning over 100 million drops a second per printhead, printing 600dpi × 600dpi in single–pass applications at up to 100 meters per minute.*

* Under conditions of 40kHz drive frequency

High Image Quality: 600dpi Grayscale   High Reliability
High image quality with high resolution and grayscale

The unique technology in Kyocera’s piezoelectric actuator enables 600dpi × 600dpi image quality with up to five levels of grayscale by controlling drop size.
Outstanding reliability for Continuous Printing

Internal filters eliminate foreign objects, internal heaters adjust the impact of exterior temperature, and a unique ink-channel design provides stable ink supply to all 2,656 nozzles without any missing lines even for continuous printing.

 Kyocera KJ4 Series Inkjet Printheads

The KJ4A Series is designed for UV curable inks and other inks with high viscosity. It is optimal for commercial printing on a wide range of media including offset surprint and labels.

The KJ4B Series is designed for water-based inks; it achieves high-speed printing at a maximum of over 100 million drops per second. This enables high productivity in single-pass applications, such as transaction printing, documents, security printing using MICR ink, and multi-pass textile printing.

Kyocera inkjet printheads are applicable not only for printing on paper but for textile or non absorbable media such as plastic films by using appropriate inks among aqueous, UV or oil based types. Furthermore, a higher variety of applications are to be expected in the future. Expanding Inkjet Applications

 Inkjet Printheads 300dpi
The World’s Widest & Fastest 300 dpi Printhead*1 Offering Simultaneous Two-Color Printing with a single Printhead
300dpi two-color printhead

This product achieves simultaneous two-color printing with just one printhead.This not only effectively halves the number of printheads required in the printer, but also reduces the cabling requirements, contributing to a reduction in the size of inkjet printers.
