Kyocera has unveiled its next generation of inkjet printheads for commercial digital printing equipment. The new printheads are designed to deliver high-speed, high-quality printing on paper, cardboard, plastic, fabric, and other building materials. Kyocera will introduce a 600-dpi model in April 2020, with others to follow.

Kyocera first applied its proprietary fine ceramic technology to create piezo actuators for its KJ4 series inkjet printheads in 2007, and the new KJ4 EX series builds on this legacy with a large, integrated piezo actuator. By increasing the volume of each drop of ink ejected from the printheads and enhancing droplet-ejection consistency, the new series allows high-resolution printing on a wider variety of media. At the same time, the printhead’s durability is claimed enhanced by improving its structural strength and rigidity.
The larger integrated piezo actuator replaces multiple smaller actuators to enable more consistent image quality. It was created using the company’s unique material design technology for dense polycrystalline ceramic actuators, combined with its thin piezoelectric ceramic substrate manufacturing processes.
An optimized ink channel design and revised structure allows the KJ4 EX to maximize volume of ink-drop ejected and improves ink-ejection consistency. This allows the printheads and media to be separated by a greater distance without affecting droplet accuracy — ensuring high-resolution printing on a wider variety of materials, including unconventional print media.
