Kyocera will use Drupa to introduce a new inkjet printhead with ink recirculation technology at the nozzle. The new KJ4B-EX600-RC is compatible with a wide range of inks over a wide range of materials and applications.

This new printhead also incorporates a water cooling system as a standard, enhancing stability in continuous, high-speed, high-quality printing.

By optimising the inkflow-channel design and printhead structure, the maximum drop volume of ink ejected from nozzles has been increased to 14pL, about 17% greater than the previous model at a driving frequency of 40 kHz, with improved jetting stability. It offers an effective printing width of 108.3mm.

Kyocera has developed a large monolithic piezoelectric actuator, using proprietary material design technology for dense polycrystalline ceramic actuators, and manufacturing technology for thin piezoelectric ceramic substrates. Kyocera has now optimized and adopted the technology for this new printhead (width 116mm x depth 21mm x thickness 0.04mm).
