The Kyocera KJ4A-AA UV Printhead is an industrial-grade 600 dpi inkjet printhead specifically engineered for high-speed UV-curable and high-viscosity ink applications. Designed for demanding single-pass and multi-pass digital printing systems, it delivers exceptional jetting precision, continuous thermal stability, and maximum uptime across label packaging, sign graphics, and offset surprinting applications.
The Kyocera KJ4A-AA represents the benchmark in high-resolution, high-speed industrial piezo inkjet technology. Featuring an active print width of 108.25 mm powered by 2,656 precision-engineered channels, this native 600 dpi printhead enables high-density single-pass configurations while drastically reducing carriage pass requirements in multi-pass architectures. Operating at a drive frequency of up to 20 kHz, it drives production line speeds up to 50 meters per minute at full resolution.
Constructed with dual integrated thermal control and physical particulate filtration systems, the KJ4A-AA guarantees consistent droplet trajectory and volume uniformities. Its internal heater compensates for high-viscosity UV ink formulations, stabilizing ink rheology before entering the nozzle chamber, while the internal stainless-steel filter shields micro-nozzles from downstream particulate contamination.
