Kyocera announced that it will launch the revolutionary KJ4A-EX1200-RC circulating print head in May 2025. “KJ4A-EX1200-RC” is UV-ink compatible with 1200dpi resolution, offering both high-resolution printing and high productivity printing for labels and many other applications. This new print head compatible with UV ink will redefine the digital printing industry standards and bring breakthrough print quality and production efficiency improvements.

Against the background of the rapid development of digital printing technology, the market demand for high-performance print heads is increasing day by day. Digital printing has been widely used in industries such as clothing, packaging and building materials due to its advantages of on-demand printing, environmental protection and energy saving. Especially in the field of label printing, the industry has put forward higher requirements for printing equipment: the machine needs to not only accurately reproduce fine text and smooth tonal gradients, but also make a perfect balance between high resolution and ink density. With its deep technical accumulation, Kyocera has successfully developed this print head with excellent durability and stability, providing reliable guarantee for continuous printing.

The core advantages of the KJ4A-EX1200-RC printhead are reflected in the following three aspects:

1. Innovative Circulation at the Nozzle Ensures Stable Printing
The KJ4A-EX1200-RC printhead adopts Kyocera's patented nozzle close-range circulation technology, which significantly improves printing stability through precise temperature control and inkjet ink composition management. The unique water cooling system achieves uniform distribution of the overall temperature of the printhead, effectively reducing the maintenance frequency, especially the need for cleaning when the printer is restarted. This innovative design not only extends the service life of the device, but also ensures quality consistency during continuous printing.

2. High-resolution of 1200dpi and Improved Print Speed and Drive Frequency for Optimized Productivity
KJ4A-EX1200-RC achieves an ultra-high resolution of 1200dpi, which is significantly improved in both print clarity and printing efficiency compared with previous generations. The optimized drive frequency greatly increases the printing speed, perfectly meeting the dual requirements of the label printing market for fineness and printing capacity.

3. Unique Monolithic Piezo Actuator Provides Excellent Printing Quality
Kyocera has made a breakthrough in applying its self-developed integrated piezoelectric actuators to UV ink-compatible 1200dpi printheads. The actuator uses an innovative polycrystalline ceramic structure and an ultra-thin piezoelectric ceramic substrate (116mm×34mm×0.04mm in size). Through the optimization of materials and manufacturing processes, it ensures high consistency of image quality across the entire printing area, achieving an unprecedented printing clarity.

The launch of this print head marks an important step for Kyocera in the field of digital printing technology, which will bring revolutionary changes to the printing industry and help companies achieve more efficient and higher-quality printing.
