The Kyocera KJ4A-EX1200-RC is a 1200dpi industrial-grade piezoelectric inkjet printhead developed by Kyocera for UV-curable and other high-viscosity inks. It is primarily used in label printing, flexible packaging, sign and display graphics, and offset surprint applications. Powered by Kyocera’s proprietary large monolithic piezoelectric ceramic actuator, the printhead delivers uniform, high-resolution output with consistent color even at high operating speeds—making it especially well suited to the label market’s demanding requirements for fine text and smooth gradients.

The printhead features an ink recirculation structure that continuously circulates ink around the nozzles, suppressing the sedimentation of ink components and maintaining uniform temperature. This enables compatibility with a wide range of inks, reduces the risk of nozzle clogging, and minimizes routine maintenance such as cleaning at printer restart, ensuring stable jetting throughout long, continuous production runs. Combined with a standard water-cooling system, it keeps the driver board and printhead at a constant temperature—even when ink is heated to lower its viscosity—so print quality stays consistent from start to finish. With its balanced performance in resolution, speed, and durability, the Kyocera KJ4A-EX1200-RC helps users boost productivity and control operating costs, making it an ideal printhead choice for UV digital printing equipment.
