The Kyocera KJ4B-QA printhead is a printhead dedicated to textiles and widely used in the Chinese textile market! Kyocera printheads are known as "aristocrats" in the industry and are famous for their high-end market positioning, strict processing accuracy, and excellent printing quality. Unique in the inkjet printhead market, Kyocera printheads have firmly occupied a place with their high prices and excellent output quality and printing accuracy.
At present, the mainstream Kyocera printheads on the market include two series, KJ4A and KJ4B, which are suitable for different types of application scenarios. Among them, the Kyocera KJ4A series is specially designed for oil-based inks, such as UV inks, and is widely used in advertising, pharmaceutical inkjet, and variable data printing of food and cigarette packages, while the KJ4B series is aimed at water-based inks, such as active inks and dispersed inks, and shines in the fields of ceramic printing, digital printing, and floor printing.
Technical Highlights and Working Principle
The technical highlight of Kyocera's printhead is that it combines Drop On Demand jetting technology and Bend mode. This innovative design is designed to give full play to the advantages of precision ceramic technology, including high output power, excellent durability, and the unique functions of large piezoelectric ceramic sheets. Drop-on-demand jetting technology accurately ejects ink droplets to the print medium based on image data requirements, while bend mode uses the bending deformation generated by the piezoelectric effect of the piezoelectric ceramic sheet to promote ink ejection.
In addition, Kyocera printheads use high-performance piezoelectric ceramics, combined with precision ceramic technology, to achieve high-speed printing needs. The stainless steel laminated structure of the printhead ensures its stability and durability. Through precise design and advanced manufacturing technology, Kyocera printheads have successfully achieved the ultimate performance in high-resolution printing and large printing widths. The principle of ejecting ink relies on the precise coordination of the nozzle hole and the built-in ink path to ensure that the ink can be accurately delivered to the nozzle hole and ejected.
Kyocera KJ4B-QA Printhead Features
The Kyocera KJ4B-QA printhead offers outstanding performance, making it a popular choice in the textile printing industry. With an ignition frequency of up to 30 kHz and a wide print width of 108.25 mm, it helps reduce the number of printhead splices needed in equipment design—ideal for seamless, high-efficiency setups.
It supports variable drop sizes of 5, 7, 12, and 18 picoliters and delivers high-resolution output at 600 x 600 dpi, meeting the demands of diverse printing applications. In addition, the KJ4B-QA is known for its excellent stability, ensuring consistent image quality even after long-term use. These features make it a widely trusted and recognized printhead in the industry.

But gold is not perfect. After multiple scrutinies from customers and hundreds of millions of textile printing tests and printing productions, we found areas for improvement. Good business operators are always open-minded and happy to let everyone point out the shortcomings of the product and then make corrections and innovate.
So what kind of improvements has the Kyocera KJ4B-QA industrial printhead undergone, and what are the results? Let's find out!
Kyocera KJ4B-QA Industrial Printhead Improvement
The Kyocera KJ4B-QA industrial print head has been continuously optimized and improved from the 7V released in 2022 to the 9V and now the 10V, achieving a significant improvement in its sealing and hydrophobic performance. After a series of structural optimizations, the durability of the print head has achieved a breakthrough. Customer feedback also shows that the life of the improved print head has been extended, and the stability of use has been higher.
While maintaining high image quality and high printing speed of its products to continuously meet market demand, Kyocera will continue to optimize and improve the print heads in order to extend their service life and stability, and is committed to promoting a more dynamic and orderly development of the printing industry.
