Kyocera KJ4B-QA06NTB Printhead – High-Speed Water-Based Ink Solution for Document & Textile Printing

Kyocera KJ4B-QA06NTB Printhead Description

The Kyocera KJ4B-QA06NTB is a next-generation piezoelectric printhead engineered specifically for high-speed printing using water-based inks, including aqueous, pigment-based, and specialized formulations such as MICR ink. With a maximum drive frequency of 30 kHz and a 5 pl droplet volume, it delivers sharp, consistent output at line speeds up to 76.2 m/min, making it ideal for high-throughput environments.

This single-color printhead features 2,656 nozzles arranged across a 108.25 mm wide print swath with a 0.042 mm nozzle pitch, enabling high-density printing at 600 × 600 dpi. The design supports both single-pass (e.g., transactional printing) and multi-pass (e.g., textile printing) workflows, offering flexibility across diverse industrial applications.

Key engineering enhancements include:

Internal ink filters to prevent clogging from particulates

Integrated heater to stabilize ink viscosity under varying ambient temperatures

Optimized ink channel geometry for stable flow and reduced pressure fluctuations

These features ensure reliable performance in demanding environments where ink stability and long-term uptime are critical.

Key Notes

Higher Frequency: Compared to the KJ4A series, the KJ4B offers a 30 kHz drive frequency, enabling faster jetting and improved throughput.

Ink Compatibility: Optimized for water-based inks, including low-viscosity aqueous dyes and pigments; suitable for MICR ink used in banking and financial printing.

Thermal Management: Internal heater helps maintain consistent ink properties in fluctuating environments, reducing print defects caused by temperature drift.

No Recirculation: Does not support nozzle recirculation; requires precise ink system control and regular purging to maintain reliability.

Drop Volume: 5 pl enables fine detail and low ink consumption—ideal for text, barcodes, and variable data printing.

Typical Applications

• Transactional and document printing (invoices, receipts, forms)
• Security printing (checks, banknotes, ID cards with MICR)
• Direct-to-textile printing (garments, fabrics)
• Label and packaging overprint with water-based coatings
• Industrial marking and coding
