KJ4A-0300 vs KJ4A-TA — Key Differences Within the KJ4A Series
| Spec | KJ4A-0300 (this listing) | KJ4A-TA |
|---|---|---|
| Resolution | 300 dpi | 600 dpi |
| Max speed | 158 m/min | 50 m/min |
| Min drop size | 4 pl | 6 pl |
| Print width | 112.35 mm | 108.25 mm |
| Ink viscosity | 7.0–7.5 mPas | 6.0–7.0 mPas |
| Best for | Ultra-high-speed single-pass aqueous / UV multi-pass | High-resolution UV single-pass labels, packaging, surprint |
The KJ4A-0300 trades resolution (300 dpi vs 600 dpi) for dramatically higher speed (158 m/min vs 50 m/min) — making it the choice for applications where throughput is the priority. The KJ4A-TA is better suited for fine-detail UV work where image quality takes precedence over speed. Contact our team to confirm which KJ4A variant your printer specifies.

Frequently Asked Questions
What is the difference between KJ4A-0300 and KJ4A-TA?
The KJ4A-0300 runs at 300 dpi with a maximum speed of 158 m/min — designed for ultra-high-speed single-pass aqueous printing and multi-pass UV. The KJ4A-TA runs at 600 dpi with a maximum speed of 50 m/min — designed for fine-detail UV label and packaging printing. The KJ4A-0300 prioritises throughput; the KJ4A-TA prioritises resolution. They are not interchangeable.
Is the KJ4A-0300 for UV or aqueous inks?
The KJ4A-0300 supports both — aqueous inks for single-pass high-speed applications (up to 158 m/min) and UV inks for multi-pass applications. The viscosity range of 7.0–7.5 mPas is optimised for these ink types. Always verify your specific ink formulation against Kyocera's KJ4A-0300 datasheet before installation.
How wide is the KJ4A-0300 print swathe?
The KJ4A-0300 has a 112.35mm print swathe — slightly wider than the KJ4A-TA's 108.25mm — with 2,656 nozzles in a 2 × 1,328 channel arrangement. At 300 dpi with a 4pl minimum drop, it delivers fast coverage across a wide print area at 158 m/min.
Do you ship Kyocera KJ4A-0300 printheads to Latin America?
