•     Corrugated cardboard and packaging
•     Textiles and home furnishings
•     Coatings, varnishes, functional layers
•     Coding & marking
•     Additive manufacturing / 3D printing.

Compatibility Notes

Commonly used in wide-format LED-UV line-head systems, including platforms such as:

•     EFI Vutek Nozomi 18000+ LED (reference platform).

Always verify waveform, ink, and mechanical integration with your system integrator or OEM.

Why Choose the RC1536L?

•     Highest productivity in the RC1536 family (2,477 µL/sec).
•     Excellent reliability thanks to real-time ink recirculation and isolated channel design.
•     Flexible greyscale from 25 pL up to 225 pL for both fine detail and heavy coverage
