Go Beyond Conventional Width
The UJV55-320 is a grand-format UV-LED inkjet printer delivering high-quality, super-wide output up to 3.2 meters (126") for volume production of banners, retail, exhibition, and window graphics — with the added versatility of twin-roll simultaneous printing.
Taking advantage of the full printing width, two media rolls can be mounted at once, each independently sized from 210 to 1,524mm, running the same job or two entirely different ones. High-speed mode reaches up to 110 m²/h, with seven ink colors including white for transparent or colored media.
Built for Volume, Built for Width
Features aimed at keeping a 3.2-meter machine running productively without constant operator attention.
Twin-Roll Simultaneous Printing
Mount two rolls up to 1,524mm each and run the same job on both or two completely different jobs at once, effectively doubling shop throughput.
Mimaki Proofing Panel (MPP)
An LED backlit panel lets operators check color fidelity and print quality during the run — especially useful for verifying backlit signage before it's finished.
Automatic Nozzle Check Unit
Clogged nozzles are automatically detected and cleaned by the NCU, keeping large-format jobs running without manual intervention.
GREENGUARD Gold Ink, High-Opacity White
All UJV55-320 inks are GREENGUARD Gold certified. UV-curable ink's thicker layer on media delivers much greater "blockout" performance than other print methods — particularly valuable for backlit signage, where blocking out backlighting in specific areas improves overall illuminated color performance.
- GREENGUARD Gold certified LUS-120 ink
- High blockout performance for backlit signage
- Mimaki Circulation Technology keeps white ink consistent
Ink Types
LUS-120 — 7-Color Standard
Cyan, Magenta, Yellow, Black, Light Cyan, Light Magenta, and White for wide color range and opacity control.
Bulk Ink Reservoir
External bulk ink supply keeps the 3.2-meter machine fed through long, high-volume production runs.
The 7-color set with White ink covers day/night viewing consistency, while bulk supply keeps grand-format jobs from stalling mid-run.
Gigabit Ethernet Connectivity
Fast File Transfer for Large Jobs
Gigabit Ethernet connectivity keeps large-format file transfer from becoming a bottleneck, so grand-format jobs move from RIP to print without unnecessary wait time.
