The Mimaki UJV55-320 126" Roll-to-Roll UV-LED Printer is a super-wide-format UV inkjet printer designed for high-volume production of banners, signage, posters, window graphics, vehicle graphics, building materials, and other large-format applications.
With a maximum print width of 3,200 mm (126"), the UJV55-320 is designed for applications requiring output significantly wider than conventional 64" printers. It can also support twin-roll printing, allowing two smaller rolls to be printed simultaneously when configured with the appropriate roll holders.
The printer uses Mimaki's LUS-120 UV-curable ink, including CMYK, Light Cyan, Light Magenta, and White. White ink enables high-value applications such as transparent-media printing and three-layer color + white + color graphics for backlit signage.
Mimaki specifies printing speeds of up to 60 m²/h in high-speed mode on banner material, while its UV-LED curing eliminates the conventional drying stage, allowing prints to be processed immediately after printing.

3,200 mm / 126"
This is the key specification that separates the UJV55-320 from standard 64" wide-format UV printers.

The printer can also be configured for twin-roll printing using roll holders, supporting two rolls up to approximately 60" each.

White Ink Printing
White ink is an important feature of the UJV55-320.
It can be used to produce vivid graphics on transparent media and create three-layer printing:
Color → White → Color
This is particularly useful for backlit signage and window graphics because the white layer improves color density and visual impact.
