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.

Printing Performance

Maximum Printing Speed

Up to 60 m²/h

Mimaki specifies this speed on banner material in high-speed mode at 300 × 600 dpi, 4 pass.

Print Width

3,200 mm / 126"

This is the key specification that separates the UJV55-320 from standard 64" wide-format UV printers.

Maximum Media Width

3,250 mm / 127.9"

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

Ink System

Mimaki LUS-120 UV-Curable Ink

The UJV55-320 uses Mimaki's LUS-120 UV-curable ink.

Available Ink Colors

• Cyan
• Magenta
• Yellow

• Light Magenta
• White

Ink Packaging

1-liter ink bottles

The ink supply unit can hold up to 3 liters per color.

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.
