Efficient and Versatile Twin-Roll Simultaneous Printing

Taking advantage of the 3,200mm printing width, two media rolls can be mounted for simultaneous printing. Different print jobs (or the same print job) can be printed on two separate rolls. The user can select the preferred width separately for each roll, within a specified range (210 to 1,524mm).


Prevention of print quality problems – NCU

The UJV55-320 is equipped with Mimaki’s original automatic NCU. Clogged nozzles are automatically detected and cleaned by the NCU. If the clogging is not resolved by cleaning, the UJV55-320 automatically sets the nozzle recovery function NRS and resumes printing. These functions significantly reduce the waste printing caused by clogged nozzles during a continuous printing run.


Productivity maintenance – NRS

The NRS substitutes defective nozzles with non-defective nozzles until the technician arrives. This feature enables uninterrupted print operations and continuous productivity.


Print quality

Improved print head configuration
Head configuration: Four print heads in a staggered array. 1 head: 1,280 nozzles (320 nozzles X 4 lines), Y C M K 4 heads: total 5,120 nozzles.


Beautiful output

MAPS (Mimaki Advanced Pass System)
Reduces banding by dispersing ink drops between passes.

Waveform Control Technology
Ensures high quality print resolution, by jetting ink drops in straight lines with almost perfect round dots, delivering clear and sharp letters, lines and edges.

Superior inkjet technology
Delivers high density print by removing the gap between dots.


Print Speed

Print Speed (White Printing)

  • In 1200x1200dpi print mode, max. print width is 2.7m
  • Estimated speed when printed on 3.2m wide media
  • If printed on 1.5m-wide media, print speed is halved

Print Speed (4-Colour)

  • Estimated speed when printed on 3.2m wide media.
  • If printed on 1.5m-wide media, print speed is halved.

Print Speed (7-Colour)

  • In 1200x1200dpi print mode, max. print width is 2.7m.
  • Estimated speed when printed on 3.2m wide media.
  • If printed on 1.5m-wide media, print speed is halved.

Improved performance for backlit printing applications

White ink print enhancements
Printing on transparent media is made possible by the application of white ink as an under or over layer.

Inline LED lightbox for backlit print inspection
Proofing while printing LED backlights illuminate printed media just after printing, reproducing a backlit signage application and ensuring immediate quality inspection.

High ‘Blockout’ performance for backlit signage
A key feature of UV-curable ink is the thickness of the ink layer on the media, which enables much greater ‘blockout’ performance than other print methods. This is particularly beneficial in backlit signage applications where the ability to block out backlighting in certain areas improves overall illuminated colour performance and vibrancy.

A biofuel is a fuel that contains energy from geologically recent carbon fixation. These fuels are produced from living organisms. Examples of this carbon fixation occur in plants and microalgae. These fuels are made by a biomass conversion (biomass refers to recently living organisms, most often referring to plants or plant-derived materials). This biomass can be converted to convenient energy containing substances in three different ways: thermal conversion, chemical conversion, and biochemical conversion.
