Features of UJF-3042

UV LED curing technology

UV LED Curing Technology

The UJF-3042 series employs UV LED printing technology, which does not generate excessive heat, allowing the machine to print directly on virtually almost anything, including heat-sensitive materials.

Two models are available: UJF-3042FX, which can print on media up to 50 mm thick, and UJF-3042HG (up to 150 mm thick).

Three Types of UV Curable Ink

Three types of ink are available for Mimaki UJF-3042 series. LH-100 hard UV ink excels in scratch and chemical resistance as well as in colour reproduction; LF-200 flexible UV ink enables stretching of ink up to 200% during post-processing work; LF-140 offers strong gradation in 6-colour printing and is more flexible than LH-100 ink.

White ink under and overprint
Simultaneous white ink under and overprint
Print outstandingly colourful, bright images on transparent and coloured substrates with white ink under or overprint without slowing down the print speed.

A. 4/6 colours only
Without white ink as a basis for overprinting, the colours are not as vivid as they should be.

B.4/6 colours + white
With the white ink overlay print, the images are bright and vivid.

Embossed effect using clear ink Stunning effects with clear ink
Add value to your prints by using clear ink to create beautiful glossy, matte, or embossed finish–as well as to further protect your image.

Automatic Primer Application Function

Both printers incorporate an automatic primer feature, simplifying pre-priming process, which is traditionally done manually by wiping or spraying. Mimaki’s inkjet primer cartridge is simply inserted into the corresponding ink slot of UJF-3042, enabling the primer to specifically target the print image area only.

Automatic Inkjet Primer Function

*Always test your intended materials before using primer. When printing with primer and white / clear ink, production speed is reduced to some extent.

Useful Functions to Ensure Print Quality

  • Mimaki Spray Suppressor System prevents satellite ink drops, ensuring higher print reliability, consistency, and quality.
  • Nozzle Recovery Function temporarily restores print quality, reducing potential downtime if maintenance issue should arise.
  • Mimaki Circulation Technology (MCT) is a newly developed white ink circulation system that prevents pigment sedimentation and reduces ink waste. Available on UJF-3042HG.

Mimaki ECO iconEnvironmentally-friendly Technology

  • UV LEDs have longer life and consume less energy than conventional UV lamps
  • Less transfer waste and no wasted inventory by printing on-demand, direct-to-substrate
