Features of UJF-6042


Increased ink dot placement accuracy for better image quality
The UJF-6042 adopted a unique ball screw type head conveyance mechanism heretofore available only in high-end flatbed printers. This improves the accuracy of the ink drop placement, which in turn prevents bandings.

UJF-6042 Ball Screw Type Head Mechanismn

Variable drops function for smooth and beautiful gradation
Variable drops function provides 3 different drop sizes at once, with a minimum drop size of 4 picoliter. This produces smooth gradation patterns and brilliant transitions of many colour layers even in the 4-color mode.

UJF-6042 Variable Drops Function


  • Mimaki Circulation Technology (MCT)UJF-6042 Mimaki Circulation Technology (MCT)
    Mimaki Circulation Technology (MCT) is a newly developed white ink circulation system that prevents pigment sedimentation and reduces ink waste.
  • Nozzle Recovery Function temporarily restores print quality, reducing potential downtime if maintenance issues should arise.


The UJF-6042 incorporates 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-6042, enabling the primer to specifically target the print image area only.

Automatic Primer Application Function

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


Three types of UV ink are available to achieve the best print results on a wide range of applications. In addition, eight ink slots enable various ink configurations, such as 6 colors plus white and clear. Furthermore, by printing different layers of ink and/or gloss, your images will not only look more enticing but also will have a raised / embossed quality that will satisfy your customers.

UJF-6042 Embossed Print


  • 3D Lenticular achieved by high definition print
    The UJF-6042 can discharge minimum 4 pl ink dots in 1,800 × 1,800 dpi, enabling lenticular printing by 3D lens of 100 lpi which has previously been difficult for existing digital printers to achieve.

    * lpi = line per inch
    * For 3D lenticular printing, dedicated software for data creation and 3D lens are required separately.

    UJF-6042 High Definition Print for 3D Lenticular

  • Unique textures on metals achieved through etching process
    Etching is a surface treatment which utilises the corrosive action of metal, through chemicals. The area which should not be corroded is covered with a mask of UV ink. Then the substrate is immersed into the corrosion solution to be corroded. With such treatment, you can achieve high quality textures, and permanent engraving.

    Etching process with UJF-6042

  • Innovative imprinting function supports variable data input
    UJF-6042 is equipped to imprint variable data such as photographs, images, texts, bar codes, numberings and QR codes by reading them from a CSV format database created by Microsoft Excel ®, etc.

    UJF-6042's Imprint Capability


  • UJF-6042 Eco-CartridgesEco-cartridges, which can be repeatedly used by changing spent ink packs, contribute to waste reduction and less ink cost
  • 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
  • No noticeable odour and no excessive noise
