Product Overview


Mimaki UJF-6042

Supports A2 size & 150 mm height
to provide higher image quality than ever before


A variety of different materials from plastics, glass, and metals can now be printed onto many applications.
Using a unique ball screw type conveyance mechanism to produce higher resolution prints. The 1,800 x 1,800 dpi, variable dot technology, with minimum drop size of 4pl, achieves impressive high quality images.

The UJF-6042, allows you to print on promotional products, awards and gift merchandise along with industrial components and accessories.

Higher image quality than ever before

Ball/Screw drive linier actuator technology allows for dot placement and image quality with precision accuracy

Adopted a unique ball screw type head conveyance mechanism that had been equipped only in high-end machines. It improved the accuracy of the ink drop onto the substrate. This precise ink dot placement can prevent bandings substantially.

Furthermore, a high resolution print mode of 1,800 x 1,800 dpi has been added to achieve highly precise printing output.


Smooth and beautiful gradation achieved by Mimaki’s unique head control technique

Variable drops function provides 3 different drop sizes at once.
The minimum size is amazingly 4 pico-litter and ensures a photographic type image offering smooth gradation patterns and brilliant transitions of many color layers even in the 4-color mode.


The heritage of state-of-the-art functions

Ecological & economical applications of white ink

MCT (Mimaki Circulation Technology) was developed and designed to circulate the white ink formulations to improve stability and dispersions of the pigments in the fluid reservoir and ink path.
Advantages of less white ink maintenance down time and avoids clogging issues while in the bulk ink receptacle and overall jetting of the white UV LED inks.
* MCT works only with white ink.


Automatic primer application function

Usually primers are applied separately in a manual application process, but the UJF-6042 incorporates an automatic primer application function. The new inkjet primer cartridges are simply inserted into the corresponding ink slot, enabling the primer to specifically target the print image area only.
* Inkjet primer cannot be used in conjunction with LF-200 inks.


Nozzle recovery function

Even if nozzle washing has no effect on a troubled nozzle, the print image quality can be retained immediately.
During this nozzle downtime, this nozzle recovery function enables printer to produce high quality prints continuously without slowing down the printing process.


Multiple UV ink type options to fulfill your requirements

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.
UV-Curable ink


LH-100:Hard UV Ink (C/M/Y/K/W/Lc/Lm/Cl/Pr)

Excels in scratch and chemical resistance.
Hard UV ink with fine color repeatability.


LF-140:Flexible UV Ink (C/M/Y/K/Lc/Lm/W/Cl/Pr)

6 color inks including light color inks, express smooth gradation,
and show flexibility.


LF-200:Flexible UV Ink (C/M/Y/K/W)

Enables stretching of ink up to 200% with high adhesion.
Applicable to several kinds of substrates.
Flexibility:Very good

  • Ink type and color configuration must be chosen at the time of installation.
  • Ink flexibility of LF-140 ink and LF-200 ink may vary according to the substrate; please verify your substrate in advance.
  • Clear ink is not available for LF-140 ink. However, LH-100 clear ink can be used in combination with LF-140 ink.
  • The print mode of 1,800 x 1,800 dpi and 4 pl variable drops cannot be used in conjunction with LF-200 inks.


Highly refined environmentally friendly functions

UV LED offers reduced energy consumption, longer lifetime and almost no VOC* emissions during printing.
* VOC = Volatile Organic Compounds


You can choose the eco-cartridge method which contributes to waste reduction and reduced ink cost.
Eco-cartridges can be repeatedly used by changing spent ink packs.



Applications:Special finish which enhances added value

“3D Lenticular” achieved by high definition

This printer can discharge minimum 4pl ink dots in 1,800×1,800dpi. It enables lenticular printing by 3D lens of 100 lpi which had been deemed difficult to accomplish for the existing digital printer.
* lpi = line per inch
* For 3D lenticular printing, dedicated software for data creation and 3D lens are required separately.


“Etching process” creates unique textures on metals

Etching is a surface treatment which utilizes the corrosion action of metal. thru 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.
