  • Specifications are subject to change without notice.
  • All trademarks or registered trademarks are the property of their respective owners.
  • Inkjet printers print using extremely fine dots, thus colors may vary slightly following replacement of the printing heads. Also note that if using multiple printer units, colors may vary slightly among the units due to slight individual differences among the units.


Precautions for UV printing

 Inks and substrates:

  • Please note that properties and adhesion, weather resistance etc. of ink and substrates can vary. Therefore please test materials before printing.
  • Some substrates require primer before printing. Please test materials beforehand or ask your sales representative.


 Safety notice:
You are dealing with UV light sources that may harm your health. Please follow below guidelines strictly:

  • Do not look directly into the UV light source nor place your hand, or expose your skin directly to the UV light source.
  • Depending upon print mode, there might occur some VOC emittance from printed parts not yet cured and hardened.
  • In addition, please read the instructions and guidelines of the manual carefully and follow those.
1. Inkjet primer improving the ink adhesion

While the ink adhesion with the material is not sufficient, applying the inkjet primer will help. The primer can be applied to the desired areas by ink-jetting. This feature retains the texture of the material while printing, which is not possible with manual primer application. The PR-200 available to [ UJF-3042MkII EX ] can be used on resin, glass and metal materials without affecting their texture and improve the ink bonding to the material originally the surface coated. Patent number / JPN: 5817059 USA: US9,132,685 B2

2. White ink making more effective expression of full color print

The white ink with high opacity can enhances more vivid expression of full color to print together on a deep color or a transparent material as the base. Plus, max. 2 bottles of white ink can be attached to the printer to realize the high density white print in a short time with more opacity.

3. Clear ink print to represent the texture and to enhance design

With the [Glossy finish] for bright glossiness and the [Matt effect] for muted frosting, [Embossed print] by partial multiple layers, the high value-added print is available by the utilization of clear ink. It adds the glossiness, 3-D appearance, texture and premium feel. Print images with MCC 129 types of texture library are ready By installation of Mimaki RIP software 「RasterLink6」, the [ ARTISTA UV Texture Library ] of the equipment of 129 types of texture pattern will be registered to your PC as the swatch in Adobe Illustrator. Various textures are ready starting the [ BASIC ] pattern for elemental expression and the [ ARTISTIC ] pattern with floral-motif and symbols, the [ MODERN ] with visual effect. Expression of those textures with the clear ink can realize the print for more elaborated design. ARTISTA UV Texture Library Texture List ARTISTA UV Texture Library Texture List [ARTISTA UV Texture Library] (129types) * BASIC (44 types) : Basic pattern * ARTISTIC (45 types) : Patterns give a design effect with floral-motif and symbols * MODERN (40 types) : Patterns give a visual effect

4. Advanced mechanical structure assists value-added print products

Table-driven printing delivers superior quality image Table-driven printing To reduce printer unit vibration, the print table moves vertical direction during printing without moving the upper unit of the printer. In addition, to achieve higher positional accuracy, two ball screws are installed on both sides of the table to assist table movement. The precise droplet placement reduces-gloss banding issues and enables creating more valuable print products. In addition, the noise level of this model is remarkably reduced compared to the conventional model; thus, this printer can be installed in an office. Direct printing on an object up to 153 mm thick The printable object can be as thick as 153 mm (*1). Moreover, the advanced sensor detects even a transparent object (*2). The new model accepts a range of materials with simple set-up steps. *1: To utilize this feature, spacers are required depending on the thickness of the object. The spacer is one of accessories of UJF-3042MkII EX. *2: Depending on object size or form, the sensor may not detect the object properly.

5. High-performance UV-curable inks expand the range of applications

Flexible LUS-120 ink can print on soft materials The flexible LUS-120 ink stretches up to 170% and delivers beautiful and durable print results on soft materials including leather or polyurethane. Flexible LUS-150 ink has versatile adhesion capability on to various materials The LUS-150 ink stretches up to 150% and delivers vibrant color representation. In addition to its use on soft materials, this ink adheres very well to rigid materials such as glass or acrylic. Examples of ideal applications are indoor signs or trophies. Rigid LH-100 ink is highly scratch resistant The LH-100 ink features high scratch-resistant, is chemically resistant, and has excellent color reproducibility. Ideal applications are smartphone cases, key fobs made of resins or plastics.

6. Mimaki's unique techniques provides more beautiful print

Mimaki Expand Color improves color representation The new input profile, Mimaki Expand Color, is added to Mimaki genuine RIP software, RasterLink6. This profile enables representing more vibrant solid colors and brighter skin tones than a conventional input profile and provide more attractive print results with high-contrast color shades; bright parts are brighter and dark parts are darker. Effectiveness of Mimaki Expand Color, a new input profile of RasterLink6 Effectiveness of Mimaki Expand Color, a new input profile of RasterLink6 Mimaki Advanced pass System 4 (MAPS4) minimizes banding and uneven color printing MAPS4 has been newly added to the UJF-3042MkII EX models. Generally, swath boundaries are straight lines. Therefore, a slight misalignment between boundaries causes banding or uneven color printing. MAPS4 reduces banding and uneven color printing with blurred boundaries similar to gradation printing. Illustration of MAPS4 MAPS4 applied MAPS4 applied Banding and uneven color printing are reduced by scattering swath boundaries. Beautiful print image is obtained. No MAPS4 No MAPS4 Bandings appear on swath boundaries. Print quality is remarkably degraded because banding is recognizable on each boundary. Waveform control and variable dot printing achieve smooth and quality print image Each ink color has its own specific gravity and viscosity. To achieve a precise placement of ink droplets onto the media, Mimaki has designed an optimum waveform control technique that allows the printhead to jet each ink color at an optimum angle, maintaining excellent ink droplet circularity. Thanks to precise ink droplet landing, three different droplet sizes (5 pl to 22 pl *) are properly used for providing optimum print results. * The maximum droplet size is 27 pl when using white high-dense mode.

7. Maintenance functions ensure worry-free operation

NCU automatically detects and recovers clogged nozzles Clogged nozzles are detected automatically by monitoring ink droplets with sensors. When clogged nozzles are located, these are automatically cleaned, reducing waste printing. Nozzles are checked per transfer file. * NCU is a standard feature of UJF-6042MkII and UJF-3042MkII EX, and an optional feature of UJF-3042MkII. NRS for maintaining productivity If the clogged nozzles are not recovered after cleaning through the NCU function, the NRS selects substitute nozzles and then restarts printing. This is a significant novelty, since previously, when nozzle cleaning fails, the printhead has to be repaired by a technician, and the printing operation ceases until the printhead is repaired. The NRS* allows the printer to continue printing without interruption by using non-defective nozzles as substitutes for defective nozzles until the technician arrives. (*) * NRS may not be activated depending on print modes. NCU, NRS Fig. 1: NCU and NRS *Click to view larger image. Mimaki Circulation Technology (MCT) minimizes downtime MCT is used in the ink tank and channel. The white ink is circulated at regular intervals to prevent pigment sedimentation that leads to malfunctions of the printhead.
