• Mimaki's unique print-quality management enhances color representation
  - Mimaki Expand Color is preset in RasterLink6 (*5) and it delivers upgraded color representation with more vibrant solid color or brighter skin tones.
  - Mimaki's unique printhead control techniques, including the Mimaki Advanced Pass Ssytem4 (MAPS4), variable dot printing and waveform control, deliver print results of exceptional quality.
  *5: Mimaki genuine RIP software
  
  
• Maintenance functions ensure worry-free print operation
  - Nozzle check unit (NCU) automatically detects clogged nozzles and performs cleaning; moreover, the nozzle recovery system (NRS) uses only good nozzles as substitute if the clogged nozzles are not recovered after cleaning. These functions allow constant printing and reduce waste printing due to defective nozzles.
  - Mimaki circulation technology (MCT) is used in the white-ink tank and channels and it circulates white ink at regular intervals to prevent pigment sedimentation that leads to nozzle malfunction.

Because of the new printhead, with its longer nozzle lines (*1), the print speed of the UJF-3042/6042MkII has been increased by approximately 120 % (*2) more than that of conventional models. The maximum print speed of the UJF-3042MkII is 2.48 m²/h (*3) and UJF-6042MkII is 3.52 m²/h (*4). Moreover, the staggered printhead arrangement (Fig.1) increases productivity by printing process and spot colors simultaneously (*5). In FabLabs or retails stores, the new UJF-3042MkII and UJF-6042MkII models motivate personal customers to create customized items by demonstrating usability and instant print features.

Table-driven printing delivers superior quality image

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. Moreover, the advanced sensor detects even a transparent object (*6). The new model accepts a range of materials with simple set-up steps. 
*6: To utilize this feature, spacers are required depending on the thickness of the object. The spacer is one of accessories of UJF-3042/6042MkII.

Fully covered print table improves the safeness of the printer

Lift-up table cover

The fully covered print table prevents accidents involving operator contact with the printer carriage. It also maintains print quality by reducing dust adhesion.

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 _(*7)

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.
*7: The LUS-150 ink will be loadable in the future.

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.

PR-200 primer increases ink adhesion

The PR-200 primer enhances the ink adhesion. The primer can be applied to the required areas by ink-jetting. This feature retains the texture of the material, which is not possible with manual primer application. The PR-200 can be used on resin, glass and metal materials without affecting their texture.

The clear varnish ink offers valuable new print effects

Mimaki clear control (MCC) has been newly added to the UJF-3042MkII and 6042MkII models. This technique adds a glossy finish on desired areas and a premium appearance to the print. However, clear-ink prints tend to be ruined by dusts adhering to uncured inks. In order to minimize dust adhesion and air bubbles on the print, MCC shortens the ink curing time by processing the clear ink print and UV-light irradiation simultaneously. MCC provides a gorgeous gloss finish and a stylish matte finish. Moreover, an embossed print is available by multiple applications of clear ink on specific areas; it adds a dimensional appearance to the print and enables representing the freshness of food or elaborate designs.

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.

Mimaki Advanced pass System 4 (MAPS4) minimizes banding and uneven color printing

MAPS4 has been newly added to the UJF-3042MkII and 6042MkII 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.

Fig. 2: Illustration of MAPS4

MAPS4 applied  Banding and uneven color printing are reduced by scattering swath boundaries. Beautiful print image is obtained. 

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 (6 pl to 24 pl *8) are properly used for providing optimum print results. 
*8: The maximum droplet size is 30 pl when using white high-dense mode.

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.

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. (*9)
*9: NRS may not be activated depending on print modes.

• 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.

 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.

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.
