Mimaki UJF 3042(HG) and 6042 - Print Module and Special Inks

Resolutions

  360* 540* 720* 1080* 1440*
300
600
900
1200
300-Fix
600-Fix
900-Fix
1200-Fix

  Info

Resolutions of 300 dpi in one direction are not implemented in the driver, as they do not provide sufficient ink density. Additionally, there is no bidirectional printing due to hardware limitations.
For more explanations about resolutions, see the chapter dedicated to "Special Inks and Effects".

 

Modes

Here is the list of modes supported by the Mimaki UJF printer. Please note that some modes may not be available depending on your specific model.

Mode Use
CMYK Colors only
CMYKcm Cyan, Magenta, Yellow, Black, light cyan, light magenta
White + CMYK White under colors in one pass
CMYK + White White over colors in one pass
Primer + CMYK Primer under colors in one pass
CMYK + Clear Coat Clear Coat over colors in one pass
White only White only (1 or 2 channels)
Primer only Primer only
Clear Coat only Varnish only

 

Qualities

Qualities depend on the selected resolution, media, and mode. Some combinations may not support compatible qualities, which can vary with each firmware and printer. Qualities are structured as follows:

<Number of passes> <Uni-Directional> <Normal Speed/High Speed> 

 

Special Inks and Effects

Special effects are created by layering different jobs configured to use primer, white, color, or varnish (Clear Coat).

  Warning

Unlike some other CalderaRIP drivers, each layer must be sent as a separate job (except for White + CMYK, which can be sent in one pass).
We strongly recommend saving each layer configuration as a preset. This will prevent the need to enable and disable settings each time you print.

 

How to configure special inks?

  Info

The Overplotting mode (undercoat or overcoat) can be configured in Printer Settings > Printer tab.

  1. Ink selection can be made first by choosing a color mode in the Print Module Interface.
  2. Ensure that the corresponding tab(s) are enabled in the Page Setup window, while other special ink tabs should be disabled.
  3. In the selected tab, configure the method (e.g., Full Page Coverage, Generate from CMYK Data) and source for your special ink  to achieve selective printing for that layer.
  4. Save this configuration as a preset.
  5. (Optional) For UV-only passes (scanning with UV ON and no printing), change the "Action" in Printer Settings > Printer tab from "Print and UV" to "UV Only".

  Info

To achieve both matte and glossy varnish finishes, you must use two different media, each with its own parameters (UV lamps) configured for the respective finish. 
Since both finishes utilize the same resolution and mode (Clear Coat only), they will share the same media parameters unless you specify two different media.

 

Achieving Optimal Rendering with All Inks (Primer, Colors, Glossy Finish)

This has been tested with LH-100, CL-100, and PR-100 inksets. Because all layers are defined in separate jobs, you can adjust the resolutions to optimal settings for each layer.

 

Primer Application

  • Resolution: 720x900 (Variable Drop; do not use the -Fix option)
  • Mode: Primer only
  • Quality: 24 passes
  • Maximum Density: 30% (full coverage should not exceed this)
  • UV Lamps (Media Parameters): 120%
     

  Warning

A primer layer is recommended for glossy media and metal surfaces.

 

Colors Application

You can choose any quality that meets your requirements for speed and performance; however, Mimaki recommends the following modes for optimal results:

  • 720x600: 16 passes
  • 720x900: 24 passes
  • 720x1200: 32 passes
  • 1440x1200: 16 passes
  • 1440x1200: 32 passes
  • 1800x1800: 24 passes
  • 720x600-Fix (Normal Drop): 8 passes

 

Varnish Application

To ensure good adhesion for glossy varnish, first print a layer of matte varnish where you want the glossy finish. For the glossy finish, follow these steps to adjust irradiation and ensure proper flattening and hardening:

General Guidelines

  • Print with minimal or no irradiation initially to allow the varnish to flatten.
  • Fix with slight irradiation to avoid wrinkles.
  • Harden with additional irradiation.

Case A: Using 720x600

  • 1st Layer: Matte varnish at 8 or 16 pass, UV at 100%
  • 2nd Layer: Glossy varnish at 4 or 8 pass with high ink density (≥ 70%), UV lamps at 0 or 10% max
  • 3rd Layer: UV irradiation to fix at 8 pass, UV lamps at 20-30% max to avoid wrinkles
  • 4th Layer: UV irradiation to harden at 8 pass, UV irradiation at 100%

Case B: Using 720x900

  • 1st Layer: Matte varnish at 12 or 24 pass
  • 2nd Layer: Glossy varnish at 6 or 12 pass
  • 3rd Layer: UV irradiation to fix at 12 pass
  • 4th Layer: UV irradiation to harden at 12 pass
