The UV-printer contains different types of ink:
- Primer ink
- Gloss/Matt ink
- White ink
- CMYK ink (Cyan, Magenta, Yellow and Key(=Black)
With these types of ink you can print on almost any material as long as it is a 2D-object. For, 3D-objects are not permitted in the UV-printer!
To use specific ink like primer, white and gloss, you'll need to use specific colors in your design (see the table below). For all the other colors you can use the normal CMYK colors in Illustrator.

If the correct settings are not used, the printer won't recognize the swatch.
Before you can print on the UV-printer you need to prepare you file correctly. For this machine we work in Illustrator, because in this program we can create the right swatches that the machine can read. In Illustrator you are free to open any type of file you want. However, it is advisable to work with vector files with a format type like eps. and/or svg. The benefit of working with vector files is that you can easily give a different color to a specific area.
When to use primer
The surface tension of the UV ink should be at least 10 dynes less than the surface energy of your material for proper adhesion of the ink to the material. If this is not the case, you should use primer. Primer is an adhesion promoter. If you don't use primer, adjacent ink drops deposited on the material may not flow freely and join the other ink drops to form one bigger drop. This will cause an image to have a streaky appearance or worse: to be too easily removable.
Dyne is a way to express the amount of surface tension. It is also used to express the amount of surface energy of a material.

By default there's a ruler attached to the table. This helps aligning objects, but also adds an offset to the zero position.
To compensate for this offset, the origin should be set correctly:
Function --> change origin -->
scan = 2.8mm
feed = 5.3mm
the procedure to get into the service menu:
Make sure the printer is turned off.
Press rapidly after each other: Arrow Down - Right - Left - Up - Right - Down - Left. Then press and hold Arrow Left, Down and Right. While holding these buttons down, press the power button.
You should see "Service mode" appear on the LCD screen.
Do not make any changes unless you really know what you're doing!
