Features of Inks

This machine prints using ECO-UV (EUV5) inks and primers. This section explains their respective features.

Features of ECO-UV (EUV5) Inks

This printer uses ECO-UV (EUV5) inks. ECO-UV (EUV5) inks are fixed to the object instantly by ultraviolet light. This makes it possible to print on materials*1 that are difficult to print on using conventional inks.

This printer has one ink type in five colors (cyan, magenta, yellow, black, and white) and a primer.

Features of Primer

The primer is a colorless and transparent coating agent used as an ink base. Ink adhesion may be improved even on materials that are difficult to print on with EUV-5 ink.

Materials that are generally difficult for ink to adhere to include the following.
  • Metal
  • PET (polyethylene terephthalate)
  • PP (polypropylene)
  • PE (polyethylene)
  • Silicone
  • Acrylic
  • Glass

Of these, inks adhere better to metals, PET, acrylics, and glass when a primer is used. However, if the surface is coated or painted with a glass coating, water repellent treatment, stain resistant treatment, or similar, it will be difficult to improve adhesion.

It is difficult to identify any processing or treatment to the surface of a material, even if it seems to be a material for which primer would be effective. Be sure to test print on the actual object to check ink adhesion. Do not proceed with actual printing without first confirming the efficacy of the primer.
