SICURA Jet DP2 Varnish
High performance single-pass UV-curable protective varnish for drop-on-demand inkjet printing.
The SICURA Jet DP2 Varnish is an UV-curable high performance jettable protective overprint varnish solution designed for industrial inkjet printing on multiple applications, including decorative printing, direct-to-shape printing, packaging and label printing.
The SICURA Jet DP2 Varnish has been developed for single-pass, piezo, drop-on-demand industrial inkjet printing at high resolution using printheads from Konica Minolta, Ricoh, Seiko, Toshiba or Xaar.
This varnish can be used for printing on rigid as well as thin and flexible materials or in direct-to-object printing projects.
The SICURA Jet DP2 Varnish is designed for extremely good adhesion on the Siegwerk SICURA Jet DP2 ink series. It provides an excellent scratch resistance and protects the ink from external factors.
This product can be customized and adapted to end-user applications. If needed, Siegwerk can tailor varnish properties (e.g. viscosity & adhesion) and even address further special customer requirements. Depending on the application, Siegwerk can also advise on suitable primers.
Field of use
The SICURA Jet DP2 Varnish is designed for single-pass inkjet printing with piezo drop-on-demand printheads including printheads from Konica Minolta, Ricoh, Seiko, Toshiba or Xaar which require regular viscosity inks/varnishes/primers. It is NOT recommended for thermal inkjet, continuous inkjet of any kind or any other print technology systems. In any case of uncertainty, please contact our application technology experts via [email protected].
