SICURA Jet Matt Varnish
High Performance single-pass UV-curable matt varnish for drop-on-demand inkjet printing
The SICURA Jet Matt 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 product gives a matt appearance to the final application and it can either be used on certain areas only or on the full surface.
The SICURA Jet Matt 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. Printheads with big nozzles and recirculation up to the nozzle plate are recommended for this product.
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 Matt Varnish is designed for extremely good adhesion on the Siegwerk SICURA Jet ink series.
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 Matt 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.
