SICURA Jet G2 Whites

High performance single-pass UV-curable white inkjet inks for drop-on-demand inkjet printing.

The SICURA Jet G2 White product line are UV-curable and pigment-based white inks designed for industrial inkjet printing on multiple applications, including decorative printing, direct-to-shape printing, coding & marking, packaging and label printing.

The SICURA Jet G2 White set includes Whites for pre-printing to be over-printed with SICURA Jet G2 cyan, magenta, yellow, black (CMYK) as well as Whites for post- printing or Whites for printing large areas. The inks have a very high opacity and a neutral white color.

The SICURA Jet G2 Whites have been developed for single-pass, piezo, drop-on- demand industrial inkjet printing at high resolution using printheads from Kyocera, Fuji Samba, Epson or Ricoh (MH5220).

These inks can be used for printing on rigid as well as thin and flexible materials or in direct-to-object printing projects.

The SICURA Jet G2 Whites are designed for extremely good adhesion on many types of substrates including plastic labels or foils (e.g. PP, PVC, PS) and aluminum based substrates. For many of these substrates pre-treatments (corona, plasma or flame) will have a positive effect on the adhesion of the ink.

These inks can be customized and adapted to end-user applications. If needed, Siegwerk can tailor ink properties (e.g. viscosity & adhesion) and even address further special customer requirements. Depending on the application, Siegwerk can also advise on suitable primers or overprint varnishes (OPV’s).

Field of use

The SICURA Jet G2 Whites are designed for single-pass inkjet printing with piezo drop-on- demand printheads including printheads from Kyocera, Fuji Samba, Epson or Ricoh (MH5220) which require low viscosity inks. 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].
