SICURA Jet G4
High Performance single-pass UV-curable inkjet inks for drop-on-demand inkjet printing
The SICURA Jet G4 product line is an UV-curable and pigment-based ink set specifically designed for industrial inkjet printing on flexible applications, including direct-to-shape printing, laminated tubes, packaging and label printing.
The standard set includes cyan, magenta, yellow, black (CMYK), white and flushing solution. It is targeted for both large width full color printing and single color coding & marking. Additional colors tailored to extend the color gamut (e.g. OGV) and spot colors are available upon request.
The SICURA Jet G4 has 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). The inks are able to generate low droplet volumes at high frequencies.
This inkjet series can be used for printing on thin and flexible materials or in direct-to-object printing projects.
The SICURA Jet G4 is 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.
This ink series can be customized and adapted to end-user applications. If needed, Siegwerk can tailor ink properties (e.g. viscosity & adhesion), film properties (e.g. color gamut & fastness) 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 G4 ink set is 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].
Key benefits
| CHARACTERISTIC | BENEFIT |
|---|---|
