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

The SICURA Jet D2 K is an UV-curable and pigment-based deep black ink designed for industrial inkjet printing specialized for sharp edges and high resolutions in the area of coding & marking. The SICURA Jet D2 K is targeted at a wide range of label and packaging applications.

The SICURA Jet D2 K 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 ink is able to generate low droplet volumes at high frequencies.

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

The SICURA Jet D2 K 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 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 D2 K ink is designed for single-pass inkjet printing with piezo drop-on-demand printheads including printheads from Kyocera, Fuji Samba, Epson or Ricoh (MH5220) which low viscosity ink. 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].
