High Performance single-pass UV-curable white inkjet ink for drop-on-demand inkjet printing

The SICURA Jet E1 White is an UV-curable and pigment-based white ink designed for industrial inkjet printing on multiple applications, including decorative printing, direct-to-shape printing, coding & marking, packaging and label printing.

The SICURA Jet E1 White is a white ink for pre-printing to be over-printed with SICURA Jet E1 cyan, magenta, yellow, black (CMYK) as well as Whites for post-printing or E1 Whites for printing large areas. The ink has a very high opacity and a neutral white color.

The SICURA Jet E1 White has been developed for single-pass, piezo, drop-on- demand industrial inkjet printing at high resolution using printheads from Epson.

This 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 E1 White 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) 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 E1 White is designed for single-pass inkjet printing with piezo drop-on-demand printheads including printheads from Epson which require medium viscosity inks. It is NOT recommended for thermal inkjet, continuous inkjet of any kind or any other print technology systems.
