SICURA NutriJet GLM Primer

High Performance singe-pass UV-curable Low Migration Primer for drop-on-demand inkjet printing

The SICURA NutriJet GLM Primer is an UV-curable high performance jettable Primer solution designed for industrial inkjet printing on multiple applications, including decorative printing, direct-to-shape printing, packaging and label printing. 

The SICURA NutriJet GLM Primer has been developed for single-pass, piezo, drop-on-demand industrial inkjet printing at high resolution using printheads from Kyocera, Fuji Samba, Ricoh (MH5220) and Epson. 

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

The SICURA NutriJet GLM Primer is designed to improve the adhesion and the spreading of the Siegwerk SICURA NutriJet GLM inks on challenging substrates. The pinning and curing of both the primer and the inks have to be adjusted depending on the printing parameters. 

The SICURA NutriJet GLM Primer is particularly well suited for applications with high product safety and regulations (PS&R) demands such as food or pharma packaging. When needed, Siegwerk can support risk assessments and real case migration and fastness testing for PS&R sensitive applications - verifying system compliance. 

This Primer can be customized and adapted to end-user applications. If needed, Siegwerk can tailor Primer 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 Primeres (OPV’s). 

Field of use

The SICURA NutriJet GLM Primer is designed for single-pass inkjet printing with piezo drop-on-demand printheads including printheads from Kyocera, Fuji Samba, Ricoh (MH5220) and Epson which require low viscosity inks. It is NOT recommended for thermal inkjet, continuous inkjet of any kind or any other print technology systems.

Key benefits


Jetting performance 

The product is formulated for high performance piezo drop-on-demand printheads requiring low ink viscosity. Well suited for high resolution jetting at high frequencies. Good storage stability. 

Dried film performance 

Excellent adhesion and flexibility on a broad range of substrates. Improves the laydown and spreading of Siegwerk inks, which are jetted on top of the product. 

Shelf life 

Long shelf life (12 months from production date). 

Product Safety and Regulations 

Low-migration capable. Migration-sensitive applications possible, including pharma, food and hygiene packaging. Risk assessment and real case migration testing need to be carried out individually. 

Functional Specifications

  • Single-pass wet-in-wet printing or printing using intercolor pinning 
  • Curing with bulbs and/or UV LED; curing dose needs to be optimized in function of migration limits 
  • Printing on a broad range of plastic materials and many more (suited for migration-sensitive applications) 
  • Product parameters suited for jetting with industrial piezo print heads requiring low viscosity range 
  • Very good storage stability, long shelf life
  • Good jetting reliability and low print head maintenance need 
  • Suited for binary print mode (including large drop size) 

Note: the print conditions depend upon the choice of substrate, print mode, print resolution, print speed, printhead, throwing distance, etc. 

Shelf life & storage conditions

  • Shelf life is 12 months from production date when stored under recommended condition o Storage properly closed in Siegwerk bottles/cans
