UV Inkjet Printing on Food Packaging: State of Art and Outlook

• Inkjet printing on packaging = answer to packaging trends

• UV LM inkjet ink formulation  low viscosity for jetting

• Thereby requires full conceptual development of LM ink concept

• Monomers and photo-initiators need to be LM ink specific designed for combination of low viscosity and high curing degree

• Dedicated LM inkjet ink technology can result in low migration levels, including direct print on food packaging

• Highly reactive monomer is key driver to full curing

• Diffusion-hindered PI system key to curing speed (UV LED curing) and low migration of PI‟s
