As inkjet printing progresses, becoming faster and more reliable, regulatory questions like food-contact (Swiss Ordinance, etc.) and health and safety in décor applications (RAL for wallpaper, etc.) play an increasingly important role. This is where UV-curable inks often reach their limits, as their composition of reactive chemistry is often not compliant with health and safety requirements.
Water-based inks can solve this challenge, with a similar application process as UV-curable inks, but without the non-compliant materials. Water-based inks are comprised of binders, dyes
