HEIDELBERG , GERMANY—  Gallus  developed UV inkjet printing to enable the production of certified food-compliant labels with the Gallus Labelfire. The low migration version of the Gallus Labelfire is designed to produce food-compliant packaging in accordance with Government food regulations . Gallus developed the Labelfire UVLM ink series, which is suitable for food contact packaging. The UV curing technology of Labelfire was also further optimized to improve the migration properties of the ink film. Directly after printing, the substrate is fed into a dryer with an inert chamber, which is flooded with nitrogen. The extensive exclusion of oxygen leads to optimized curing of the inks. An optional UV booster enhances curing of the Labelfire UVLM inks at higher printing speeds even at maximum production speed.
