RotaJET for Packaging Printing
The trend towards ever greater diversification in the field of consumer goods poses significant challenges for brands and converters. Flying job changes enable highly efficient production of shorter runs, which also allow for personalised and special interest packaging. On the Koenig & Bauer RotaJET, the question of food safety is addressed not just in terms of the inks and other fluids, but for the press as a whole. Accordingly, it is also available in an optional version that meets H1 requirements.
