How to integrate UV LED curing units in printing machines for perfect polymerisation
The today’s integration of a UV LED curing unit into printing machines is more like a trial and error procedure than a scientific work. The knowledge of the optical characteristic related to UV power and illumination time to the substrate are important for the design. Hapa shows and supports engineering methods for perfect designs of UV LED units for their UV curing inks. This process is important to realize low migration applications and also adhesion on different substrates.
