German specialist security printer Trautwein has invested in three Domino K600i colour piezo inkjet printheads to print high quality digital applications such as security seals, codes, labels and document overlays. Installed across the company’s existing special web production line, at its facility in Herne, Germany, the UV curable 600dpi printheads were chosen due to their capability of applying high quality variable data overprinting onto a wide range of substrates at very high production speeds.
Oliver Thiele, general manager at Trautwein, explains: “We print both variable and static data onto a huge variety of different substrates, some of which can be extremely thin and delicate, while others can comprise several different ‘security’ layers. Therefore, it was essential that we found a solution that would deliver the highest quality print onto a wide range of delicate materials without impacting on our production output.”
The native 600dpi print resolution of the K600i, with its three or four greyscales and high production speeds of 50-75m/min was also a key benefit for Trautwein. It accommodates different print widths by stitching heads across web machines; having invested in three printheads, Trautwein is now able to print up to 333mm.
