Busting the myth.

Even though flexo presses offer considerably more in the way of flexibility, they also might lead to losses in changeover times, pressure stability, and varied performance on-press. There are other considerations like rail systems and drop-in variants. With a host of variables worth monitoring, choosing the right press is ever-more critical. Making the correct choice can launch a printing business, however.

A recent study from Heidelberg-Gallus sees process changes as a macro trend, with the flexo manufacturer capable of delivering the shortest possible changes leading to the greatest productivity of the machine. The study, which focused on the Heidelberg-Gallus Labelmaster, assumed two process changes per shift. The customized configuration of the Labelmaster led to annual savings of 38,400 euros compared to a rail system, or 76,800 euros compared to a drop-in variant.

In the case of the Labelmaster Advanced, the press does not have to be switched off during the process change, as this occurs while the machine is running. Other factors can also influence the bottom line. In the case of the Labelmaster, it takes 1.4 meters for the web to travel from printing unit to printing unit. According to Heidelberg-Gallus, this is made possible by arranging all the essential processes on the primary level, whereby no change to another level is necessary. The use of a screen printing unit on a rail, for example, causes an additional path of 4-6 meters. The arrangement of the printing units on the primary level, however, saves material, time and costs during setup...
