Gallus shows off next-gen press technology

The world premiere of the Gallus DCS 340 took place during the September 23-25 event. Read more about the new digital label production system here.

The event also showcased the Gallus ECS 340 press with a new direct matrix stripper. Gallus said the functionality of the matrix stripper on the ECS 340 represents a ‘masterpiece of mechatronics’ by its development engineers.

Direct matrix stripping systems have already brought a number of advantages over standard matrix strippers, Gallus noted, with a path roller to guide and support the matrix over just a short distance resulting in far fewer matrix tears and delivering greater process reliability. Complex die-cutting formes – with recessed edges, for example – remain problematic, however, it said.

The new Gallus matrix stripper was developed specifically for matrix removal with highly complex die lines at maximum speeds and enables a stable matrix removal process at all times.

Another development on show was the new RCS 430, with event attendees offered the opportunity to get an idea of what the press will be like.

For the first time since its market launch, the Gallus RCS is being completely revamped. The machine system is being equipped with a state-of-the-art control platform so as to be ready for future market requirements and advances in technology. This control platform is already in use with the Gallus ECS 340 and Gallus EM S machine systems. Gallus said having a common control platform simplifies the training of press operators and means staff can easily be assigned to different machine systems as they are already familiar with the user interface. Many of the spare parts for different machine types are also the same, which makes servicing work more straightforward.

Furthermore, various technical adjustments have been made to the hardware based on Gallus RCS users’ feedback and experiences. Examples include improvements to web transport, a higher register accuracy and optimized inking units in the offset printing unit.

On the RCS 330, a new combination printing process to create metal relief effects was shown. This involves applying the print image using rotary screen printing with a metal foil then laminated onto the screen print. The special feature of metallic doming is that it enables users to apply a metal relief effect on transparent self-adhesive materials or tube laminates.

The Gallus Screeny A-Line was also shown, while developments to the Gallus Customer Services program were also detailed. This included availability of the Twinlock printing cylinder coating and three different high-quality doctor blade types for all Gallus presses.
