Duma Druck embraces digital finishing with Tecnau

Wednesday 07. December 2022 - The German company installed a Tecnau Stack 2328 Cut & Stack solution with automated on-the-fly application change capabilities inline to a Xeikon SX30000 press for graphic arts applications on a broad range of print substrates and formats.

Until 2021, Duma Druck GmbH, based in Wolfschlugen, Germany, had used offset printing almost exclusively, upgrading their printer base several times to more than 20 units. But changing market demands and new business possibilities drove the company to take the next step in production digital printing and finishing. For the task, Duma Druck Managing Directors, Frank Illi and Volker Lück, invested in a Tecnau Stack 2328 automated cut and stack solution inline to a Xeikon SX30000 press specifically designed for high-quality and demanding print applications.
For Duma Druck an important reason to go with the Tecnau cut and stack solution was the overall level of automation. The Stack 2328 system offers an automatic, on-the-fly size change option triggered by a datamatrix code printed on the paper web. This fully automated feature allows switching between format lengths without stopping the printer or requiring any operator intervention on the finishing side.
The Stack 2328 is configured with a dual rotary technology for precisely cutting full-bleed color printed applications with a maximum length up to 710 mm (28″) and stacking them with offset separation on an exit conveyor. “We found that purchasing a roll to cut and stack Tecnau solution with a Xeikon press was the right thing to do, as this combination offers a great deal of flexibility” commented Volker Lück, Managing Director at Duma Druck.
“While the long stacker handles sheet-lengths up to 28 inches, there are special applications that require even longer formats. With a special vibrating collecting box, placed instead of the standard exit conveyor, Tecnau provided a solution for banners with a maximum length of 1270 mm (50 inches)” added Stephan Klier, Managing Director at Tecnau Deutschland.
With this new acquisition, the company is now capable of processing a wide range of print substrates with a printer equipped with a 5th inking unit for special or security colors and delivering directly to a finishing line capable of variable on-the fly length changes in 1-, 2-, 3-up impositions.
