• Up to 20,000 sheets/hr in 4-over-4 production as well

  • Fast makeready and high process automation

  • Extensive inline quality control

  • Equally cost-effective for long and short runs

At the beginning of the month, Raff & Wurzel Druck from Riederich in the south-west of Germany ordered a new high-performance press from the Rapida 106 X series made by Koenig & Bauer. It is scheduled to enter production in the late summer. The company has celebrated a very successful first business year since its relaunch in February 2021, and views the investment as vital preparation for further growth and future market challenges.

The eight-colour perfector press with additional inline coater is replacing a six-year-old sheetfed offset press in a similar configuration for the 3b medium format. It also defines new benchmarks in terms of performance – with production speeds up to 20,000 sheets per hour, and this in perfecting mode as well, with significantly more automation, and with extensive inline quality control features. The resulting benefits will give Raff & Wurzel the major technological advance it desires.

Increased print capacity

Managing director Thomas Uehling is already looking forward to the arrival of the new press: “Our production has been running at its limits over the past months. The new press will give us capacity reserves – including ones for additional jobs.” Uehling’s priorities are maximum availability, significant advances in process optimisation, the highest possible quality and a similarly high level of production reliability.

Accordingly, QualiTronic PDFCheck with its functions for colour control, sheet inspection and comparison of the printed image with a pre-press PDF, DriveTronic SPC and CleanTronic Synchro for fast job changes, and the LogoTronic performance package with PressProduction and OEE reports, are among the most important items on a long list of press features. On this basis, offset printing becomes profitable for run lengths involving as few as 300 sheets.

Even short runs are expected to be produced at high speed in perfecting mode. Thomas Uehling: “If this allows us to handle three extra projects every day, that will be a great help.” Christopher Sommer adds: “At the same time, the press will close a few gaps and enable us and our customers to address new market segments.” Peter Dankesreiter is equally pragmatic in his assessment: “The Rapida will even allow a number of smaller jobs to be handled profitably which would otherwise be assigned to a web press. But it is also ideally positioned between digital and offset printing.”

Focus on ecology

Alongside the quality control systems, which serve to reduce waste and potential customer complaints, further equipment details contribute to environment protection and resource efficiency in the print process. They include the VariDryBlue dryer systems, which recirculate the only partially saturated hot air from the first dryer modules in order to minimise overall energy consumption. Thanks to water cooling, waste heat from the press can be used to heat offices and production spaces. Low-alcohol printing, on the other hand, has meantime practically become the standard in the print industry.
