On the one hand there are short jobs, a raft of different orders and high quality products, and other the other hand the focus is on high-volume print runs – customer demands placed on commercial printers are becoming ever more versatile and challenging. Koenig & Bauer has been successfully tackling both of these developments for years. Stefan Segger, sales director Digital & Web Solutions said, ‚We are in constant communication with our customers. On the one hand we develop new products with our partners, and on the other hand we are proactively represented on the market with new innovations.‘
The new UV coater from Koenig & Bauer offers production speeds of up to 60 000rph, high automation, simple and self-explanatory operation, the stability of a printing unit, automatic cleaning at the push of a button and anilox roller change within a few minutes. Whether for the full-solid finishing of covers or as spot coating for the partial finishing of printed images, the coating unit is already being used very successfully by customers. A compact UV dryer is integrated into the superstructure after the coating unit to enable the widest possible range of paper substrates to be processed. The UV coater processes substrates with a grammage of between 60 and 250gsm. Between 2 and 5gsm of coating is applied depending on the anilox roller.
Intelligent, patented copy control in the quarterfold makes for a trouble-free folding sequence. Production conditions are therefore always consistent irrespective of operator skill. Copies are slowed effectively and with a minimum of abrasion, and aligned in the direction of fold during deceleration. The automatic copy control system is self-adjusting and exceptionally reliable regardless of production speed and copy thickness. As a result folding is consistently accurate, even during changes in press speed. Stefan Segger added, ‚We continue to be very successful in the market and expect investments to be made this year. Our presses are known for their quality. With our know-how we have worked on many new developments for our commercial presses.‘
The microporous patented turner bars are one of the many proven features that are unique to Koenig & Bauer. They no longer need to be set for different ribbon widths, and operate reliably with a minimal air cushion and superior ribbon guides. A modular design and dedicated drives throughout allow the superstructure to be customised for specific production scenarios. The short and stable web lead allows a more even web tension.
