KBA Unveils RotaJET 76 Inkjet Web Press

February 11, 2013

As one of the leading press manufacturers, KBA will naturally pursue the topics of print quality and substrate flexibility further, and plans to bring high-speed inkjet printing as close as possible to offset. The medium-term objective is maximum flexibility for the users, enabling them to serve not just a limited market segment, but rather the full spectrum of today's print products with the RotaJET 76. This will involve also continued improvements with regard to process costs, full page-to-page content variability and the impressive format flexibility. The unique combination of capabilities embodied by the RotaJET make it an especially attractive alternative to other analogue and digital sheet printing systems for many applications.

...with interesting options for professionals
The image of a digital print system built for professionals by professionals is upheld by the availability of a web remoistening unit and a coater. The automatic reelstand KBA Pastoline is another interesting option which is not available in this form from any competitor. With the facility for flying changes, the autosplicer lends a considerable boost to performance and can also be integrated into an automated paper logistics set-up with KBA Patras. High-speed inkjet printing with the RotaJET is in this way lifted to previously unknown levels of productivity.

High-speed inkjet with a small footprint

The KBA team was initially none too happy with the very limited space provided at the Hunkeler Innovationdays. As a newcomer, the company had been allocated an area of just 91 m² for its 25-tonne high-speed press (3,000 A4 pages/min.; 85 million A4 pages/month). And that for the press with the greatest output at the show in Lucerne. On the other hand, the small stand did underline the compact design of the RotaJET. Thanks to an intelligent web lead, the press and rewinder are together just 10.5 m long and 6 m wide. It would not have been possible to install other 4/4 presses of this performance class in such a small space.

For its entry into the digital print market, KBA will at first be focussing on the target segments books, direct mailing, manuals, advertising, newsletters and newspapers. The live demonstrations of book production and a daily exhibition newspaper with original content from the “Neue Luzerner Zeitung” were among the highlights of the show. The book sections were produced reel-to-reel on the RotaJET and then combined with ready-printed offset covers on a Hunkeler finishing line. The finishing of the exhibition newspaper was also handled by post-press systems from Hunkeler.

The packaging and security printing segments are to be addressed later. One field which KBA excludes for the RotaJET, however, is the transaction and transpromo market which has evolved in the electronic business world. Printers interested in the new possibilities for digital print are offered break-even calculations and production scheduling analyses to assist their investment decision.
