The KBA RotaJET 76 on display at Drupa will be operating in conjunction with a SigmaLine digital production system from Müller Martini, a solution for overall production control which has already been installed with numerous users worldwide. SigmaLine is here configured with the variable-format section folder module SigmaFolder and a Primera Digital saddle stitcher system, enabling digitally printed magazines and advertising brochures to be folded and stitched inline. SigmaLine is controlled through the smart data and process management system Connex, which ensures consistent integration between the printing press and the finishing equipment. Thanks to the modular system design and the broad spectrum of finishing options, SigmaLine can be tailored for both softcover and hardcover book production, as well as for a diversity of stitched products.
Turning to sheetfed offset users, the responsible head of marketing Jürgen Veil announced new press generations to be unveiled at the show, alongside ground-breaking technology innovations in all format classes.
New Rapida 145 defines new benchmarks for large format
As the established market leader, KBA has chosen Drupa as a fitting occasion to redefine the benchmarks for offset printing in large formats. The latest generation of large-format Rapidas is to celebrate its official market premiere in the form of a plinth-mounted six-colour Rapida 145 with new coater, triple-length extended delivery and automated pile logistics. The maximum production speed of the 1050 x 1450mm (41.34 x 57in) Rapida 145 is 17,000sph in straight printing with the high-speed package and 15,000sph in perfecting mode with the new three-drum perfecting unit. Many of the automation modules of the makeready world champion press Rapida 106 are now also available to large format users. The press to be seen at Drupa, for example, features the sidelay-free infeed DriveTronic SIS and DriveTronic SPC direct drives for fast, simultaneous plate changing. The CleanTronic Synchro system (two washing beams) for simultaneous washing of ink rollers, blankets and impression cylinders parallel to plate changing, a new programme for extremely fast inking unit washing (CleanTronic ReInk) and further parallel makeready processes contribute to significantly higher net production output compared to the predecessor series and presses from other manufacturers. The same can be said of the new coater with simultaneous coating forme changing (DriveTronic SFC) and of the fast, one-man replacement of the exchangeable anilox roller sleeves (AniSleeve). The high production speed of 17,000sph is made possible not least by the new AirTronic delivery with high-level Venturi sheet guiding, dynamic sheet brake and console-based preset capabilities, and by a new blade chamber for the coating system (HighFlow Chamber). Convenient operation is guaranteed at the new ErgoTronic console with wall screen, picture-in-picture function and integrated colour measurement and control system (QualiTronic ColorControl) for quality monitoring. In addition, the new large-format Rapida presses feature inline register control (QualiTronic ICR), and with QualiTronic PDF it is possible to perform an inline comparison between the print result and the original PDF file. The energy-saving KBA VariDryBLUE dryers which were already offered to large format users are to be made available also for medium-format presses in the future.
Digital joins offset: Rapida 105 with inkjet printing system
With the Rapida 105, KBA will also be presenting a completely new medium-format series in Düsseldorf. The press was unveiled to the public at the All in Print China fair in Shanghai last November. The high-level delivery is immediate indication that the new Rapida 105 is based on the same platform as the high-end Rapida 106 press. The range of automation options has been extended compared to the predecessor model. After positive experience with the presses delivered over the past three months, the maximum production speed for presses incorporating the high-speed package is to be raised to 17,000sph (standard: 16,500sph) with effect from Drupa. The Rapida 105 is now also available in a four-back-four perfector configuration, with a perfecting unit based on the modern technology of the Rapida 106. The new Rapida 105 thus packs all the features expected of a modern commercial press placed under the banner: “Designed for Performance”.
