Koenig & Bauer’s new high-end Rapida 76

With a printing output of upward to 18,000 sheets per hour, the Rapida 76 is built for speed Photograph K&B

K&B has just released a new generation of the Rapida 76 sheetfed offset printing. The B2 press (standard sheet format 530 x 750 mm; special format 605 x 750 mm) has a high level of automation, a minimal footprint, and summit press speeds of upwards to 18,000 sheets an hour.

Automation functions characterize the Rapida 76 equally an extremely efficient press, with loftier-performance features including DriveTronic dedicated bulldoze components, which eliminate gear systems and provide for both simple treatment and parallel processes during chore changeovers and make-gear up. There are full preset capabilities of all press functions and the ErgoTronic panel with a wall screen. The Rapida 76 has additional decentralized touchscreens for maximum ease of operation.

Highly configurable Rapida 76

For as many dissimilar applications as possible, up to 11 printing and finishing units can be combined to configure a Rapida 76 for specific production needs. That could hateful a ten-color printing with an automatically convertible perfecting unit for 5 + 5 product – perhaps together with an additional coating belfry to allow printing of covers, for case – or packaging presses with double-coating facilities for the product of pharmaceutical packaging.

Further variants contain raised foundations to suit higher piles with board substrates or various commitment extensions for coating applications. Ink duct dividers can likewise be chosen to enable rainbow printing. Thanks to a comprehensive range of measuring systems and optional facilities for inline sheet inspection, the Rapida 76 can be configured for many special applications, including the production of security documents.

The new press is no less flexible when it comes to compatibility with different ink and coating systems. It handles both conventional and UV inks and coatings with equal ease. Beside IR/gasbag drying systems, various UV, HR-UV and LED-UV systems are also available.

Special K&B features

The Rapida 76 offers unique features that do good users in their daily work only are not yet mutual in about half-format size presses. Inking units that are not required for a particular chore can exist disengaged from the press drive. This reduces roller wear and cuts brand-ready times. When production is to exist resumed, the units concerned are re-engaged at the press of a button.

On the Rapida 76, unbent plates can also be mounted, irrespective of whether an automated or simultaneous plate changing arrangement is in apply. This feature was introduced on the new Thou&B Rapida B1 press in June at the G&B Live virtual demonstrations. Information technology will probable permit even higher automation of the press room if needed.

With simultaneous plate irresolute, all the plates on the Rapida 76 can exist changed in just 45 seconds. In combination with CleanTronic Synchro, the blankets and impression cylinders and the ink rollers – tin be washed parallel to plate changing. This shortens brand-ready times dramatically and leaves much more fourth dimension for actual production. The aforementioned applies to automated coating forme changes.

Wide range of measuring and control systems

Awarding-orientated measuring and control systems contribute to faster make-ready, reduced waste matter, and consistently high and stable print quality. The Rapida 76 can be configured with systems for register measurement and control, color control and sail inspection. All inline systems operate with a common camera, which reduces maintenance requirements and simplifies handling.

The one camera system can be configured to perform upward to three functions – color control, canvas inspection and PDF comparisons Photo K&B

In a full-featured setup, ErgoTronic ICR controls the register by way of a single sheet placed on the console, while QualiTronic ColorControl provides for convenient color aligning. The photographic camera organisation installed after the concluding printing or coating unit or after the last unit before perfecting automatically determines the optical densities. It controls the ink keys without further intervention. Equally an option, the arrangement can be expanded to implement colour control according to grey rest (QualiTronic InstrumentFlight). QualiTronic PDFCheck carries out the inspection of the printed sheets and comparison with the customer'south PDF as the basis for uncompromising quality.

Digital services at the press of a button

Many digital services surrounding the Rapida 76 help reduce unplanned downtimes, facilitate convenient and bulwark-free maintenance of the printing, and permit bearding comparisons of important performance parameters with other presses in identical configurations. The options range from PressCall for optimization of communication with remote maintenance engineers and VisualPressSupport to enable a meliorate clarification of the reason for a remote maintenance call. The remote support functions use photos (with all-encompassing commenting functions), texts, videos, and sound, via Operation Reports and Press Inspection Reports, through to the first instances of predictive services based on bogus intelligence methods.

In this context, the Customer Customs is a central point of contact bringing all service offers together nether i roof. Users and the manufacturer have access to an identical information database, meaning that they are all on the aforementioned folio.

As you join united states today from India and elsewhere, we have a favour to ask.
