The New Perfecting Dimension in the 50 x 70 Format Class

Speedmaster CD 74 now with perfecting system
Heidelberger Druckmaschinen AG (Heidelberg) will be presenting the Speedmaster CD 74 with optional perfecting system at drupa 2004. This press enables high-quality printing on both sides of the sheet with short changeover times between paper and board and from the straight printing mode to the perfecting mode. Depending on the job mix, an increase in productivity of between 15 and 25 percent over the traditional perfecting presses on the midsize market can be achieved. The target groups for the Speedmaster CD 74 perfecting models are commercial printers handling a wide range of printing stocks, packaging and label printers, and print shops that mainly produce greetings cards or book jackets in perfecting mode. Presses fitted with perfecting technology can make a significant contribution to increasing productivity, particularly in the packaging sector and especially as more and more applications are being printed on the reverse side in this sector, for instance boxes for cosmetics or blister cards.
The three-drum system newly developed for the Speedmaster CD 74 enables even printing stocks up to a maximum thickness of 0.8 millimeter to be processed reliably in perfecting mode. In many cases, with a maximum paper format of 60.5 x 74 centimeters, users can achieve extra productivity when printing multiple-ups or jobs involving special formats . The maximum print speed both in straight and perfecting mode is 15,000 sheets per hour. The Speedmaster CD 74 with a convertible sheet reversing device will be available in four to six-color models, with or without a coating system, and extended delivery. All models are highly versatile all-round presses and support fast setup, simple automated operation and reliability during the production run, even with frequently changing printing stocks of all kind of substrates.
"Medium-sized print shops often only have one press - in the 50 x 70 format range - and therefore demand maximum flexibility, no matter whether for straight or perfecting printing," explains Dr. Klaus Spiegel, member of the Heidelberg Management Board. "The CD 74 with perfecting system now enables us to meet the many different requirements our customers have. This press is a real all-rounder that processes high-quality print products with increasingly diverse printing stocks. Not only that, it can also process board with ease," adds Dr. Spiegel. The new Speedmaster CD 74 perfecting presses will be available in the 53 x 74 centimeters and 60.5 x 74 centimeters format ranges as of summer 2004.
Versatile perfecting press
The tried-and-tested three-drum principle has been complemented on the Speedmaster CD 74 with sheet-reversing device by a raft of new innovations. An ingenious double-sized transfer cylinder has been fitted directly in front of the storage drum. This takes the sheet from the impression cylinder of the printing unit located before the sheet reversing device and guides it towards a double-sized storage drum. The storage drum has all the features of the tried-and-tested Heidelberg sheet reversing device, such as the rotary sucker system which aligns the sheet perfectly. An eccentrically shaped single-sized reversing drum with a pincer gripper bar then guides the sheet in the gripper closure to the following printing unit. The result is a high level of register accuracy, as customers have come to expect on Speedmaster presses with sheet reversing device. The only difference is that this register accuracy is now available for a greatly increased range of printing substrates. The exceptional sheet travel associated with the Speedmaster CD 74 straight-printing models will not be adversely affected by the new perfecting system.
In straight printing mode, the Speedmaster CD 74 perfecting press behaves like its sister model without perfecting system and with the AirTransfer system fitted as standard between the printing units. Heidelberg introduced the new Speedmaster CD 74 with double-sized impression cylinders and AirTransfer system between the printing units at the end of 2000 for printing rigid materials up to 0.8 millimeter thick. The variable AirTransfer system was developed specifically for perfecting printing and it is in this mode that it shows its full flexibility - segments are operated fully automatically and support sheet travel between printing units. What's more, the new generation of high-finish impression cylinder jackets PerfectJacket Plus ensures that the best possible perfecting quality is achieved.
Profitable printing on both sides of the sheet
In comparison with traditional perfecting presses with up to six colors, the increase in productivity on the new Speedmaster CD 74 with a sheet reversing device is directly related to the job mix. The more often heavier printing stocks over 250 gram per square meter are utilized, the more the improvements in productivity become evident. The main reason for this is that these printing substrates, which were previously considered difficult, can now be produced with short setup times (thanks to numerous automated processes), reduced cleaning times and an effortless production run.
The Speedmaster CD 74 allows a pile height of 1.20 meter in the feeder, which greatly reduces the number of interruptions caused by pile changes, especially for thick substrates like carton. All in all, this enables increases in productivity of between 15 and 25 percent.
Printing on both sides of the sheet plays an incredibly important role at Heidelberg, especially in the 50 x 70 format range. The success of the Speedmaster SM 74 with more than 28,000 printing units delivered since 1994 would have never been conceivable without the flexible perfecting device. The perfecting presses in the Speedmaster SM 74 series are a highly effective production tool for materials with maximum grammages of approx. 250-300 gram per square meter and come with up to 10 printing units for 5/5 printing in a single pass.
As before, the successful Speedmaster SM 74 eight and ten-color models are still available as "long perfecting presses". With the newly developed feeder and optimizations in sheet travel, they are the most productive solution when it comes to printing brochures or annual reports on the usual grammages of up to 250 gram per square meter.
