Offset Printing--Pressing Ahead

The second innovation, moveable lower folders mounted on transverse rails, allows the folders to be optimally positioned under the formers according to the web configuration for each print run.

Heidelberg Web Systems showcased the 24-page Sunday 2000, as well, which is also available in a 16-page format. The show model was a five-unit, single-web press running with the PCF-1 pinless folder. Like all Sunday Technology presses, it features gapless blankets. Aside from paper savings, they eliminate vibration-related defects such as bump streaking, doubling and web flutter. With its wider, six-pages-across configuration, the 24-page Sunday 2000 prints 50 percent more pages per cylinder revolution than a 16-page press—and with no additional manning requirements. The press also features semi-automatic plate changing, as well as automatic cylinder positioning and locking.
