Offset Printing--Pressing Ahead
The Speedmaster SM and CD 102 series has also been redesigned, including the adoption of the CP2000 Center. This includes the color touchscreen interface and the new print image preview from the CIP3 data, made possible by PresetLink. Equipment diagnosis, visualization of the print process, recording of operating data and job storage are all performed centrally via the CP2000 Center.
The press series also features the new AutoPlate Plus, which allows automatic plate changing of all printing units from the CP2000 Center. Heidelberg has also redesigned the sheet feed system in the delivery unit by rearranging the Venturi nozzles and improving the air supply. CleanStar is a further component, designed to reduce the quantity of powder required. The new InkLine Direct system permits ink to be fed automatically via a central supply system.
Finally, the company announced that the CP2000 Center will become standard on all four-, five- and six-color models of Speedmaster SM 52 presses and demonstrated an optional coating system, which can handle both full and spot coatings.
The Koenig & Bauer Group (KBA) displayed its Compacta 818 press, a 75˝ web width, 64-page commercial press that addresses the need for fast turnarounds. It features dedicated, shaftless drives for the reelstand, infeed unit, each individual printing unit, chill roller stand, draw rollers in the superstructure and an automatically convertible P5 folder. Alongside its console technology that embraces KBA's Logotronic production management system, the Compacta incorporates semi-automatic plate changers and quality control using in-line densitometry. Also shown was a prototype of the new Cortina, a keyless, waterless offset press designed for newspaper production.
To demonstrate large-format perfecting, KBA demonstrated a four-color, 471⁄2x633⁄4˝ Rapida 162a sheetfed press with automatically convertible perfecting for two-over-two work. An automation package incorporates remote register and format adjustment from the console, automatic plate changing and a nonstop system for the feeder and delivery. The press was embedded in a digital workflow via a CIP3 interface to a large-format Barco CTP system.
