HEATSET WEB OFFSET PRESSES -- Some Like It Hot
The Rotoman S produces signatures of up to 24 pages in a single-web configuration. High-productivity features include plate changing in minutes and MAN Roland's PECOM press control system, which facilitates such benefits as off-line makeready and Quickstart 2 for fast and low waste changeover.
"One of our larger users defines his uptime challenges succinctly when he states that a very key measurement for his company is how long it takes to get a press back on the clock once it stops running," relates Clark.
"He applies that benchmark to both planned stoppages (such as end of form run) and unplanned (web break) ones. MAN Roland web press systems perform well under this criterion, principally because of how thoroughly we integrate all of the essential auxiliary equipment into our PECOM control system," Clark adds.
Fully Automated System
Another vendor, Komori America, addresses heatset printers' need to be competitive with its long grain, eight-page System 20 web offset press. The press is 20˝ wide with a 23˝ cutoff, and is typically equipped with a folder and sheeter. The press has a full complement of automation required to achieve short makereadies with minimal waste.
"Our customer base is looking for ways to be more competitive, particularly on some of their longer run work that they are currently losing to competitors," notes Terry Bradley, technical director of web systems for Komori America. "The System 20 significantly reduces turnaround time because the product is dry and ready for the next production step. And print quality is equivalent to that of sheetfed."
Likewise, Heidelberg is providing its customers with the tools they need to remain profitable with its complete range of conventional and gapless technology presses for every heatset web offset application. Heidelberg's leading presses in the North American market are its gapless Sunday 2000 and the M-600 models for short- to medium-run commercial and publication printing, and the Sunday 3000 for long-run catalog and publication printing.
