manroland Previews New ROTOMAN Configurations
manroland plans to offer two new versions of its ROTOMAN press, described as the best-selling 16-page rotary press on the market. There are currently over 500 ROTOMAN presses in operation around the world.
The press manufacturer will launch the ROTOMAN HiPrint, focusing on print quality within standard web-offset price/performance ratios, and the ROTOMAN DirectDrive, focusing more on automation.
Every printing tower of the ROTOMAN DirectDrive press is equipped with two motors and the cylinders can be moved apart so that the paper web runs are contact-free between them. According to manroland, this means that the complex diversion of the web through rollers is no longer needed, nor is the use of energy- and maintenance-intensive air bars or blind plates.
The press manufacturer continues to explain that the wide separation of the printing cylinders results in greatly simplification of imprint changes and temporary usage of coating and spot colours.
For job changes with the ROTOMAN DirectDrive press, an operator can insert new plates laterally into encapsulated cassettes, while another job is on press. Then, after the start command for the job change, autoprint attends to all other setup tasks. The plates are automatically changed and all settings are optimized until the press recognizes the prescribed quality level. According to manroland, this can reduce makeready times and start-up waste by 50 percent.
The ROTOMAN DirectDrive press, according to manroland, provides no loss in print quality at 70,000 copies per hour. The ROTOMAN HiPrint press, meanwhile, is designed for producing high-quality print at speeds of up to 55,000 copies per hour.
The ROTOMAN HiPrint is based on the original ROTOMAN inking unit with extensive temperature control, which allows for the use of various conventional blankets, as opposed to the restriction of metal back blankets or sleeves.
