The printing units of our TOP ALVAR® speed series consist of individual printing units arranged in modular design. As full servo printing units, they boast modern PLC control technology, a functional operating panel and each individual roller is driven by a servo motor. The printing units are designed for 1 to 8 colours according to the customer's production requirements. While the screen roller and format cylinder core remain in the press, the screen roller sleeve and format cylinder sleeve are changed quickly and cost-effectively in the press to ensure the shortest possible interruption to production. In the optionally available electronic job memory, all press-related print settings for a print job are stored in a retrievable manner for repeat execution, so that even smaller print jobs can be executed extremely economically in cases of repetition. The lateral register adjustment with controlled servo motor ensures exact positioning of the printing units. Precise longitudinal register adjustment is achieved by synchronising the speeds of the screen roller, format cylinder and impression cylinder in the press control system.
