摘要

The film-type inking system (8) has an ink-duct (9) with an ink-duct sheet (26) inserted between an ink-dispenser system divided into inker zones, and the ink-duct roller (10). During printing, the ink-duct sheet inside each of the ink-zones near an adjustable dispenser-gap is held out of contact with the ink-duct roller. An ink-duct roller and a film roller belonging to the inker unit together form a constant film gap (18) during printing.
