Abstract
A roller rotary offset printing press has at least one coating unit and at least one printing unit. The coating unit comprises at least one coating unit and at least one printing unit. The coating unit comprises at least one chamber blade having a water-based coating and at least one anilox roller. The coating unit is arranged along a transport path of a print stock downstream of the at least one printing unit of the roller rotary offset printing press. At least one pair of two rollers is arranged that together form a coating gap. At least one roller of the at least one pair is in contact with the at least one anilox roller. The conveyed volume, at least on one part of the shell surface of the at least one anilox roller, is filled by an amount of coating, the mass of which, based on this part of the shell surface of the at least one anilox roller, minus a water portion, equals, on average, a maximum of 4 g/m2. A blanket having several layers can be placed or is placed on at least one roller of the coating unit.
