Processing apparatus for flat material and a method for processing a flat material

The invention relates to a processing machine for flat material, comprising a processing unit and a drying device and at least one humidifying device along an intended for transport of flat material transport path, having a first plurality of individual impact zones, which with respect to a transverse direction at least partially offset from one another are, each exposure zone is assigned at least one engaging member and Einwirkelemente an exposure zone at least one other exposure zone are at least partially separated from Einwirkelementen controlled and a method for processing a flat material which is transported along a transport path through a processing machine and processed in a processing unit and in a drying means is dried, and arranged in a plurality of offset in the transverse direction of a mutually different impact zones Befeuchtungseinric Pla an individual amount of water based on the respective exposure zone which is influenced in each case in consideration of the material in the respective exposure zone concerned humidity data is supplied to the flat material.
