An apparatus and method for evaporating a coating solvent from a coating on a first substrate surface of a substrate and for minimizing the formation of mottle as the coating solvent is evaporating. A drying oven includes an enclosure having an inlet and an outlet and defining a first drying zone. A plurality of drying subzones are within the first drying zone. At least two of the plurality of drying subzones employ different and controllable drying conditions. Physical barriers are not required to create the plurality of drying subzones.

[ We claim:] [59.] A method for evaporating a coating solvent from a coating on a substrate with reduced formation of mottle, the method comprising:providing an enclosure defining a drying zone with a plurality of drying subzones;transporting the substrate through the enclosure; andselectively controlling a static pressure difference between a lower interior portion of the enclosure within each of the subzones and a reference point to reduce the formation of mottle.
