Processing a flexible substrate of a matrix-shaped or lattice-shaped construction material. A first layer thereof is transported in a first transport direction, and a second layer thereof is transported in parallel with and closely spaced apart from the first layer in an opposite, second transport direction through a free region in the evacuable process area. A usable flux of a processing instrument penetrates the first and the second layer of the flexible substrate simultaneously while transported through the free region in an opposite direction. Also, a vacuum processing system including two roller groups, each group including smaller and larger rollers deflecting the flexible substrate. The free region including a processing instrument arranged between the roller groups through which the flexible substrate is transported in an opposite direction and without directional change. At least two closely spaced apart layers of the flexible substrate are transported in opposite directions.

A web transport system for transporting a web of media along a web transport path in an in-track direction, including a liquid application system for applying a liquid to at least one surface of the web of media. An air skive is positioned along the web transport path downstream of the liquid application system, wherein the air skive directs one or more streams of air onto the web of media thereby removing at least some of the liquid that is being carried along with the web of media. A vapor source adds a vapor into the one or more streams of air provided by the air skive before the one or more streams of air are directed onto the web of media.
