Wettable structures that retain liquid layers are defined at surfaces of substrates. The wettable structures include grooves or ridges that are spaced apart by between 10 nm and 10 m and can be defined in substrate or in a layer formed on a surface of the substrate. In typical examples, wettable structures are defined with hydrophobic materials or at hydrophobic surfaces and produce hydrophilic surfaces.

Examples include a sheet processing machine to which a transport path is assigned for transporting sheets. The sheet processing machine includes an application device with an application point for applying material to the sheets. A cooling device including a cooling cylinder is arranged along the transport path, downstream from the application point. An inspection transport body is arranged along the transport path, downstream from the cooling cylinder, and has a sensor device of an inspection unit aligned therewith. Examples further include a sheet-fed printing machine with a simultaneous double printing unit and an application point. A curing device with an LED UV radiation source is arranged downstream from the application point and includes two curing units for drying two opposite sides of sheets. A cooling device of the curing device includes a cooling element with a line system, and the cooling section is arranged downstream from the curing section.
