The ink application roller (15) has an outer hydrophobic coating (29) and an elastic coating (27) underneath the hydrophobic coating. The hydrophobic coating consists of at least one non-elastic, especially solid, material and is at least thin enough to have a desired flexibility and thick enough so underlying coating structures do not penetrate it.
