摘要： The present invention relates to a method for selectively structuring a membrane (1), the method comprising the following steps: a) providing a membrane (1) having pores (4); b) selectively applying an ink (5) onto a first surface (6) of the membrane (1) so that the membrane (1) comprises ink-covered portions (2) and ink-free portions (3); c) allowing the ink (5) to enter the pores (4) in the ink-covered portions (2) of the membrane (1); and d) receiving a selectively structured membrane (1) having ink-filled pores (40) and ink-free pores (41).
