The concept of polymer grafting is used to produce the stamps. The stamps thus produced have the great advantage that grafting of a thin hydrophilic polymer on a hydrophobic PDMS surface can render PDMS stamps permanently hydrophilic. With such stamps it becomes possible to print aqueous or highly polar inks reproducibly over days and weeks. <IMAGE>patentJP3496831US6596346JP2002206033US2002098364EP119305626071464
