Abstract
A method of manufacturing a patterned stamp () for patterning a contoured surface () is disclosed. The method comprises applying a layer () of a pliable material precursor over a master () carrying an inverse pattern () to form a desired pattern () in said layer; curing the pliable material precursor to form a pliable stamp layer () comprising said desired pattern; providing an intermediate stamp structure by adhering a porous pliable support layer () to the pliable stamp layer; releasing the intermediate stamp structure from the master; forcing the intermediate stamp structure onto the contoured surface with said pattern of features facing the contoured surface; forming the patterned stamp by filling the porous pliable support layer with a filler material to reduce the pliability of the support layer; and removing the patterned stamp from the contoured surface. A corresponding patterned stamp, imprinting method and imprinted article are also disclosed.
