Abstract: A method for manufacturing a substrate having a surface with projections. A printing plate, with a least one part formed from a ferromagnetic material, and which has viscous material penetrating portions for forming projections on a flat surface, is brought into contact with the surface of a substrate.

The viscous material forms a layer on the substrate in a shape that is the same as that of the projections. The printing plate is separated from the substrate and the viscous material printed onto the substrate solidifies to form the projections.
