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 printing plate is then clamped to the substrate by means of attraction by a magnetic force from behind the substrate. The viscous material penetrating portions of the printing plate are filled up with a viscous material for forming projections. 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.

Abstract: The present invention relates to a screen printing apparatus comprising a support mechanism for supporting the material to undergo printing; a printing plate in which an ink penetrating portion is formed possessing the shape of the print; a printing plate housing for housing the printing plate at a position in contact with the material to undergo printing; a slider which is capable of bi-directional horizontal movement with respect to the printing plate; a slider driving mechanism for driving the slider bi-directionally; a first squeegee and a second squeegee for spreading over the printing plate ink supplied to the printing plate; and a squeegee switch mechanism installed in the slider for supporting the first squeegee and the second squeegee, and for selecting one of these first squeegee and second squeegee, and placing the selected squeegee in contact with the printing plate.
