ABSTRACT:
To planarize an electroformed, magnetic metal sheet having micropatterns, the metal sheet is clamped on a magnet and is mechanically processed on the back side of the metal in such a way that it assumes a plane-parallel shape. Metal sheets can be used which are not stress-free and are obtained in a fast electroplating process. Multiple copying is possible.
