ABSTRACT:
In a method for reinforcing a flexible sheet such that the flexible sheet will retain desired topographical features, a flexible sheet is positioned on a surface of a magnetic chuck. The surface of the magnetic chuck has a topography, such as a perfectly flat topography, such that a magnetic force of the magnetic chuck causes a first surface of the flexible sheet to be formed into a reverse topography of the topography of the magnetic chuck. A frame having greater rigidity than the flexible sheet is secured relative to the flexible sheet as the first surface of the flexible sheet is formed into the reverse topography of the topography of the magnetic chuck by the magnetic force of the magnetic chuck. The flexible sheet together with the frame secured thereto are removed from the magnetic chuck. The first surface of the flexible sheet retains the reverse topography of the topography of the magnetic chuck when the flexible sheet is removed from the magnetic chuck together with the frame secured thereto.
