I started to read another article elsewhere that described making an opaque mask to cover the entire photographic paper. In the area of the mask that should contain the signature block, a window was cut to the appropriate size. The window contains a piece of film that has an image the signature (in negative). After exposing the primary photograph, the mask is placed over the photographic paper and the signature is exposed to the desired density.
