摘要

The simplified process is for fixing a photograph in a passe-partout and uses a self-adhesive rear wall, a cut-out being stamped (B) exactly in the dimensions of the photograph at precisely the correct place under the opening of the passe-partout, enabling the photograph simply to be placed in it. The rear wall is fixed in a hinged manner to the passe-partout. Before the photograph positioned, a partition layer (A) is folded backwards by plus or minus 1 cm. With the under plate already fixed to the passe-partout, the rear plate has to be folded backwards, perfecting the process.
