For Plexiglas works there are no épreuves d'Artistes, they are only certified pieces.
The procedure for obtaining them is as follows: some details of the canvas are photographed with a special technique (Optical Bench). The photos obtained are of such a definition as to allow the artist to "play" with cuts and enlargements of each size.
The expansions are printed on a sheet of silver salts in the dimensions that the artist prefers. The printed image is repainted by Corvino and then inserted between two Plexiglas plates.
