3/ An exposure holder according to claim 2, wherein said first frame is vertical and said second frame, in its first position, is at a small angle relative to the first frame.

4/ An exposure holder according to claim 3, wherein each of said frames has a bottom edge, and wherein said holder further comprises means for establishing a pivot axis along said bottom edges, said frames being moved towards each other by pivoting about said axis.

5/ An exposure holder according to claim 3, wherein the means for positioning and holding said panel comprise means for supporting panel via its top edge.

6/ An exposure holder according to claim 5, wherein the means for supporting said panel comprise pegs projecting into the inside face of the top edge of the first frame and holes formed in said panel close to its top edge and suitable for cooperating with said pegs.

7/ An exposure holder according to claim 3, further including means for establishing sealing between the peripheries of said frames, and wherein said means for creating suction comprise suction means for sucking out the gas contained in the volume defined by said frames carrying their artworks and said sealing means.

8/ An exposure holder according to claim 7, wherein said suction means are disposed close to the top edges of said frames.

9/ An exposure holder according to claim 1, further comprising synchronization means for synchronizing the means for creating suction and the means for moving said frames towards each other whereby both artworks are pressed progressively against both faces of said panel, starting from the bottom edges of said artworks and going up to their top edges.

10/ An exposure holder according to claim 3, wherein said means for positioning the artworks relative to said frames comprise positioning pegs projecting from the inside face of the top edge of the first frame and holes formed in said artworks close to their top edges and suitable for cooperating with said positioning pegs.

11/ An exposure holder according to claim 1, wherein the displacement means comprise means for moving the panel towards said first frame and means for moving the second frame towards the first frame in such a manner that the distance between the first frame and the panel remains substantially equal to the distance between the panel and the second frame.

12/ An exposure holder according to claim 1, wherein the means for holding an artwork to a frame comprise a peripheral groove formed in that face of said frame which is to receive the artwork, and means for connecting said groove to suction means.

14/ A holder according to claim 13, wherein said means for creating suction comprise deformable sealing means mounted on the periphery of said first and second supports, and means for connecting said volume to suction means.
