PCT No. PCT/FR94/00054 Sec. 371 Date Jul. 17, 1996 Sec. 102(e) Date Jul. 17, 1996 PCT Filed Jan. 18, 1994 PCT Pub. No. WO95/19268 PCT Pub. Date Jul. 20, 1995A paper type or similar sheet substrate for receiving an image in a printing or reproduction process. The sheet has a number of uniformly distributed holes, providing a paper which is transparent on one side and is capable of being applied to a glass pane. On the outside, the light illuminates the image and limits visibility of the holes; on the inside, the holes let the light through, making the document appear transparent. The transparency effect is advantageously reinforced by the application of a light-absorbing solid black area on the reverse. Depending on the printing or reproduction processed used, the perforated sheet can be associated with an unperforated sheet applied to its reverse side, thereby providing a lining sheet for the perforated sheet.
