The paper type or similar sheet substrate for receiving an image in a printing or reproduction process. Said sheet (2) has a number of uniformly distributed holes (3), 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 process used, the perforated sheet (2) can be associated with an unperforated sheet applied to its reverse side, thereby providing a lining sheet for said perforated sheet.
Le support en forme de feuille genre papier ou similaire est destiné à recevoir un visuel par une technique d'impression ou de reproduction. Cette feuille (2) est munie d'une multitude de perforations (3) régulièrement réparties, pour l'obtention d'un papier transparent une face susceptible d'être appliqué sur une vitre par exemple. Coté extérieur, la lumière éclaire le visuel et limite la perception des perforations; coté intérieur, les perforations laissent passer la lumière et le document paraît transparent. Cet aspect de transparence est avantageusement renforcé par l'application d'un à-plat noir sur le verso, permettant l'absorption de la lumière. Selon la technique d'impression ou de reproduction utilisée, la feuille perforée (2) peut être associée à une feuille pleine, appliquée sur son verso et venant 1a doubler.
