Abstract

Reproduction photographique de plaques présentant une information vidéo et audio codée de structure très fine. On utilise un diazosulfure aromatique comme système photosensible, après quoi, après exposition et par contact avec un sel de métal, une image de germes métalliques est provoquée, qui est développée, par développement physique, en une image métallique représentant un noircissement inférieur à D = 1. Application : copie de plaques.Photographic reproduction of plates showing very fine structured coded video and audio information. An aromatic diazosulfide is used as a photosensitive system, after which, after exposure and by contact with a metal salt, an image of metal seeds is caused, which is developed, by physical development, into a metal image showing darkening less than D = 1. Application: copying of plates.
