| titleOfInvention | Method of photo-etching and photogravure using fission fragment and/or alpha ray etch tracks from toned photographs |
| abstract | This invention relates generally to the formation of images on non-photo-receptive surfaces. In the past the reproduction of images has involved the initial step of screening the image. The present method does not require such screening and the image produced bears a quantitative and positional relationship to the silver grains present in the photograph from which the image is being produced. The invention comprises the method of reproducing a photographic image on a normally non-photo-receptive surface comprising the steps of toning the photograph with substances which combine with or replace the silver grains so that the photograph emits either spontaneously or indirectly fission fragments or alpha particles in amounts related to the distribution of the silver grains in the photograph, and placing the toned photograph contiguous with the surface on which the image is to be reproduced, for sufficient time for the emissions from the photograph to reproduce the image as a radiation-damage image on the surface, the damage areas having a close positional relationship to the silver grains in the original photograph. |
