The image (2) is exposed at least twice on the same film or plate (6) using a stochastic raster (5) which is moved relative to the film or plate after the first exposure but before the second exposure. The image is reproduced on a light-sensitive layer (6a) of the film or plate using a raster with a random distribution of dots, the toner layer (5a) in the raster being arranged to face the light-sensitive layer, preferably so that it is in direct contact with it. |
