摘要：
The invention relates to a method and an apparatus for copying transparencies to a light-sensitive material, the apparatus including an illuminator for illuminating the original, wherein the illuminator has a plurality of individually addressable pixels which can be switched to light or dark and which are controlled according to a raster image. The density values of the original are first determined with a predetermined spatial and gray-scale resolution and the raster image is subsequently generated from the density values of the original according to the error diffusion method.
