Abstract

This method is aimed at checking the quality of reproduction of graphic elements obtained by means of a cathode-ray tube on a photo-sensitive material. This method allows the checking in a simple and rational way of the printings obtained from a photosensitive material. The checking is carried out by introducing a network of supplementary points which react differently according to the illuminating and developing conditions.
