ABSTRACT:
Method and apparatus for forming halftone images which enables image recording on a process film without reducing the size of the recording area beyond that which is necessary. The method and apparatus is preferred particularly in the preparation of a master printing plate such as a printing plate which includes a photosensitive member having an organic silver salt. According to the method and apparatus, an image recording apparatus propagates error data when there exists a restriction on the minimum recording size and thereby preserves halftone concentration and reproduces intermediate gradation of darkness with stability.
