摘要：
An image forming process capable of providing photographic images having extremely high contrast and high resolution for use in photoengraving is disclosed, which comprises processing an image-wise exposed silver halide light-sensitive material having at least two silver halide emulsion layers on a support, one of said emulsion layers providing a contrasty gradation and the other of said emulsion layers providing a soft tone gradation, with a hydrazine contrast development system, a tetrazolium contrast development system or a lith development system, wherein the gamma (.gamma.) value of the portion having a density (D) from 0.3 to 1.5 on the characteristic curve obtained is less than 10 and the gamma (.gamma.) value of the portion having a density (D) from 1.5 to 3.0 is at least 10.
