ABSTRACT:
An image forming method suitable for forming a color proof is disclosed. The method comprises (1) a step for exposing a silver halide color photographic light-sensitive material, which is comprised of a support having thereon photographic component layers including a yellow image-forming blue-sensitive, a magenta image forming green-sensitive and a cyan image-forming red-sensitive emulsion layer, to light through a transparent black-and-white halftone image and (2) a step for processing the exposed light-sensitive material to form a color image, wherein the photographic component layers contain a yellow water-soluble dye, a magenta water-soluble dye and a cyan water-soluble dyes and reflective densities of the silver halide color photographic material measured with light of 450 nm, 550 nm and 700 nm are each not less than 0.8, and toe portion gradations of characteristic curves of yellow, magenta and cyan images formed in the light-sensitive material by the processing are each not less than 1.7, and the toe portion gradations of the yellow, magnet and cyan image have the following relation:
