摘要：
A method for making a color proof in a photo-mechanical process. The method comprises a step for exposing a silver halide color photographic light-sensitive material to light through a black-and-white halftone dot image, and a step for developing said silver halide color photographic light-sensitive material with a color developer. The photographic material is comprised of at least three silver halide emulsion layers which are different from each other in spectral sensitivity thereof, and at least one of these silver halide emulsion layers contains a specific yellow coupler and the color developer contains a specific color developing agent. A halftone color image having a color tone similar to that of image printed with printing inks can be obtained by the simplified process.
