PURPOSE: To provide an image formation method in which a color-proof which possesses the excellent net point reproducibility and is approximate to a printed article in the quality of a color image and a black color image can be obtained easily through the light exposure in three times by using a light source having the ordinary wave lenth and utilizing the conventional device.

CONSTITUTION: A color photographic material which has a photosensitive laminated body which includes at least one layer among yellow, magenta, and cyan image forming silver halide emulsion layers, each of which has different spectral sensitivity and includes inside latent image type silver halide particles which are not previously blurred on a supporting body is light-exposed, and a color image is obtained through the development processing. This method includes the color image formation method which is characterized that light exposure is carried out through the scan light exposure system in the light exposure time of 0.002-0.3sec, and the colorproof formation method utilizing this method. The photosensitive lamination body includes the versatile sensitivity type image formation type silver halide emulsifier layer (In particular, an orange image formation type silver halide emulsifier layer having the max. absorptive wavelength of coloring element of 436-500nm).
