ABSTRACT METHOD AND APPARATUS FOR REPRODUCING AT LEAST ONE COLORED SURFACE The method for reproducing at least one colored surface the color of which corresponds to a reference chosen from a color chart is characterized by the fact that during a first stage, there is recorded on a photographic emulsion of the same type a sensitogram developed by means of developing materials of predetermined characteristics, a densitometric analysis of said developed sensitogram is made and the results of said analysis recorded so as to establish an analytical record of the colors comprising the sensitogram with respect to the photographic emulsion and the developing products used. During a second stage, the exposure conditions for the photographic emulsion are determined to reproduce the color chosen from the color chart as a function of the information registered on the analytical record of the colors of the sensitogram. The apparatus used in this process comprises essentially an exposure unit (11), a sensitometer (16) and a central control unit (22).
