<p>In a method of reproduction of original models not possessing in particular metameric coloration, these respective originals are explored, in as much as concerns their degree of color, by a three component method and are after a treatment by a mixture of the color of the scanning signals obtained, reproduced by means of a color reproduction systeme. The scanning signals are thus transformed into corrected primary color signals. The accomodation of the scanning signals, or signals derived from them, to at least one color reproduction system, the interventions for the modification of the graduation or the interventions intended to alter the restitution of the different colors in the total image or in discrete zones of this image, are carried out only after the transformation of the scanning signals or of the signals derived from the, into corrected primary signals. Particular methods and appliances for the acquisition of three corrected primary color signals as well as for the establishment of signals relating to the concentration of dyes, depending on these three primary color signals, are also described. </p> |
