Abstract : If a black-and-white image is converted to a chromatic image, each shade of gray in the original becomes a different color in the pseudocolor transformation. The color which gray is seen as in the final image is a function of the densities of corresponding locations in the separations, the spectral content of the exposure light sources, and the exposures used during successive printing, in register, of the separations on color material. The paper describes the problems encountered and the techniques developed for generating separations on the Stromberg DatagraphiX 4060. (Author)
