Abstract
A method of obtaining a color proof in which color-separated images are successively exposed onto colored light-sensitive layers. The layers are all transferred to a printing paper. The exposures are performed through a mask having dots of predetermined density and diameter, depending on the type of printing paper. If the color-separated images are positive, the dots are transparent on a dark background. If the color-separated images are negative, the dots are dark on a transparent background and additional exposures are made without the mask.
