Abstract
Various methods of reproduction usual in the graphic arts industry are compared as to their colour-rendering qualities. The methods of reproduction examined differ according to the nature and the number of their intermediate photographic steps. Colour rendering results were obtained by a combination of experimental methods and calculation. The reproduction methods are compared for the case of a perfect grey reproduction, wherein use is made of a definite set of three-colour printing inks.
