AbstractAlthough there are several alternative forms of contrast the computation of the contrast of printed materials always involves a ratio of luminances at a luminous border. In this report contrast is defined simply as the ratio of the luminance of the darker zone to that of the lighter zone, except where noted. By this definition, contrasts range from unity for very faint luminous border to approximately zero for such prominent borders as black ink on white paper.
