D2019DISCUSSIONIt follows that the estimated equivalent black area of agray or colored speck would be smaller than its actual area in inverseproportion to the intensity of its color contrast with its ba

49、ckground. Theequivalent area of a black spot in a dark brown paper would beconsiderably smaller than its actual area, and rightly so, since itspresence would not be as pronounced as it would be if it wereembedded in a white sheet.double fold, n of paper, one complete oscillation of thepaper test specimen, during which it is folded first forward,then backward about the same base.
