Summary:
Edge-Effect is printing optical density fading phenomenon which is white-gapping between solid and halftone of black area. In this paper, we propose a new method for measuring Edge-Effect based on psychophysical experiments and data analysis method. Our approach is to extract two components both Edge-Effect's integral (PA) and white-peak (PB). Edge-Effect is computed by the weighted sum of PA and PB, where two weighting parameters are determined by psychophysical experiments. By conducting psychophysical validation experiments, the strong correlation is obtained between the proposed measuring method and the perceived scales. The correlation coefficient r is 0.95.
