Evaluation of the visual perception of crispening effect on desaturated samples on uncoated substrate

This study investigates the effect of crispening on desaturated samples printed on uncoate substrate, focusing on primary stimuli of 45%, 50% and 55% RTV. The crispening effect is described as an enhanced perception of contrast between an object and its background when there are minimal differences in brightness or color. In the experimental part, 20 participants were tasked with "matching" the values based on the ratio rating scale (Stevens) for each of the previously defined primary stimuli, so that the stimuli, regardless of their background (RTV range from 0% to 100%), are perceived as identical. The results of this study may have significant implications for optimizing printing processes and improving the quality of color reproduction on different substrates.
