Investigation of colorimetry for samples on fluorescent paper
Fluorescent Whitening Agents (FWA) have been widely used in the surface cotour industries. However, there are problems to apply colorimetry involving samples containing FWA. The main problem is large variations of UV content in the light sources used for instrumental measurements and visual assessments. In this study. printed samples were prepared on substrates containing with and without FWA. They were measured by spectrophotometers and visually assessed in a viewing cabinet to study the effect of the inclusion and exclusion of UV component. It was found that instrumental results did show a slight effect due to the presence of FWA, while there was hardly any difference in visual perception.
