ISO brightness, fluorescence spectra, and the fluorescence integrated intensity of papers from domestic and foreign manufacturers were studied. The contrast index of the tested paper samples, which is defined as the ratio of the ISO brightness to the paper integrated fluorescence intensity in the spectral range from 380 to 700 nm, was estimated. An alternative method for controlling the paper background fluorescence level was proposed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
