Systems and methods are provided to address the potential impact of lighting conditions/light sources on color measurement and/or color matching, particularly as such light variation relates to UV levels. The systems and methods generally include a UV visualizer that is adapted to establish and/or compare UV profiles for individual substrates/samples, e.g., print materials, under various illuminating conditions. According to the disclosure, it is possible to determine both (i) how a sample (e.g., a printing material) responds to UV light, and (ii) the amount of UV light under which the sample is viewed without the need to measure the excitation pattern of the sample/paper or the spectra of the illuminating light. In this way, a true color reading and/or color match may be achieved. Color corrections may be implemented that necessarily address the level of color brightener, if any, in the substrate or paper to be printed upon.
