Konica Minolta Spectrodensitometer FD-7 allows for color evaluation after considering the fluorescence of paper under any illuminant, even D50 (ISO 13655 M1). A variety of features like standalone measurements, scan measurements and light measurements are possible within a single device. The company is noted for delivering world’s only handheld instrument capable of measuring both density and color of printed matter for any illuminant, irrespective of whether the substrate contains fluorescent whitening agents (FWA). Both Fluorescent Spectrodensitometers FD-7 and FD-5 contain the most innovative technology called VFS (Virtual Fluorescence Standard). The technology by Konica Minolta makes use of optical, sensor and software technology developed through long years of experience in color-measuring instruments. This allows for virtual measurements for a range of illuminants while considering the influence of fluorescence.
