CIE Whiteness % former SCAN-P 66:93
The impression of whiteness consists of the perceived lightness and the hue, i.e. how much the hue deviates from neutral. The CIE Whiteness of the perfect white is 100.
CIE Whiteness Fluorescence % former SCAN-P 66:93
The CIE Whiteness Fluorescence measures to what degree the whiteness of the paper is affected of the fluorescent compounds. With fluorescence it’s possible to get a whiteness above 100 %, as invisible light is transferred to visible. (See Brightness Fluorescence above)
