Brightness
Brightness is a concept used in two different contexts:
# When referring to image reproduction, brightness describes the intensity of the colours. This is also called luminance, i.e. how light or dark an image is.
# When referring to cartonboard, brightness is expressed as the percentage of light which is reflected from a cartonboard surface at a wavelength of 457 nm (nm = nanometre).
