Illumination Models
Illumination sources have different spectral distributions, causing
colors to appear differently under one light source compared to
another. For example, printed colors that look normal in natural
sunlight shift in hue when viewed under fluorescent and tungsten
lighting. The PCL language allows the user to compensate for the
differences in viewing illumination using the Viewing Illuminant
command. It allows the user to select different illuminations.
