CIE L*u*v*, CIE L*C*h* uv, CIE xyY and DIN Lab99
The Premium-version of SpectroDens enables the display of additional color spaces,
which might be used mainly in industries outside printing:
CI E L*u* v *, CIE L*C*h* uv, CIE xyY and DIN Lab99.
Dierent formulas for calculating the color
distance ∆E* can be selected as well. The
Euclidean color distance ∆E* a*b* is the most
widely used, although it is criticized that for
certain areas in the color space the visual per-
ception of color distances does not match the
∆E* a*b* color distance accordingly.
The ISO-Check function features the use of
the SCCA reference value correction (select-
able in the ISO-Check setup).
You will nd a comprehensive description of
the SCCA function on page 59.
