Hi all,
the media wedge CIELAB differs from the (popular) media wedge CMYK.
The latter one is needed for proofing where you all CMYK char.-data
might be associated to those fix CMYK values (from IFRA26 over
GraCol2007 to FOGRA39).
The text files mentioned containing the subset (72 patches) out of the
big test chart (ECI or IT8/7-4).
The CIELAB mediawedge was made for analysis and evaluation of gamut
mapping and general color transformations. There for you have a look
at the original and the transform CIELAB values ...
regards
Andy Kraushaar
PS: The CIELAB media wedge is currently not available.
