I'm measuring and profiling a CMYK printer with my eye-one (rev. b no UV
cut) and when I made a profile, I get the following result: FWA content
= 0.332844. I'm still using version 0.60. This compensation assumes the
Eye-One internal light (something near illuminant A) in the calculation
or this only occurs in the newer version .070 ? According com GG's paper
about FWA compensation, the spectrophotometer internal light is an
important variable, AFAIK...
Is this an RGB device ? There are known issues with V0.60 profile and
FWA compensation when working with RGB. A possible workaround is
to use spec2cie to convert from spectral to tristimulus, or try the
V0.70Beta2 profile.
