Hello Gerhard,
thank you for your reply.
I had calculated the Lab and XYZ values in the reference table from the
transmission data of the target and the tungsten spectrum.
Colprof/profcheck/... will do this calculation for you, if you specify -iAand
put the spectral reflectance/transmission data in the .ti3 file.
I don't remember if there exist a flag where you can tell colprof/profcheck/...
that the XYZ numbers in the .ti3 file are based on tungsten illuminant instead
of D50.
Regards,
Gerhard
So I do not see,
why I should need any additional spectral data. Also the documentation
offers the option of choosing the tungsten spectrum with -iA. So I had
assumed the spectrum was internally available.
