Re: [colorvision_group] Re: Grayscale soft-proofing

Your understanding of how to rebuild the profile with edits is  
correct. But you would adjust the a/b values to the setting where they  
gave you the softproof tone you desire, not simply to zero, though in  
a perfect situation, that would do the trick for neutrality.
