While in Profile Editor, go into preferences and there are five check
boxes. Only one should be checked at a time - maximum two. The first
three, I think they are referred to as Rendering affect the Lab to Device
(RGB or CMYK) tables, which are the portion of the profile that would
affect OUTPUT.
The second two are referred to as Proofing and affect the device to Lab
tables, which affect proofing (soft or hard proofing) from this profile.
So pick one at a time. Make sure one you're done with edits that you save
out a new ICC profile - the edits aren't applied to the profile "live".
The other catch is what reference image to use. While it's not going to
affect the resulting profile if you do it wrong (at least not directly),
if you do it wrong the reference image will look realy bad on screen and
might make it more difficult to edit the profile.
If you are editing rendering tables (Lab to device RGB or CMYK) you want
to open a Lab image.
If you are editing proofing tables (device to Lab) you want to open an
RGB or CMYK image (as appropriate for the kind of profile you are
editing).
The reason why you want to use a Lab reference image in the first case is
because when you open an RGB or CMYK image in Profile Editor, it tries to
ASSIGN the profile you are using to the image - and the profile you are
editing probably doesn't apply to your reference image, so it will look
like doggie doo doo. Using a Lab image prevents this from happening.
In the second case, you *want* the profile you are editing to be applied
to the reference image, because you want the profile to show you how well
it soft proofs, that way you can edit it effectively.
