Out Of Gamut problem

I have setup a Custom Proof Setup for my Epson 2100 printer. When I select
Gamut Warning I see in gray those areas of the image that do
not come within the gamut of the printer profile. I want to desaturate just
these areas so I went into View, Color Range and selcted the
Out Of Gamut option on the dropdown. I expected the gray areas on my image
to be selected but that is not what happens. The areas selected
seem to bear no relationship to the Out Of Gamut gray areas. Am I doing
something wrong or is it that I am misunderstanding something.
Any help would be gratefully received.

The OOG option with View > Color Range shows the out of gamut colors
ONLY for the current CMYK option you've made in the basic color
settings, not the current soft profile profile or any other ICC
profile, so you can't do what you're trying to do with that tool. I
tried the same thing a few years back and learned this the hard way.

Im not sure if it's exactly what you'r looking for:

Want to "select/activate" the "gamut" areas, do this:

A) Menuebar; View > (+Select) "Gamut Warning"
B) Menuebar; Select > Color range; then
C) open inside that window the popup of "select"; and
D) choose "out of Gamut";
E) hit "ok" and
...you have your "selected" gamut areas..

( ;-) hope it helps

Look at Edit > Color Settings > Working Spaces: CMYK to see what your
default CMYK space is.

When you do the steps you describe with Color Range then the 'out of
gamut' colors that are shown are for that CMYK color space. Colin
doesn't want that ... he is soft-proofing with an Epson 2100 ICC
profile and wants to select the out of gamut colors for THAT profile,
which are different than the CMYK oog colors.

So what you are describing is true but doesn't allow you to select the
out of gamut colors for anything other than the default CMYK working
space, not for a soft proof.
