Gee, could I have it all wrong?? Possible, maybe.

But if I understand that above, you don't have to worry. What you do 
is work away in your custom dotgain profile, even embed it into the 
file. Work on the image until you like all the values, then save 
image.

Then close the image. Then go to edit ,color settings and change the 
profile setup to "photoshop 5 defaults" (greyscale is gamma 2.2). Now 
open the image back up, and tell pshop to discard the embedded 
profile. This will cause the image not to be affected by the custom 
dotgain curve as you just disgarded it and told pshop to use gamma 2.2 
on all images anyway. The image can now be converted to RGB, and pshop 
will convert from an assumed "gamma 2.2" to an "sRGB" profile. No 
values get changed: 60%k is 60%k. The image WILL look darker, but your 
not trying to match the print to monitor anymore.

Or am I wrong about this Paul? I will go look at the post you refer 
to. Let me know what you think...
