I don't know the Nikon software part very well but here goesŠ

Assumed: you have a current version of Colorsync and OS and that you've 
run Adobe Gamma to set up your monitor and saved the profile. None of the 
following matters if you've not done this first!

Go to color settings under file menu.
Set Photoshop RGB space to Adobe RGB 1998
You'll see different looking numbers supplied for Gamma, white point and 
primaries, that's fine. Leave them.

Also use Adobe RGB 1998 as the working space for CMYK and grayscale
Lower in  the same window set your monitor to the profile for your 
monitor.
"Display Using Monitor Compensation" clicked on.

From now on all your working space will be "Adobe RGB 1998"

Go to Profile Setup (also under File menu)
Start at "embed profile" for RGB, CMYK, Grayscale (all clicked on)

Assumed profiles are:
Adobe RGB 1998
CMYK (I use Light GCR 280 you may chose something else, talk with the 
printer first)
Grayscale Gamma 1.8

Set the profile mismatch to your choice. I use "ask when opening"

Your Photoshop setup is complete.

BTW:
Colormatch is a space designed for the Colormatch Monitors from Radius. I 
suggest you use this for your monitor setting if you have that monitor. 
Its gamut is slightly different than other monitor spaces and appropriate 
for use with their monitors. Don't use it for working space. Its best as 
a monitor space.

Probably turn off Nikon Color management. I'm not too up on the latest 
version of their software but it probably is part of your problem.

Should work better now.
