Hi Eric,

I haven't tried any gamma 1.8 workflows but I think this is what you need to do.

You need to get everything into gamma 1.8 spaces.
Assign Profile ... Target-21.tif file to Gamma 1.8   (not Convert to Profile).
I'd switch the Color Settings ... as well to gamma 1.8 and Apple RGB or
some other gamma 1.8 color space.  I don't think this is critical but if any
conversions get done they are in the correct gamma.

Now print the Target through ImagePrint and follow the same profile
creation method.  This profile ought to be useful for gamma 1.8 files.

As far as converting color images to grayscale 1.8, whenever you Convert
to a different gamma space you change the data values.  Whereas Assigning
just changes the space name not the data.  If you are going to be editing
in the new gamma 1.8 space based on the softproofing I don't think it
matters.  I'd try to get it into the right space while still in 16bit if possible.

(BTW, doesn't ImagePrint have any softproofing capability?).
