Yes. Thats all that should be necessary with the UT3D inks, the extended 
grays target is for color sets, not for graysets, which are automatically 
"extended"...

There is a good chance that the PFP2 profiling process will cover any 
variation issues with the inks.

variation was in some other factor it could be problematic. But what is 
challenging in manufacturing such insets is the tonality, and what PFP is best at 
controling is that same factor, so there there is a good relationship between 
the two; it allows the ink company to produce inks with less difficultes, and 
allows the end users to get the precision and control they desire.

Should be able to tint the images warm in Photoshop, and print through that 
same neutral PFP2 profile to get what you want for tints. Use the PFP profile 
in Custom Proof Setup so that you can tint visually, and see what tints are in 
the gamut of this inkset, and what tints are not. General tints in Photoshop, 
done without the softproof function on, don't work for such inksets.

You may have to reprofile once you use these inks up and purchase new 
supplies, if there is significant variation. But thats only a ten minute process.
