Thank you for your reply David.I believe I mispoke using the wrong terms. 
I mean't that I'd like to see the spectro read and record CMY
reflection values much like my X-Rite TR810 Densitometer. The 810 is a
Status A (photographic prints)/Status M (negative film) reader. 

I was hoping the Spectro was effectively an acurate Status T
(pre-press proofs, inks) reader that could record these CMY values.

Hope that was a bit clearer.

As for the lack of contrast on the probe tip, it seems others have
noticed this and suggested Sharpies. Guess I'll be looking for one
with glitter (grin).
