Digital BW, The Print

I have just completed my first curve for Ilford Smooth Pearl, using 
Lyson Fotonic ink printed on an Epson 2100. Quite an effort !! I 
think I need to lie down for a week to recover. However I would 
appreciate some comments when evaluating the tone of a print and the 
corresponding Lab values, a and b. I have, I think a grasp on how the 
inks vary these values, and the effect that the paper has. However 
what do you look for when evaluating the figures ?

Just want to know if I'm doing it right.

Thanks

Peter.
