Digital BW, The Print

While I have been mostly satisfied with BO on my 2200 using MIS Eboni, 
I want to take the plunge and get started with UT7 and QTR, both of 
which I have.  I don't know much about making curves and wonder if 
there is a link or links where I can get started?  I have done quite a 
bit of searching but haven't come up with any getting started 
formulas.  Also, I am currently using Epson VFA, Moab Entrada Natural, 
and the new fiber papers quite a bit.  I know I will get into writing 
my own curves as I get more experienced, but I would like some help 
getting started.  Thanks.  Nancy
