QTR-Quadtone RIP

Hi all!

I am quite new in BW print using QTR and let say I am still looking
for my BW printing way but I have to say first test prints using QTR,
Ilford smooth pearl, mis ut7 inks on e2100 prints look very hopefully
to me.

ATM I would like to solve one problem. I got only default curves
distributed with QTR for my printer and inks and as I have not
densitometer I am not able to make profiles for desired
ink/paper/printer combination.

So I would like to kindly ask - is there possibility to download/buy
qtr curves? I googled a lot as I searched this discussion group but
without any success.

Thanx in advance for help.
