QTR-Quadtone RIP

Hello,
I use a Piezography ICC system (K3I guess) on a 1290 printer and I
would like to use the QTR Rip.
Where can I found the Printing model and the curves?
May I use the differents tools included with the QTR (and a
densitometer) to build my own?
Any help will be appreciate.
Thank you,
Christophe
