QTR-Quadtone RIP

Dear all, I just discovering the Qtr and although I try to modify curves
this is still unavailable for me.
I have a Epson R800, and I use (theoretically) the right ICC profiles, but
when I try to print Black&White photographies they appears too green
although in my screen are right.

Using the UCEE Matt cool curve the result is very good but I need to add
the Gloss optimizer ink and although I tried to modify the curve the
results are a disaster. Can someone help me and let me know how can I
progress with this issue? Do you think that the "green" tone in my printer
in only my problem or is something that affect this type of printer?.
Thanks in Advance.
