Digital BW, The Print

When I use the QTR to print on either Epson Premium Luster or Ilford 
Smooth Pearl papers, my prints have a strong brownish hue to them. 
Even with a Curve of 100% cool, they are still printing out brown.
Why is this happening? All the QTRgui settings are correct and I
converted to the Photo Gray profile.

By the way, I should add that the QTR works great on Enhanced Matte 
paper (looks far superior than printing from PS and with magenta
tinge to them under the flourescent lights). What a relief.

I'd appreciate hearng back from someone who might be able to help me.

Thanks!
Steve
