Digital BW, The Print

I recently got an Epson 4000 and have been trying the QTR on Epson
Premium Luster paper.  I am having a heck of a time.  I am trying to
get a cold tone selenium (similar to my 1280 with piezography inks)
and am very frustrated.  All of the prints, the modifications I do,
have a brown (sepia) tint.  I cannot get the cold tone on this paper.
 I have gone through the curve creation process and get blocked up
blacks in the lowest 5 black patches on the 21 step patch (L values
all less than 10). 

I have tried adjusting the sliders on the QTR GUI page for the shadows
and the gamma (setting both to 10) and seemingly am getting closer.  I
tried blending a cold selenium tone with a cold tone for a different
paper and the result is even more brown (have tried with 80 blending
towards the selenium).

Also, I am using the 16" wide paper and I set my image size to be 15.8
inches and keep getting told the image is too large and QTR cuts off
both sides of the image.  

Please, anyone, some pointers would be greatly appreciated.

Thanks.

Mike
