QTR-Quadtone RIP

Hi,

I am new to quadtone and piezography which I have just setup for my
4800. I want to use Epson Ultrasmooth FA paper but there is no curve
for this paper. Can someone help me create a curve or profile for this
paper. It would great if I can get step by step instructions. BTW, I
do own a Sypder print 3 Spectrocolorimeter to help with the process.
Thanks
