Digital BW, The Print

Good morning folks,
I'm ready to see if I can produce some fine prints with my new Epson 1400 and the UT-14 inkset.

 I have installed Photoshop CS4 and Quad Tone RIP in my computer. Following Paul Roark's instructions in his article1400 B&W Inset T-14 I was able to print without much difficulty a fairly good print on Epson Enhanced Matte Paper. Then, I tried to print BO using the Quad Tone RIP software and the same Enhanced Matte paper, but my results were totally different. I got a pretty flat print.

I download Paul Roark's 1400 Profiles and installed them in C:\WINDOWS\System32\drivers\color           
   
I need some help and I have some questions. With QTR, can I only print BO? Isn't any way I can use all my inks as I do when I print with the Epson driver and Photoshop?

Where do you install the curves that come with Paul Roark's Profiles 1400?

I would like to find a good quality paper. Any recommendations?

Thank you very much for your help.

Jorge
