Digital BW, The Print

I posted before about having dark prints with UT14 on Epson Premium matte with an Epson 
1400. Now I'm having the opposite problems with Kirkland Glossy. When I'm using the ICC 
that Paul has on his website, my prints are way too light. With the warm ICC, I'm getting 
better, but overly dark prints. 

Ideally I'd like to go through the same exercise as I did with the epson matte, and use a 
graycard to create a custom profile. However, I understand the process is somewhat 
difference due to the glop, and perhaps mixing of two channels for black? Is there a 
document somewhere I can read on this?
