Digital BW, The Print

I'm trying to put together a routine for good quality, neutral glossy prints using the UT14 ink set. (Without adding color dye black ink in the K position.) The paper I am using is Red River Arctic Polar Gloss. I've read Paul Roark's document http://www.paulroark.com/BW-Info/UT14.pdf  and think I have it understood. For the purposes of testing the image I am working with is Keith Cooper's black and white test print. 

This is my image manipulation process:

Open the test image in CS4. Change the Image Mode to RGB Color. Apply the curve UT14-Gloss-N-4.acv. I then print the image. 

Printing the image with printer controls, ultra premium presentation matte paper and gamma 2.2 yields a pretty good print that is very neutral in coloration. However, the D-max of black is low and the mid-range is a bit too light. The surface is very glossy with no non-reflective areas. 

 I created an .icc using QTR. I adjusted a 21-step scale image with the same .acv as with the test image, then printed it and scanned it. Using this and the master 21-step scale image, I generated an .icc. The print with the new .icc is quite different than the print with the  printer controls, but not better. Here are the issues:
	D-max is no better than with the image using printer controls. 
	Color tone has sifted significantly to warm.
	Upper ranges of the mid-tones are too dark.
	The surface has non-reflective areas (the blacks), which smudge, indicating that I am getting Eboni ink into the print. 
	The 21-step scale incorporated in the test image maxes out at 18 and is not in order from about 14 up. 

My question is simply, how do I improve on this process? Is there something in the .icc generation, possibly related to where I'm using the .acv, that I'm not doing right?
