Digital BW, The Print

Hello,

This is my first post.  

I thought I was the only one who liked the look of Black Only prints, then I found this list.  I didn't realize that so many did it and that it was talked about so frequently the abbreviation "BO" was coined for it.  By the way, I don't mind that 2200 matte black is a little warm.  

I downloaded Roy Harrington's QuadtoneRIP because I wanted to try the Black and Light black only print on my 2200.  Now that is warm! Actually, in comparison, my black only prints look totally neutral.  

Now, here's the question that I have.  I've tried a bunch of different densities along with printing out the 21 step grayscale step wedge.. The problem is I can't get deep blacks that still separate. When I get the 100% and 95% to separate, the blacks just don't look that dark.  How can I fix this?  The step wedges I've printed with the black only look great despite the slight roughness.  I've set everything according to the recommended.  The highest density I can set while still getting shadow separation is about 1.1.  

The more tests I make, the more I feel like I'm running around in circles.  Help please!

Thank you!
