Digital BW, The Print

I have UT7 inks in my 7600. When I print without using curves or 
sliders, I get a good neutral print. But when I use any of Schwab's 
curves or Paul's slider suggestions, the ink lays down blotchy - as 
though it was sponged on. The neutral setting looks almost purplish. 
I stay on RGB,8 bits per, set paper to Smooth Fine Art, 360 dpi, HPR, 
Epson driver. This is a new problem. A few months ago, I was able to 
get all the tones from cool to sepia - with the same quality print 
using the curves and/or the sliders. 

Also, perhaps Paul or Bill can suggest slider settings or a curve 
just a little warmer than carbon and not as brown as sepia?  

Thanks for any suggestions -           Arlene
