Digital BW, The Print

OK, I've given up the the Lyson Quad-Blacks.  They're fine as long as you
want a nice magenta color in the mid-tones.  And a big thank you to Greg at
InkJetGoodies for having real integrity and giving me a Small Gamut cart, an
excellent place to order from!

I'm curious what type of adjustments and/or work flows others are using (I
have an Epson 860) for this ink set to give neutral to cold-tone
blue/blacks?

Thanks to all.

Rick
