Digital BW, The Print

Jerry, I hate to ask, it already seems like you spend more time than 
you have to on these questions, but.
In a post today, you say you get good b&w with the mis color ink, 
adding 8M and-5C, on the sliders.
Is that all you do?  No changes to brightness, saturation, contrast??
I will try that combo now and let you know how it works.
What paper are you using?  I 'm using eith LPM of Somerset enhanced 
velvet. with the 1280.
Thanks again.
David
