Digital BW, The Print

I just read thru Roarks info & settings page for the UT-2 inks.

http://home1.gte.net/res0a2zt/UT2-Info-word.htm

I'm curious about the different Media Types he suggests, depending on 
the workflow method you choose.

For the "Slider Controls Method," he suggests "Matte Paper - 
Heavyweight" if using EEM paper.
For the Image Editor Adjustment Curves Method," he suggests "Photo 
Paper" regardless of the actual paper type (or so it seems).

Can anyone shed some light on why you wouldn't use the same media type 
setting for each of these methods?

FYI, using the original UT inkset and Roark's curves on EEM paper, I get 
much smoother gradients with the "Photo Paper" setting, as opposed to 
the "Matte Paper - Heavyweight" setting.

Thanks,

Mike
