Digital BW, The Print

Well I've just got done with a big color archiving/printing project, and 
I've had some time to work with the EZ inks on my c86, using Paul's 
settings/curves and Epson premium semi-matte and Innova Fiba print.  In 
fact I just did my first 8x10 print from a scanned 4x5 negative, and I'm 
noticing some coarseness in smooth toned, light areas. At first I 
thought this was a result of sharpening, and so just for fun I turned it 
all off: The coarseness was still there. (It looks like fine grain.) 
It's worse on the Innova than on the Semi-matte Are the R200 and R2400 
free of this coarseness? I also am getting some micro-banding, at least 
I assume that's what it is.
