Digital BW, The Print

Paul,

I don't have a 2000P here any more, but I found my 2000P folder and looked
at the EEM 21-step test strip; it looks fairly good to me.  So, I'm not sure
why you're not getting smooth results.

Here are the visual densities on EEM:

With Color Controls checked: 
K = 1.72, C = .41, M = .92, Y = .37, LC = .30, LM = .56;

With NCA checked:
K = 1.71, C = 1.31, M = 1.31, Y = .51, LC = .50, LM = .48.

I would have thought that my RGB curves would have been smoother than the
grayscale curves, but when I compare the PremierArt RGB and GS prints, if
the GS file was 16 bit when the curve was applied, the prints look about the
same.  In both cases the dots are barely visible even with a loupe.  PA,
like PhotoRag, does tend to hide dots better than some papers.

I once had a contact who had a 2000P and 1280.  Even though the 2000P dots
may be a bit larger than the 1280's, he was convinced that the 2000P had a
better dither and looked smoother than the 1280.  I was not entirely
convinced of his arguments, but the high resolution scans he had comparing
the 2 certainly didn't show the 1280 as being clearly smoother.  They looked
very close to me -- which is good.
