Mark,
How would one test to know if Photoshop cannot parse the color
into 256 tones?
What you say makes sense, but it seems that with some printers
you may not be able to get enough density with just the PDN colors,
even laying down more ink.

Sandy,
My preference for PDN, if the density is not sufficient, is to use Ink
Configuration to lay down more ink. Oddly enough on the large
format printers, this setting is under Paper Configuration and is
called I believe Ink Density.
A good reason for doing this is that once you add black to the PDN
colors, you may get a color that Photoshop cannot parse into 256
tones. So, some colors are unable to render a full 256
tones-one color I tested dropped 50+ of the 256 tones. This
occurs as a sort of periodic posterization in the image. All the
colors used by PDN avoid this.
Best Wishes,

I believe it is about log 2.3. That is, if you print an RGB negative
using all of the inks, that is what you get, or close to it.
If you want to add some black to one of th PDN colors, just make
another 360 ppi layer of the step tablet, fill it with black, and then
blend with the colored layer to give you however much density you
need. With the Epson 2200 virtually any maximum density is possible,
from the 2.00 or so with Green by itself, to around 3.8 or so with
black.
You won't have as much range with the 3800, however.
