Thanks Paul - it looks pretty good to me. It will be nice to be able to print matte and glossy from the same ink.

Mike,
This is a 300 dpi RGB scan of the
Northern Light test image:
http://www.paulroark.com/BW-Info/NorthernLight-Arches-GCVT.jpg
The print was on a letter
size piece of Arches, using the "dB3, v.2"
profile, which has a total delta B from paper base to max.
Lab B of about 3.5.
(So, this is not the dB2
profile shown, but that on letter size that one is a bit of
a stretch for that target. The black (MK) dithering and
paper patterns in the midtones are going to interact with
the gradients and leave artifacts.)
Keep in mind that I am
targeting Arches full sheets -- 22 x 30 inches. So, on
this letter size, unsharpened (cheap) flatbed scan,
you'll see a lot more impact on the image from the
medium than I would someone looking at a large print.
(You'll also see dust on my scanner.)
The image was gray gamma
2.2. So, in printing I applied my conversion curve. This
compresses the dark end. While the flatbed didn't
separate the bottom row of Keith's 51-steps very well,
my spectro does, and the dark end will get a bit darker as
the MK cures overnight. That is, there is appropriate
separation there even if the scan does not show
it.
BTW, I use the dB3 carbon
core for what I consider the best Neutral profile, not the
dB2 core. But for many images, where someone wants the most
archival full sheet Arches print, the dB2 carbon profile can
do a very good job.
FWIW
