Hello John,

Here are the density values for the three profiles:

black-only with a 75% GLOP spread even across as an ink:
0.05 0.13 0.20 0.28 0.36 0.45 0.54 0.64 0.74 0.87 0.99 1.11 1.24 1.37
1.49 1.61 1.73 1.90 2.08 2.23 2.38

cool with GLOP applied using a dedicated GLOP printer - I haven't
figured how to apply GLOP in this case (and sepia) because with the
two toners I got ink overload:
0.07 0.14 0.22 0.32 0.41 0.51 0.63 0.73 0.84 0.97 1.10 1.22 1.35 1.51
1.63 1.79 1.92 2.11 2.29 2.38 2.43

sepia with GLOP (same as above):
0.07 0.14 0.22 0.32 0.41 0.51 0.63 0.75 0.85 0.98 1.11 1.24 1.37 1.52
1.65 1.80 1.93 2.11 2.27 2.37 2.42

I'm sure I can get higher dmax using a dedicated GLOP printer for the
black-only case. I got dmax of 2.71 for the 1160 / UT-FS /
Ilford-Smooth-Pearl setup.

Having never seen a b/w output from a 2400 I can't really say whether
the R1800 is a contender in the b/w department, but I'm amazed by its
output. The R1800 with QTR support is definitely the most versatile
machine that I know.

Now only if I can figure out how to apply GLOP to its output to get
the best density in one pass without having to use a dedicated GLOP
printer. This is the same issue with the Epson printer driver. Maybe
this is where the K3 inkset is superior.

A special note to Roy. Is there a way to make QTR dump GLOP for me
even where a pixel value is 255,255,255?
