This particular instance I assume is my error as I'm not even remotely
close. I'm still trying to figure out where I've gone wrong. 0/0/0 RGB
prints on Epson photo paper with a measured LAB value somewhere near 30/0/0.
Hue looks fairly accurate but the prints are quite light and washed out.
I've re-measured and built the profile twice with the same results.
My experience with a previous version of ColorSynergy was that it did a much
better job on a fairly well behaved device as opposed to building a profile
for a printer that's WAY off from a normal condition. That may be part of
what's going on here. Printing the target through PressReady with
simulation turned off results in a rather dark set of target patches to
measure. The target optimization step that CompassProfile does lightens the
target considerably and I would think helps to provide a more meaningful set
of samples from which to construct a profile.

I must have missed that. I'm surprised at that result as I see no
noticeable difference between the two as far as image quality goes (on a
1270). Were you running PressReady with all proof simulation turned off and
with a custom profile? I don't see how the driver would limit gamut in any
significant way in such a situation. I used nothing but the Quickdraw
driver with this and other Epsons for quite some time and was very pleased
with the results. I like PressReady more primarily for the smoother
workflow in a proofing situation where you are trying to get the Epson to
simulate something like a contract proof. That's my main use for Epson
printers and I'm quite pleased with how accurately, easily and inexpensively
the PressReady/Epson 1270 combo can do this.
