The error values that you posted are good and generally what I observe when
profiling my Epson 3880 printer. You say there is "little variation among
the profiles" but don't define what that means.
Two quick things occur to me. Perhaps the i1 is out of specification. You
can download the i1 Diagnostics software from X-Rite and do a quick check to
address that. The second is whether you printed out the patch set WITHOUT
color management. I always use the Adobe Color Print Utility to do this
since Photoshop generally does not allow one to print without color
management (there is a null transform way of doing this but the ACPU is
easier to use). Do let us know how you printed out the patch set. As
Graeme noted in his response, it's more likely a workflow issue.
One other observation, using -g128 is overkill IMO. I routinely use -g51 in
the final patch set (I do a precondition profile first to establish a
preliminary profile).

Subject: [argyllcms] Dark colors and very poor gray scale after printer
profiling
Hello,
I've recently bought a used eye one pro, I' ve used it to calibrate my pc
monitor and to read 1764 patches.
I've printed with my own created icc profile, with the icc of the paper
manufacter, as well with the standard icc profiles of my epson printer but
none of them seem to work.
Except from little variations among the profiles, the printed colors are
much more darker and the gray scale is very poor from the soft proofing on
Photoshop. Some image parts with gray shades are printed black!!
The Argyllcms commands that I used to generate the profile are:
1) targen -v -d2 -G -g128 -f1764 eye_one_result
2) printtarg -v -ii1 -R1 -T300 -p A4 eye_one_result
3) chartread -v -H -T0.4 eye_one_target_result
4) colprof -v -qH -r1.0 -D"Polyester MatteBlack FineArtMattePaper"
eye_one_result
5) profcheck -k eye_one_result.ti3 eye_one_result.icm
Profile check complete, errors(CIEDE2000): max. = 1.617668, avg. = 0.349918,
RMS = 0.398709
Do you have any ideas why is this happening?
Thanks in advance.
Greetings from Munich,
