Sounds like you may have printed the target incorrectly.

If you don't have color management turned off when you print the target,
it will print already profiled (which also happens to be too "light",
vs. what the uncalibrated target print would be like).

If you then build a profile from measurements of this target, the profile
won't do much.

If you then use that almost-do-nothing profile and print through it
"correctly" in Photoshop (with color management now disabled in the
driver), the prints will be too dark.

Look at your target print on EPG vs. the matte papers. It should have the
same "look", dark, saturatd, etc. If it looks too "good", then that's another
sign that it's not printed correctly.

My guess is that you'll need to print this target over (and then throw out
your measurements and do them over again, too)...
