Just to step in and say something here, with all of this talk about
printing targets through profiles and rendering intents.....!

You -don't- print targets through a profile. (It's physically possible,
but this is not how you use a target, or the purpose of printing a target).
And likewise, since you're not printing through a profile, there is no
rendering intent to affect things.

The target is meant to be printed -without- a profile; with all color
management disabled. When printed this way, the target print represents
the uncalibrated (unprofiled) state of the printer, and what you get, and
measure, should be based only on:

- The printer you've used

- The inks in that printer

- The print quality and media setting that you've chosen in the driver

When you print the target this way on Museo Max, on the 9800, what you get
will represent the darkest black and the most saturated primaries that will
be possible to achieve on that combination of printer, paper, print quality
setting and driver media setting. This is -before- profiling.

If the target print, this way, gives you a weak black, and/or muddy primaries,
there's nothing any profile can do to fix that. You can't boost what isn't
there to begin with, and the target, printed as described above, shows you
everything that's "there" to begin with.

If there are problems getting a "good" print of the target this way, then
the only wy that this can be "fixed" or "improved" is by adjusting the print
quality and media settings, directly in the printer driver (in this case,
the 9800 driver).
