NCA is what Epson uses to base their own canned profiles upon. It works in
many cases, not in others.
If you are using 3rd party Epson papers, all bets are off. The driver
settings for specific papers as you know affect the outcome. But even with
Epson papers, usually NCA works pretty well. The benefit is a larger color
gamut from the printer. The downside is you lose a good deal of the tonal
data in the darker regions. If you use one of the automatic settings and
lock it down, you get better tonal detail but lose a good deal of the color
gamut.
In the 2200 and 9600, there is an ink limiting slider. It works somewhat
well but again will lower the color gamut. So there is a fine line to ride
here.
Epson American is well aware of the need for a better NCA behavior in the
driver! It's up to the people in Japan who write the software driver to
incorporate this. I and others on this list have had countless meetings
discussing this with many of the engineers and I think they see the light.
When such a driver will appear is anyone's guess.
