I don't know, but that's not what I would do.

First, there may be no "excess" of density in any absolute sense.  It might
actually be an improvement.  

The 50% density I make the curves to is simply based on consistency with the
systems I've used in the past.  I started with the Piezo system and have
continued to match the average midtone densities that I was getting from
that old system because that's what my files were made for.  However, what
is the ideal 50% density, if any?  I think the old Commission Internationale
d'Eclairage, or "CIE", that made the L*a*b* system for measuring luminance
and color may have been the most sophisticated, empirically-based study I
know of.  In their Lab scale "L" is the measure of luminance with black = 0,
white = 100.  In the Luminance channel, the standard 50% I've been targeting
is arguably too light, at L = 56.  The next darker patch is closer to L =
50, which some might argue is where the 50% patch should lie.  When I
measure my old Kodak "Gray" card, the spectrophotometer says its Lab
luminance value is 50.

The bottom line is that the slightly darker 1290 prints that are made with
the UT2 inks and 1280 curves are arguably closer to having midtone densities
that are consistent with some widely-recognized standards.

Second, the real practical issue is whether the monitor matches the print.
Monitors appear to be rather inconsistent in this respect, and most of us
probably use some method to adjust or calibrate the monitor, perhaps as well
as the view in Photoshop, so that the monitor image more closely matches the
print. It may well be that monitor manufacturers, however, attempt to match
the Lab or some other recognized standard, but I really don't know.

So, don't worry about the slightly darker prints of the 1290 compared to the
1280.
