Steve,

I should wait for the extended report but:

The limitation on 55% is because your Dmax is reached there 
and no increase above ?
What about detail above that patch, does it still hold ?
A more theoretical question, if an ink reaches Dmax at 55% 
isn't that an unbalanced distribution on that particular 
printer ?  In other words aren't you cutting off one droplet 
size etc ? This is for the black, it could be good for color 
saturation though. If the inks behave more like dyes one 
wouldn't expect a Dmax limitation that low.
