Thanks for all the good replies.  Taken together they would seem to go
along with my observation of the BO prints acheiving continuing
gradation past the point where full coverage begins.  Perhaps dmax can
be increased with greater ink load (assuming the 2nd ink isn't too
light) up to a point.   If some papers can handle more ink than others
before that point is reached, it would explain the seemingly
conflicting results reported here. All very interesting, thanks.

Clayton
