Thanks Roy.  I seem to have something else going on when I try to
measure.  Everything is all blocked up beyond 70.  I'm going to start
over.  I can see different densities in the print out all the way to
100 but not in photoshop.  Must be my scanner.  I'm using Vuescan and
it's a raw scan with nothing added but that has to be it.  Shouldn't
be the monitor as it's calibrated.  I'll play around some more tomorrow.
