Hello Tyler,

>Clayton, I'm not sure where this idea of full coverage came from. 

It was just my observation of BO prints that, viewed with a loupe, the
specs of paper white disappear completely at around 95%, meaning that
the dots are close enough to fully overlap.  I was making the point
that even though full coverage begins at 95%, there is still
increasing visual density as the ramp moves toward 100%.  I assume
this is due to the dots being continually placed closer together,
which would mean greater overlap, which means more ink is being laid
down.  This would seem to support the idea that increasing ink load
increases visual density.  It doesn't have any significance beyond
that.  It's just the point at which there is no more uninked paper
showing.

Regards,
Clayton
