Yet another example of your inability to write what you mean. Do you see
the difference between what you are quoting from 4/4/05 and the much more
specific way you specify refreshing the pen used for the upper layer at the
same point that the pen for the lower layer was reinked? In case you don't,
"discernably differ" can refer to a lot of different parameters other than
the refreshing point of the pens used to draw the two supperpoed lines.

Ipse Dixit. Why would the starts and stops of the underlying layer "almost
certainly ... protrude beyond the black"? And if so, by what measure; that
is, what is the width of the amount of underlying layer that "would protude
beyond the black" on either (or each) side of the black line?

Again, ipse dixit. Why should the scribe need a low power microscope to
detect the start/stop point of any portion of freshly laid down yellow
lines?

But you haven't established that the VM shows evidence of the latter, as
opposed to the former.

Do try to keep up with the thread. Dr. Towe has quoted an e-mail from
Enterline in which he disavows the whole proposed scenario of reinking
followed by subsequent cleaning. See: http://tinyurl.com/3zm9r

Indeed. See the link added above to Dr. Towe's post.
