>Why thicker glass, Paul?

It looked like the center and edges of the print were not getting the same
amount of PUR.  I thought that could be from the 1/4 inch glass, which was
on a towel and supported by particle-board, might be sagging or otherwise
not being totally parallel to the rod.  I think Diversified's literature
indicates that the set-ups they sell use thicker glass.  On the other hand,
it could be that a 1/2 inch rod is not sufficient to span a 16" print
without bending slightly.  Unfortunately, the thicker rods get expensive.

Diversified also has a pad that can be put under the paper.  I think the
"softness" of the support is a variable that might need to be explored.  As
I understand it, these long rods are not usually used on hard surfaces.  I
think the medium is often dragged across the rod with a flexible web.

I didn't do a lot of  experimenting with 16x20 prints.  I tried a few, was
not satisfied with the results, and ran out of time to do more.  I think the
rod & PUR deserve more work, but I just have not had the time for some
months.  A thorough search of how industry uses them might give some hints
as to what is needed to get good results.  Robert probably has the most
experience with the rod and large prints, so searching his posts would also
be a good idea.
