Try placing a dark piece of paper behind the scanned object.  Black is
recommended, but you may need to try other dark colors, depending upon the
color of the ink.

| of documents
| written in dark ink on very thin onionskin paper.
| Consequently there is a
| bad "bleed-through" problem, i.e. writing on the verso can
| plainly be
| seen. This results in nearly illegible text. Does anyone
| on this list
| know of any trick, such as a mask or filter, that can
| reduce or eliminate
| this problem? I should add that the original mss. present
| the same
| problem, so any solution would in effect be improving on
| the visual
| quality of the originals.
