Hi Peter..
I've read the responses so far.. This is certainly a tuff piece from what I can see.. So two question to help me understand a bit better.. How large is the original which I understand you can rescan and what is the max real resolution you can throw at it without interpolation..

Subject: [Digital BW] Moiré problems

I am trying to print a copy of a 19th century wood engraving -- you can
see the image on this page: http://www.marquis-kyle.com.au/mt/002036.php

The fine near-parallel engraved lines produce disturbing moiré patterns
in the print in areas of similar tone, such as in parts of the sky. The
same problem, in more extreme form, can be seen in various
magnifications of the zoomify image on the web page.

Can anyone here give me some ideas for processing the image to avoid
this problem in the print, while retaining as much detail as possible?

I'm using Photoshop CS6 Extended to make a gray scale TIF, for printing
on an Epson R2400 on Hahnemuhle PhotoRag via QuadtoneRIP.
