Magazine Photo Scans & Interference Patterns

[JamesWilson]

HELP!

I'm trying to scan some old black & white magazine photos and find that the little dots seem to interact with the scanner processing to create very bad intereference patterns:

Is there an easy solution to this? I've tried various resoultion changes but haven't had much success....

TIA

Moire pattern. Change the expected output to B&W, "document" settings?

Kinda depends on which scanner you have and the software capabilities.

Thanks... I'll try that and see how well it works out.

Not all scanning software has the feature to remove it. Epson has a mode called "descreening" that works pretty well at 200dpi. Google "descreening scans".
