Attached is a .PNG portion of a scan. It was a B&W (two-tone, not all grayscale) and it looks very speckly and just dirty.

Does anybody have any tips about how to make text scans like this look better? Thanks as always.

(Nevermind the attachment. When I hit "Attach This File" it didn't do anything at all. So here it is from Photobucket.)

"Filter/Blur/Gaussian blur" (9px) followed by "Filters/Enhance/Unsharp mask" (3.7/5.0/0.0) gives surprising good results for the effort:

But a grayscale scan could have looked better and would have given you more data for any post-processing.

Thanks again, OfNuts! I'll work with this and, for the future, I'll make sure to get grayscales.
