I don't know what software you're using, but I would advise never EVER using 
pdf2djvu, or the Win32 version "pdf2djvu GUI" for scanned documents; it's 
actually worse than doing nothing! All it does is shrink the source file to 
100dpi and run wavelet compression on the result. This is NOT a real DjVu file.

The only Windows software even worth looking at, in my experience, is the 
original Lizardtech "Document Express" software. It's not as tweakable as the 
stuff I'm working with (which requires a *nix of some sort), but it's much 
faster and it produces results that are quite good. It is, after all, the same 
program the professionals use.
