A reader was working on optimising PDF files and came across a term that she hadn't seen before, JBIG2. Acrobat's built-in PDF Optimizer utilises this smart codec to reduce file sizes dramatically.
There is so much going on behind the scenes of these massively powerful programs that knowing which option does what, and which to avoid is getting more complex. JBIG2 (lossless) is an excellent codec for use when the image quality of black/white scans and reducing file size are both important.
The default quality is Lossy - make sure that you choose lossless.
