I use Acrobat Professional to both scan, OCR and optimize PDF's. It
works very well. I do this for many vintage manuals that had been
previously scanned that I've downloaded that have not been OCRed or
optimized. BTW: OCR works best when the manuals are scanned for color
or grey scale at 600bpi or better.
