I have a large PDF document that consists of scanned pages of a textbook. I want to run Adobe Acrobat 9's text recognition function on it, but I'm presented with this menu when I do.
I'm confused by the options in the highlighted menu. What option will produce the highest quality/most readable text? I thought 600 dpi implies a higher quality image than 72 dpi, so I'm confused by "High (72 dpi)" and "Lowest (600 dpi)."
