It's not scanning quality, it's image compression.
I meant generally speaking.
I replied to you because it only vaguely touched the issue of low quality digital goods. I understand that the pdf can't be more than a few megs, but most of the times the images are really blurry and overall it looks shitty. It absolutely can't be a substitute to actual manuals.
Ok, rarely happens with new games, but then you'd be happy if you get a decent digital manual at all.
