(re: re: re: Kinko’s scanning) I’d have to agree with Ken on the ‘getting boring’ bit…. I scanned a 195 page service manual (glue bound spine) using a flatbed scanner. Took me quite a few hours just to scan it. Then I spent around 3 times that amount manually cleaning, touching up, despeckeling, cropping and making minor rotation adjustments to each of the pages. Finally, I pushed it through a PDF generator and popped 20Mb worth of files! It was a very very dull process!
Given the type of content, I didn’t scan anything over 150dpi but given the nature of the ‘magazines’ it would be prudent to scan them at 300dpi or more in order to maintain the source definition. However, I think a single A4 (sorry, didn’t know size of letter!) page scan saved in a [raw] format would be around the 25MB mark (for 300dpi). PDF does do some processing on the image but I think you’ll need a decent generator (Adobe’s) in order to have full control of the process. I don’t know the PDF specs at all so I don’t know if you can choose/force the compression algorthim (lossy/not).
Best of luck!
