not to be a stickler here, but a question for you....

I know when you scan large format engineering drawings on a drum-type
scanner there is always some concern that your final 'image' is a bit
distorted due to the drum and the distance between the substrate and the
'lens'.

When you encapsulate them in mylar for scanning, do you exacerbate this
distortion?

We had engineers/draftsmen do dimensional take-offs on some of the source
materials and then compare them to output from the scans and they found
discrepancies.  The decision was made to include a scaling element on each
source item when they were scanned after the first few tests were run.

I'd guess on a flatbed scanner, this would be less of an issue.
