Hi
We're creating pdf versions of engineering drawings for our released copy archive.
Most are output to Acrobat from several CAD apps. 
Some of these are scanned hand-drawn vellums, tho.
We scan the 11x17 B-size ourselves on an old Ricoh IS410 bed scanner inputting 
CFM-Twain at 300 dpi in scanmode halftone set to error diffusion. The resulting pdf 
files (single sheets) are coming out at 2 and 3 meg. Unacceptable with the number of 
files we have to store.
Anybody know how to do this and get smaller files with a decent image?

Also we're having our larger hand-drawn vellums done by an outside repro house and 
they're doing a tiff scan import that's generating filesizes of 300k to 400k. I'm used 
to seeing 40k or 50k come from our CAD programs. What can I tell the repro house to 
help get their file sizes down?

Thanks in advance for your help
