RE: Plans Enlargement
Be very careful if using any kind of heat, like an iron. It may cause more damage to the paper than expected. Regardless how "folded" they are, I would tend to discourage using heat. If you can get the drawings scanned locally, you can email them to me. Have them scanned at least 200-250 dpi, in TIFF format. Don't wory about any folds or other imperfections because they are of no concern at all. I can digitally clean up the TIFF files for you and email them back. After that, it's your choice for printing sources.
