-- 400 - 600 dpi b&w Group 4 FAX encoded TIFFs these can be converted simply to pdf's with Eric Smith's "tumble" program. I've scanned 1 million + pages with this encoding using a Ricoh IS520 double-sided 30ppm scanner at 400dpi. All of the documents at bitsavers.com/pdf are processed this way now. Pages with graphics are scanned as 100-200dpi JPEGS but normally the text requires a bit of contrast enhancement on these pages. tumble handles mixed JPEG and TIFF documents.Received on Mon Dec 15 2003 - 14:39:33 GMT
