It seems somewhat unproductive to rescan these documents simply to downsample them - you could also consider using Enfocus Pitstop to downsample this document - do you happen to know if the scans are greyscale or bitmap ? You could also reduce the file size by converting from greyscale to bitmap if this is the case...also using Enfocus Pistop .. You can even try it before you buy it ! http://www.enfocus.com/products/overview.php?nr=3 - there are action lists you simply can download and use. http://www.enfocus.com/support/actionlistlib/showactionlist.php?id=68 There is a small issue depending on the size of the type and the style of the type, you may find it more difficult to read if you downsample or re-scan at this lower 300 ppi resolution. I created a few examples for you to examine - these small PDF files have 12 point, 6 point, 3 point and 1 point type in both serif and san serif. They are as follows; http://www.jahn.org/examples/GSres600.pdf http://www.jahn.org/examples/BMres600.pdf http://www.jahn.org/examples/GSres300.pdf http://www.jahn.org/examples/BMres300.pdf GS is Greyscale and BM is Bitmap Note you can read the 1 point type at 1200 percent magnification on the Greyscall 600 ppi example - it is much more difficult to read it as a bitmap (black or white pixels only) and it is impossible to read the 1 point type at 300 pixels per inch at any magnification Hope this helps. ===================== Cheers, Michael Jahn 1104 Esplanade Suite 102 Redondo Beach California 90277 Home office : 310 540 6950 Cell : 617 388 5615 Lat: Deg : Min : Sec 33 : 49 : 31.195N Lon: Deg : Min : Sec 118 : 23 : 23.334W ===================== To change your subscription: http://www.pdfzone.com/discussions/lists-pdf.html
