Good advice, you can use Paint Shop Pro to do this kind of thing as well, at lower cost (i.e. free) paul baker http://www.321books.co.uk -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Smiley-Oyen, Paul Sent: 07 January 2004 15:13 To: [EMAIL PROTECTED] Subject: RE: [PDF-Basics] scanned imports too big PDF-Basics is a service provided by PDFzone.com | http://www.pdfzone.com/ __________________________________________________________________ Have you tried testing the output quality with grayscale images? Unless you are working with multi-color images, you should be able to convert the mode of the scanned files to grayscale... That is, if you have Adobe Photoshop, or another program that can convert the mode. This should make your files much smaller. If you still need smaller filesizes, determine if you can use one of the 'lossy' schemes of file storage like .jpg.

Hi Bob, you should try our PDF compressor-it should significantly reduce the size of the scanned images, without loss in quality. I don't know about the exact compression ratio but we have a number of clients who scan CAD images and use us to compress them. There is a demo version @ www.cvisiontech.com. max To change your subscription: http://www.pdfzone.com/discussions/lists-pdfbasics.html To change your subscription: http://www.pdfzone.com/discussions/lists-pdfbasics.html To change your subscription: http://www.pdfzone.com/discussions/lists-pdfbasics.html
