    Us e Acrobat 4 (PDF1.3) all the time?

      My boss has instructed me to always save my files as Acrobat 4 or PDF 1.3 as it appears in Illustrator. My purpose for making these PDFs is to send to customers so they can see a layout and approve it, no editing required.
      My question:
      Given this purpose, will I ever get someone complaining that they can't open a PDF I send if I use Acrobat 8 (PDF 1.7) the most recent?
      Adobe reader is a free program and anyone can update to it. Why should I downgrade for those one-percent-ers?
      In the same line, why should I save as a higher version? What do I get?
      I'm a little confused with these version numbers, so I usually leave it at whatever default shows up, usually Acrobat 5 or 6.
      Help me out.

          Certainly, if they don't have Adobe Reader 8.

          1. Because your boss says so, which might or might not matter.
          2. Because not everyone is permitted to upgrade their software. In
          corporate settings you are frequently stuck with what the company
          decides.
          3. Also some people might use different PDF viewers with different PDF
          version support.

          Each new version of Acrobat has a new version of PDF, as you have
          probably recognised. Each includes new features that are allowed (but
          might not appear) in a PDF.

          Example of new features:
          * PDF 1.5: JPEG 2000 compression. Effect of using this with Acrobat 5
          or older: error message, blank areas or pages.
          * PDF 1.7: PDF packages. Effect of using this with Acrobat 7 or older:
          looks like a one page PDF with attachments.
          * PDF 1.4: document metadata in XML format. Effect of using this with
          Acrobat 4 or older: none at all. Information is also included in an
          old format, for compatibility.
          There are hundreds, if not thousands, of specific features.
