Cley, I appreciate your comments. I don't know much about the various PDF formats and don't know how I ended up with that format. For some reason I guess at some time I thought it was the best generally readable format. I notice if I uncheck that format it jumps to "Create PDF Form" with 4 format options. Since I'm not making forms it seems as if that isn't the best option. Tagged PDF seems to be the only option left. Is that the recommended format? The help implies that the fonts are only imbedded in PDF/A-1a so does that mean that someone opening a Tagged Format PDF may have problems if they don't have the same fonts installed? I thought that wasn't supposed to be the case. In testing I have just done, the PDF/A-1a came out as 89k, Tagged - 83k and "Create PDF Form" using the PDF format ended up as 67k. I normally am looking for the smallest size so as not to burden people with slow access speeds. All three are readable in Acrobat as well as Preview on my Mac. There's no way I can know what reader everyone will be using if there are any issues any more. Any further comments are welcome.
