Hi, I just thought I would post an update.
I am now specifying my fonts via FOP and the result has been remarkable. A 5 page PDF with one embedded font is now approximately 200K! I could not of hoped for a better result. As an aside, I have encountered a number of issues with FOP not picking up my fonts unless installed but I will get some concrete use cases before I post regarding this. I am running on Mac OS X 10.5 so maybe this is contributing to it. Finally thank you for your help it is much appreciated. Regards Lea.
