Is there a option or preference to not update the pdf version when saving. We use Acrobat 6 on OS 10.3. When opening 1.3 or 1.4 pdf files we need to maintain the version after saving. Now the files are being updated to 1.5 which will not work with our rip. I currently have to print a new postscript file and redistill if I make changes to the pdf. I thought I saw an option for this but now cannot find it.
