How do I ensure that the production PDF is the right press quality I need?

The PDF produced by eDocBuilder is the same PDF that you input, with text and image objects added according to the file. There are no distiller settings to make (which is what is meant by "press quality modified") because eDocBuilder is a completely PDF based workflow -- there is no distillation happening at all. We also do not modify the Acrobat version; if you save your master PDF as pdf 1.3 then the output file will be PDF 1.3.
