@Paddy, A printed copy of your PDF is not a very good test of document quality. Embedded BMP representation within LibreOffice is at 300dpi. Export print may be the vector format (wmf, emf, eps, svg) or a bitmap rendering preview--at 300dpi. You really need to open each PDF in suitable viewer and zoom in to 800% or 1200%. How do embedded images compare there? Are they bitmap? Or more concise full resolution vector images? Also, the platform you work on will impact handling of vector images. Several helper programs are needed--Ghostscript, ImageMagick, pstoedit and the mix will impact handling as bitmap or vector. Please provide your OS details, and perhaps attach a sample output (via the Nabble interface).
