[EN] Use of Object compression

What is it all about?

Since PDF 1.5 some objects in pdf-files are allowed to compressed collectively. This technology is being used in this pdf version. However some pdf/x standards that are compatible with pdf 1.4 only allow for objects. Object overlapping compression therefore not allowed in the standard of the following pdf/x files:

  • ISO 15930-1 (PDF/X-1a:2001)
  • ISO 15930-3 (PDF/X-3:2002)
  • ISO 15930-4 (PDF/X-1a:2003)
  • ISO 15930-6 (PDF/X-3:2003)

An object overlapping compression is allowed in this pdf/x standard with pdf 1.5:

  • ISO 15930-7 (PDF/X-4 und PDF/X-4p)

How do I avoid this error?

We recommend to download the DUON joboptions which can be found on the site www.duon-portal.de under the left header Help & Download.

Please make sure that the setting „Create Tagged PDF“ is deactivated!
