New downloadable packaging specifications from GWG

In packaging, features such as support for live transparency in PDF files and support for multiple layers are important and necessary. In the versions of PDF/X supported by the Ghent PDF Workgroup (PDF/X-1a:2001 and PDF/X-3:2002), those features are not supported. Therefore, the first set of packaging specifications are not PDF/X compliant. However, the ISO plans to release PDF/X-4 in mid 2007, where transparency and layers will be allowed. The Ghent PDF Workgroup will use this new ISO standard in the next version of its packaging specifications.
