Dave Zwang, chairman of the Ghent Workgroup (GWG), has published a two part article on the state of standardisation of packaging workflows on whaththeythink.com. The first part covers the definition of spot colors using CxF (Color Exchange Format). The standardisation of non-printing information (e.g. die cutting, varnish, braille) in packaging files using meta data in optional content groups (layers) in PDF is the focus of the second part. On the iniative of GWG both topics are currently integrated into upcoming ISO standards.
