Due to the unique requirements of files designed for packaging, the Ghent Workgroup felt that it was best to create a separate specifications document for packaging as opposed to simply including packaging as a variant of the GWG 2015 Specifications. That’s why we created a document that details the use of the GWG 2015 specifications as they specifically relate to packaging.

This document describes the requirements that a PDF must comply with to follow the GWG2015 packaging specification. The GWG2015 packaging specification is a specification built upon current ISO PDF/X standards (PDF/X-4) but adds a number of specific requirements for different market segments.
The GWG2015 packaging specification allows for some deviations from the PDF/X-4 standard in order to better meet the unique requirements in packaging printing that cannot be met through strict adherence to the standard.
