A short history of the GWG
![Page 7: Digital printing v4 - Ghent Workgroup · 2019-05-02 · Digital Printing ElliCloots& David van Driessche Senior Product Marketing Manager, EFI & CTO, FourPees ViceChair & Executive](https://reader036.vdocuments.net/reader036/viewer/2022070905/5f73f733e06eba0db72a5296/html5/thumbnails/7.jpg)
Mission Statement
To establish and disseminate process specifications
for best practices in graphic arts workflows
![Page 8: Digital printing v4 - Ghent Workgroup · 2019-05-02 · Digital Printing ElliCloots& David van Driessche Senior Product Marketing Manager, EFI & CTO, FourPees ViceChair & Executive](https://reader036.vdocuments.net/reader036/viewer/2022070905/5f73f733e06eba0db72a5296/html5/thumbnails/8.jpg)

Key points for the GWG specifications
• All based on PDF/X– PDF/X-1a for the older specifications– PDF/X-4 for the current ones
• More ”targeted” than PDF/X– PDF/X is a global graphic arts standard– GWG specifications come in variants
• For market segments• For different use cases• For different printing technologies
