Application Notes

Developed by ISO TC130 WG2/TF2 (PDF/X) the goal of this document is to provide information that is supplementary to ISO 15930-9, to further assist with the successful implementation and use of tools and workflows that comply, and take full advantage of, the PDF/X-6 standard. This document focuses on the key differences between PDF/X-6 and its predecessor, PDF/X-4, and is not a substitute for the full standard, which is available for purchase from APTech.
