After nine years of (hard) work the ISO has published PDF 2.0 as ISO standard 32000-2:2017. This is the first PDF specification which was completely developed by more than 30 PDF experts from all over the world in an ISO working group. ISO 32000-1:2008 was basically a takeover of PDF 1.7 from Adobe. PDF 2.0 is more an evolution than a revolution. An important goal was compatibility to older PDF versions.
Seven chapters of the specification (971 pages in total) have been completely rewritten (e.g. transparency, tagged PDF). The goal was not to introduce new features but to eliminate ambiguities and errors of old specifications.
- Setting to activate black-point compensation (BPC) for each object. This allows to define predictable color conversions.
- Output Intent per page (optional). E.g. Coated for the cover pages and Uncoated for the body pages of the same PDF.
- Use of spectral data for spot colors (using CxF/X-4).
- Definition of the printing order (e.g. for sheetfed offset).
- Enhanced halftone features (origin, halftone dot shape).
