InDesign 2026 PDF Package Export Rasterizes Illustrator Vector Files (PDF/X-4) on Windows and macOS
I am experiencing a reproducible issue in InDesign:
-
A pure vector AI file (barcode) is placed and linked in the document.
-
When exporting the PDF via File → Export using PDF/X-4 or similar, the AI graphic remains fully vector-based.
-
However, when creating a PDF using File → Package → Create PDF with the exact same PDF preset, the AI graphic is rasterized and becomes an image in the resulting PDF.
Expected behavior:
The AI file should remain vector-based in both export methods when using the same PDF preset.
Question:
Does the Package → Create PDF function use a different internal export engine or rendering process compared to the standard Export workflow?
Is this a known regression in recent InDesign versions?
