What Is PDF/X?
PDF/X is a strict subset of PDF built for printing. Here is what makes it special.
Quick answer: PDF/X is an ISO standard for print-ready PDFs — it forbids things that break printing, like missing fonts or external links, so a press gets exactly what you designed.

When you need it
Professional print shops often require PDF/X for books, brochures, and packaging. Everyday sharing rarely needs it.
