Publishing PDF files whit PDF/X-4 compatibility for professional printing
PDF files for professional printing are high-quality reproductions of your publication that are passed to a print partner (normally external to your company). You'll typically require a CMYK document, printer marks, bleed, >300dpi images, and PDF/X-1a, PDF/X-3 or PDF/X-4 compatibility (for CMYK output).
Affinity Designer 2 can do it!
