Scribus

Scribus is the open-source page layout tool for work destined for a printing press: proper CMYK color management, spot colors, bleeds, and PDF/X export that print shops accept. Newsletters, posters, zines, books — it does the InDesign job for people who can’t justify the subscription, and 1.6.x stabilized years of development into a usable modern release.

It can’t open InDesign files at all (IDML import exists but is rough), master page and style tooling is clunkier than InDesign’s, and long-document features (cross-references, advanced footnotes) lag. The text engine improved but still frustrates typography perfectionists. For screen-only design, honestly, Inkscape or Canva-class tools are faster; Scribus earns its keep when ink meets paper.
