An issue passes through many hands before it reaches readers, and small slips such as an uncleared photo, a missing bleed or a wrong ISSN are costly once the press has run or the digital edition is live. This checklist follows one issue from planning to the archive: content and schedule, rights and permissions, proofing, print-ready PDF files, the digital edition, metadata, distribution, promotion and archiving. Where an item refers to a standard (PDF/X, ICC colour profiles, ISSN, WCAG, PDF/UA, PDF/A), the help text links to an official source. Printers, distributors and platforms set their own requirements, so their written specifications take precedence. This is practical guidance, not legal advice: for contracts, licences, labelling and legal deposit, check the rules that apply in your country.
