Proofreading consists of comparing one version of a text—often the final layout, or proofs—against a previous draft to ensure that all the edits have been entered properly. In publishing, this may include:
- identifying and correcting discrepancies between versions that were overlooked by the author or editor;
- checking layout, formatting, and typography;
- testing links on ebooks, websites, and other online publications;
- and reviewing color separation, image quality, and other details in preparation for printing.
The tasks above are based on those listed in the Editorial Freelancers Association Code of Fair Practice, 3rd ed.
