Proofreading is the reading of a galley proof or an electronic copy of a publication to detect and correct production errors of text or art. Proofreading is a critical part of the writing process that involves English experts scrutinizing a written document in order to identify and rectify grammar, punctuation, spelling and vocabulary errors. Good writing always involves modification and revision, and proofreading is a fundamental part of this process. People need proofreaders in order to be sure that their work does not contain any mistakes.

Editing (also copy-editing or copyediting, sometimes abbreviated ce) is the process of reviewing and correcting written material to improve accuracy, readability, and fitness for its purpose, and to ensure that it is free of error, omission, inconsistency, and repetition. In the context of publication in print, copy editing is done before typesetting and again before proofreading, the final step in the editorial cycle. 

Copy editing has three levels: light, medium, and expert. Depending on the budget and scheduling of the publication, the publisher will let the copy editor know what level of editing to employ. The type of editing one chooses (light, medium, or heavy) will help the copy editor prioritize their efforts.

Calibration to confirm the coloring, in particular, is also called color proofing (color school).
