校正

Also known as proof, proof-reading

Proofreading is a phase in the process of publishing where galley proofs are compared against the original manuscripts or graphic artworks, to identify transcription errors in the typesetting process. In the past, proofreaders would place corrections or proofreading marks along the margins of printed text. In modern publishing, material is generally provided in electronic form, traditional typesetting is no longer used and thus (in general) this kind of transcription no longer occurs.
