Proofreading is the very last step before a document is published online or goes to the printer. Due to time constraints, this crucial step is often omitted. We highly recommend that you schedule it in at the very beginning of your project.
Proofreading is a final check after typesetting to ensure that there are no typos or layout issues in the document. The proofreader carefully goes through the whole text to confirm that there are no spelling mistakes, typos or missing punctuation marks, there is no text that was omitted during the typesetting phase, and that dates and names are all correct. It is always carried out by a qualified, native speaker proofreader.
