It consists of a thorough revision of the text, during which three fundamental tasks are undertaken:
— The cleaning gets rid of mispellings, orthotypographic mistakes or any other element that hinders reading comprehension.
— The normalization corrects the mistakes according to the grammatical and orthographic rules that have been agreed on with the client.
— The unification is used where no specific rule exists or when several rules may be of application. This includes different typographic resources that are common in texts: bolds, italics, quotation marks, capital letters, etc. During proofreading, special care is devoted to the unification of the text.
