Check twice, print once. This rule is extremely important in the publishing industry, since you cannot replace text by simply clicking the “edit” button as you would do on a webpage. Therefore, proofreading plays an important role when preparing various texts for publishing, starting from a business card and ending with a book.
Proofreading means correcting small spelling, punctuation or text formatting mistakes. It can be compared to checking the text with a spell check function in order to make sure that the letters and commas stay in their right place, the abbreviations are correct, etc. However, it is not an automated process, as only an experienced professional can spot inaccuracies in the text and understand its meaning, context and make the necessary corrections without losing the original idea.
