At the end of a book or text, there is a section containing various descriptive information such as the author’s identity, a presentation of the work, details about the publisher, and the printer, including the date and place of printing. Sometimes, this section is associated with a particular symbol or the printer’s signature. Although the word “colophon” was once used, it is less common today and more often reserved for older works. In advertising and other contexts, the expression “printed copy” is generally preferred.
