Publishers will be familiar with the colophon, an inscription at the end of a book with information about its production, such as the designer, typeface, cover artist, and printer. The other usage of “colophon” refers to a specific mark that might be embossed or printed on the title page, the spine, or book jacket to identify the publisher. For example, the colophon of the Penguin Random House publishing company is an illustration of a penguin inside an orange oval. “Colophon” comes from the Greek “kolophōn,” meaning “summit, finishing touch.”
