Since 1988, Supon wrote and produced books on graphic design related subjects, which were published by industry giants such as Rockport Publishers, Madison Square Press, and Books Nippon. As a graphic designer foremost, Supon knew what he wanted in design publications. His first book, International Logos & Trademarks, sold out within months.

To date, over three dozen titles have been published under Supon's name. There also have been five books that promote his work. Currently, Supon is working on a new book.
