Signature is the most rational and organized combination of symbols and logotypes, which are the basic elements of the UI system. It represents the official notation of the University of East Asia and is the most direct means of recognizing the University of East Asia externally. Therefore, the scope of utilization of the signature, including various public notices, forms, and printed materials, can be varied depending on the circumstances of the media in which it is applied. The Signature System was developed to enable this to be used systematically and effectively according to its functions and applications.
