This article explores the artistic characteristics of contemporary Chinese character posters from the perspective of Roland Barthes’ semiotics. In the process, the method of work exposition and case analysis is used, and the artistic interpretation is combined with historical, social and cultural factors. Through analysis, it is concluded that Chinese character design is the “content symbol” of posters, Chinese character posters are the “visual representation” of Chinese aesthetic paradigms, and the contemporary artistic expression of Chinese character posters. The article proposes that Chinese character posters will exist and develop as independent works of art in the Chinese design environment. Chinese character posters will also become an important link between China’s cross-cultural communication and Chinese character culture, integrating multiple factors such as culture, art, concepts, and politics.
