Abstract In order to enhance the novelty of experiment courses, optimize the design of experiment classes and cultivate the comprehensive abilities of students, experiment teaching activities that integrate fabrication of photosensitive coating, exposure, development and fixing have been established based on photosensitive imaging of thionine. The principles of sensitization and imaging of this photosensitive system have been introduced. The results of photosensitive imaging have been displayed. The content, arrangement and effect of this experiment teaching have been systematically presented. Transfer of digital images to photographic paper by utilizing light and chemical reactions and combination of basic theories, experimental phenomena and feedback contribute to the creativity, interestingness and competency development orientation of the experiment teaching activities.
