Effective educational communication of culturally dense decorative motifs in screen-based educational materials was treated as a continuing design challenge in digital education. This study aimed to establish and validate a design framework that supported the translation of traditional decorative motifs into clear and teachable information-visualisation posters for educational communication. A qualitative, design-oriented methodology was applied through semi-structured expert interviews, grounded-theory coding with Open Coding, Axial Coding, and Selective Coding, comparative poster design, and expert review using timed first exposure and a follow-up group interview. The interview analysis established four design dimensions, namely Consistency & Distinction, Adaptability, Multisensory Integration, and Emotional Engagement, and these dimensions were generalised as traceable design commitments for educational visuals. Two comparable posters were produced for the same motif extracted from illustrations in “The new diagram of Confucian imagery”, with one poster guided by the framework and the other developed as an intuition-based baseline. The expert review showed that the framework-guided poster was interpreted as having a clearer hierarchy, easier identification of key educational content under time pressure, and more stable visual coding than the baseline poster. The analysis also showed that the framework improved the explainability of major design decisions by linking these decisions to explicit criteria rather than personal preference. The results were applicable to researchers and practitioners in information visualisation and visual communication who developed educational resources for cultural knowledge dissemination in multimedia educational environments
