The widespread adoption of digital media is transforming the creative processes, forms of expression, and dissemination channels of paper-cutting as an intangible cultural heritage. As a national-level intangible cultural heritage, the art of paper-cutting currently faces practical challenges such as a generational gap in transmission, limited dissemination channels, inadequate digital design capabilities, and lagging database development. This paper adopts a framework centered on preservation, presentation, and dissemination. Integrating research practices in digital preservation, symbol library construction, and innovative design, the study explores two key areas: dissemination strategies and innovative design. Regarding dissemination strategies, it proposes two approaches: creating a dissemination matrix through multi-platform collaboration and ensuring cultural integrity to safeguard the authenticity of the craft. In terms of innovative design, it investigates methods for digital innovation in paper-cutting through four aspects: database construction and standardization, intelligent generation, immersive experiences, and personalized customization. It is argued that the transmission of paper-cutting from a new media perspective must shift from static preservation to dynamic dissemination. By using databases as a foundation, digital technology as a tool, and cultural significance as a baseline—and driven by the dual engines of dissemination strategies and innovative design—the sustainable transmission of paper-cutting art can be ensured.
