This study aims to propose a novel approach to address the high costs and complex processes of traditional glasses-free three-dimensional (3D) furniture decoration. It uses ultraviolet inkjet printing technology to achieve a glasses-free 3D decorative effect on furniture surfaces.
By leveraging the microlens array principle, transparent UV ink was printed onto a transparent substrate to simulate a micro-lens matrix. In contrast, a micrographic array was printed on a secondary substrate (or the reverse side of the transparent substrate). Their superposition generates autostereoscopic depth perception via the Moiré effect. Experimental validation compared two matrix arrangements: square-arranged (with circular or square textures) and hexagonal-arranged (with hexagonal or circular textures). Each was paired with micro-text arrays in an “A” pattern. Four furniture surface design concepts were ultimately implemented, incorporating floral motifs, traditional Chinese elements, Memphis-style patterns and gradient designs.
Results demonstrate that: Square-arranged matrices achieve optimal Moiré magnification at angles of 2–6°, with theoretical and experimental Moiré pattern period (M) deviations < 5 mm; Hexagonal textures outperform circular ones in image clarity and magnification efficacy; Square-textured matrices yield superior magnification quality versus circular equivalents. The printed furniture samples exhibited vibrant colors, distinct textures and dynamic 3D effects observable from multiple angles.
This study confirms the feasibility of using UV inkjet printing to create textured matrices, integrating glasses-free 3D effects into furniture panels. This approach enables cost-effective, glasses-free 3D furniture decoration, thereby expanding possibilities for personalized surface aesthetic design.
