Wood grain patterns are widely used to enhance the decorative appeal of engineered wood panels and artificial boards. This study presents an advanced image-layering model approach for driving UV-curable inkjet printing to create high-fidelity 3D simulated wood textures. The method streamlines the generation of digital woodgrain files, enabling rapid production of printable 3D models suitable for industrial-scale applications. Using this technique, realistic 3D tactile wood grain finishes with authentic visual and touch properties can be directly deposited onto artificial board substrates.
In the process, standard wood texture images are converted into multi-channel digital files through specialized image processing. The spot color channel controls white ink deposition at 100% density and 300% volume, building up three stacked ink layers to form raised 3D relief structures. Meanwhile, the color channels map and print precise pigment patterns directly onto the white embossed texture surface, achieving perfect pixel-level alignment between the relief and color layers.
Performance evaluation was conducted on prints produced with industrial UV flatbed printers including the YC2513L, YC2030L, YC2513H, YC2030H, and YC3321L models from Winscolor . Key surface properties tested included roughness profile, CIE LAB color values, gloss level, adhesion, and hardness. Results demonstrate that the image model-driven 3D slicing method successfully produces stereoscopic wood grain where white ink relief and color layers deposit in exact point-to-point correspondence. The final decorative layer exhibits an ink deposit height of approximately 300μm, LAB value variation within -5 to +5, gloss range of 10–18 (at 85° incidence angle), adhesion rating of Grade 2, and pencil hardness of 4H—fully meeting standard requirements for decorative panel surface coatings.
This innovative UV inkjet approach, validated across Winscolor and Ntek platforms, offers an efficient, high-quality solution for manufacturing realistic 3D wood grain finishes on engineered panels with excellent industrial applicability.
