UV打印3D竹编纹理的性能及美学评价

Evaluation of Performance and Aesthetic for UV Printing 3D Bamboo Woven Texture

竹编作为中国传统艺术形式具有优异的装饰性、实用性和环保性,但在家居产品上的应用还是存在生产效率和经济效益上的局限性。提出一种基于数字分层图像处理的紫外光固化(UV)喷墨打印方法,通过数字竹编图像处理在杨木多层板表面构建了具有微立体结构的竹编肌理。研究表明在CMYK通道格式下的图像,通过色彩范围选择和模糊参数设置将图像转化为灰度图像,灰度图像链接专色通道控制白色油墨沉积,打印密度为300%并在基材表面多层沉积,高度模拟竹编藤编的凹凸质感;CMYK通道控制四色油墨精准映射进行彩色打印。基于上述方法,在杨木多层板上成功模拟出具有极高相似度的竹编表面装饰效果。漆膜物理性能测试表明油墨沉积粗糙度约为300μm,LAB差值为-5~5,附着力为2级,硬度为2H,耐磨度为3级,符合家具产品漆膜表面理化性能的国家标准。并引入层次分析法进行体系内各指标权重计算以及评价实践对该方法打印的表面纹理进行科学客观的美学评价。

As a traditional Chinese art form,bamboo and rattan weaving exhibits excellent decorative,practical,and environmental qualities.However,its application in household products is limited by production efficiency and economic benefits.A UV-curable inkjet printing method based on digital layered image processing was proposed in the study.Bamboo fabric with a micro-three-dimensional structure was constructed on the surface of a poplar multilayer board through digital bamboo image processing.The results show that the CMYK image is transformed into a grayscale image by color range selection and fuzzy parameter setting.The grayscale image was then linked to a spot color channel to control white ink deposition.The printing density was set to 300%,and multiple layers were deposited on the substrate surface.The CMYK channel accurately mapped the four-color inks for color printing.Using this method,a bamboo plaiting surface decoration effect with high similarity was successfully simulated on the poplar multi-layer board.Physical property testing of the paint film reveals an ink deposition roughness of approximately 300 microns,an LAB difference of−5 to 5,an adhesion of 2,a hardness of 2H,and a wear resistance of 3,all of which conform to national standards for the physical and chemical properties of furniture product surface coatings.Furthermore,the analytic hierarchy process was introduced to calculate the weight of each index in the system and to evaluate the aesthetic evaluation of the surface texture printed using this method.
