摘　　要：目的研究以UV喷墨为成型材料的彩色3D打印方案。方法以纸张为承印介质,采用UV喷墨打印方式,在5张同种纸张表面打印不同墨层数的黄、品、青、黑和白等5种颜色的色块和IT8.7-3CMYK i1 PM 5.0.5标版,对比分析不同墨层数色块的厚度和颜色再现情况,以及白色油墨对色域的影响。结果对黄、品、青、黑、白等5种油墨来讲,第1层油墨会与纸张表面发生较强的渗透和铺展作用,影响高程精度;随着墨层数增加,黄、品和青等3种色油墨的亮度逐渐下降,色相逐渐偏离;在纸张表面均匀打印1层白色实地油墨,可改善纸张偏色情况,且白色油墨具有较好的色彩再现性。结论能够以多层白色油墨的叠加实现3D模型的高度,以若干层彩色油墨打印实现3D模型的色彩方案,从而实现UV喷墨彩色3D打印。The aim of this work was to study 3D color printing based on UV ink. When paper was used as the substrate, yellow, magenta, cyan, black and white patches with different ink layers and IT8.7-3 CMYK 5.0.5 standard version were printed on five pieces of paper with the same type using UV ink-jet printing. Then the thickness and color reproduction of different ink layers and the effect of white ink on color gamut were compared and analyzed. In terms of yellow, magenta, cyan, black and white ink, the stronger penetration and spreading effect of 1st ink layer on the paper surface influenced the precision of height. With increasing ink layers, the brightness of yellow, magenta and cyan ink gradually decreased, and the hue gradually deviated. Color shifting of paper could be improved after printing a uniform layer of white ink on the paper, and the color reproduction of white ink was better. In conclusion, to realize UV ink-jet 3D color printing, a scheme was proposed which achieved the height of 3D model with multilayer of white ink and the color of 3D model with several layers of color ink.
