摘　　要：研究了几种涂布喷墨打印纸的性能,利用扫描电镜SEM分析涂层的孔隙结构,包括孔径、孔径分布、颜料颗粒的大小和形状,及其他表面特性。在此基础上,打印由线条和圆点组成的图像,通过图像分析仪分析了打印墨点和线条的质量,结果表明,表面涂层的质量对图像清晰度影响很大,尤其是孔的形状及孔径分布影响更大。Surface properties of several ink-jet papers were measured, and coating layer structure （ including pore size, pore size distribution, pigment particle size and shape, etc. ） was analyzed by using Scanning Electron Microscope （SEM）. A testing image composed of a series of hnes and dots was printed on four ink-jet papers by Epson printer. The printing dots and lines quality, which could reflect the sharpness of image was measured by Image Analyzer. Dot quality （diameter and circularity） is influenced by paper coating structure, ink absorption and contact angle. With increasing the printing resolution, the line quality （width and edge roughness） is less influenced by paper properties.
