摘　　要：目的调频网点的微观立体形态质量会对数码印刷品质量产生根本影响,选择有效工具对调频网点立体形态进行准确还原。方法借助明暗恢复算法(SFS)对不同数码样张的网点立体形态进行恢复,并基于此分析打样纸张纸面状况对于油墨吸收的影响。利用扫描电镜技术采集纸张纵向与平面信息,将其扫描结果与网点立体数据进行分析对比。结果网点立体模型准确而直观地还原了单个调频网点及不同样张实地处的网点立体形态,并且实地处网点质量与电镜分析的结果相互一致。结论网点立体模型能真实地反映出喷墨过程中的网点传递特征,电镜分析技术为科学评价样张质量提供了进一步的科学理论支持。调频网点微观形态特性分析为更好地研究网点微观结构与数码印刷品复制质量的相互关系提供了有效手段。The 3D micro morphology of the AM dot has fundamental impact on the quality of digital proof. It is significant to choose effective tool to restore the FM dot accurately. On the basis of restoring dots in the digital proof by SFS algorithm, we analyzed the influence of the paper condition on the ink absorption and collected the surface and vertical information of the digital proofs through scanning electronic microscope（SEM） for comparatively analyze the restoring result and the scans. The 3D model of the single FM dot and solid area in different proofs were restored accurately and intuitively. The analysis results from the different solid areas were consistent with those from SEM. In conclusion, dot models could truly reflect the dot characteristics in detail during the process of ink-jet printing. The SEM technology provided further scientific support for evaluating digital proof quality. The analysis of micro characteristics of FM dot has become an effective tool to better study the relations between micro characteristics and digital printing proofs.
