| 摘 要： | 目的研究常见的打印字迹与不同印章印文交叉时序的相关性,为检验提供依据。方法应用DVI-300微痕迹色差分析系统对制成的实验样本进行实体观察,并对微痕迹色差模型图进行特征分析。结果先墨后朱,交叉部位字迹边缘状态完整,等高线宽度、流向未见明显变化;先朱后墨,交叉部位中心字迹等高线排列出现游离状态,色料分布发生数字图形曲面变化。结论用本系统可以观察、分析朱墨交叉部位的微观特征和无损检验研究。

| Abstract: | Hundreds of crossing texts samples of laser printing and stamp impression were made by four kinds laser printer,and then the crossing lines were analyzed by using DVI-300 analysis system.The results showed that 3-D topography gave conclusive information about the writing order and the DVI-300 analysis system will be a promising technique. |
