利用IDMH-Z780系统对碳素钢笔水书写字迹与印章印文交叉时序的无损检验研究

Determination of sequence of handwriting and seal impression by using IDMH-Z780 system

目的研究常见的碳素钢笔水书写笔迹与不同印章印文交叉时序的相关性。方法利用IDMH-Z780系统对制成的实验样本进行微观观察,并对三维数学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,书写笔迹色料分布发生数字图形曲面变化。结论用IDMH-Z780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。

Six hundred intersecting samples of handwriting and seal impression were analyzed with IDMH-Z780. The results showed that crossed marks are intact with no obvious change when the pen ink was written first,and the pen ink distributions will change when seal was stamped first.
