研究不同印油的印章印文与静电复印字迹交叉部位的笔画洇散程度,根据笔画增宽度的不同来判断复印文件的朱墨时序。通过制作先朱后墨和先墨后朱的两种时序的复印文件实验样本,在文检仪、读数显微镜下观察交叉部位的笔画洇散,记录相同时间段内的不同印文色料在不同朱墨时序下的笔画增宽度。研究实验表明:在不同朱墨时序下的交叉笔画部位色料都会出现笔画增宽的现象;油性印文色料在先墨后朱时序比先朱后墨时序的笔画增宽度大。
To study the degree of strokes in different parts of the stamp seal and xerographic copy of different ink stamps, and to judge the timing of the ink copy of the photocopied document according to the increase of stroke width. Through making the experimental samples of photocopying documents of the two kinds of sequence after the first ink and the second ink, we can observe the strokes scattered at the cross place under the inspection instrument and the reading microscope, and record the difference between different imprinting materials in the same time period The increase of strokes under the sequence of Zhu Mo. The experimental results show that the strokes of the cross-strokes in the different ink-ink timings will all have the phenomenon of strokes widening.
