写字机摹仿书写笔迹检验探究

写字机实质是一种简易的数控装置,根据事先编排好的字库,转换为矢量图。该矢量图数据通过电子元件控制书写工具X、Y、Z轴移动路径从而在固定的纸张上留下接触的墨痕。目前写字机在淘宝上多有销售,不可避免地会被不法分子利用。从写字机摹仿书写笔迹的原理出发,结合对其摹本的比较,可探究写字机摹仿书写笔迹的特征,从而发现写字机摹仿书写笔迹与一般摹仿笔迹的区别。实验显示,检验涉嫌写字机摹仿书写笔迹的基本要点是:了解案情是否具有写字机摹仿书写的情形条件;分析检材笔迹笔痕宽窄、深浅是否均匀;与临摹、套摹笔迹存在本质差异;追根溯源寻求相关证据支持。

Inquiry on Writing Machine Imitating Handwriting Examination

The writing machine is a simple numerical control device in practice,which converts scanned or photographed handwriting on the paper into a vector diagram according to a pre-arranged font library. The vector diagram data controls the X,Y,and Z axis movement paths of the writing tool with electronic components to leave contact ink marks on a fixed paper. The writing machines are available on Taobao,and they will inevitably be used by criminals. From the principle of writing machine imitating handwriting,combined with the comparison of its copy,the characteristics are explored and the difference between writing machine imitating handwriting and general imitating handwriting can be found. Experiments have shown that basic points for testing suspected writing machine imitation writing include understanding whether the case has the possibilities of imitation,analyzing whether the width and depth of the handwriting is even,looking for essential differences with general imitating handwriting,and tracing the source to seek relevant evidence.
