摘　　要：油漆笔作为一种新型记号笔,具有耐水、耐光、不易褪色等特点,适合在多种材料上书写、绘画和标记,较多应用于施工作业中。近来,检验人员发现有违法犯罪嫌疑人利用油漆笔来书写标语、恐吓信等,且书写位置常位于无监控覆盖的视野盲区,给侦查人员带来了较大的技术挑战,造成了极其恶劣的社会影响,影响了风清气正的政治生态环境,但实务界缺乏油漆笔的相关研究。基于此现状,通过模拟实际案件情况开展实验,采集25名书写者用站姿、持油漆笔在光滑客体上书写的字迹,同正常书写的字迹进行比较检验。通过特征比对、统计分析,总结出油漆笔书写字迹的笔迹特征及其变化规律,正确认识和分析油漆笔书写笔迹特点,丰富检验理论框架,寻找字迹里的“DNA”,有利于此类案件中快速筛查、重点排查,为相关笔迹鉴定提供一定的识别和评断的参考依据。Paint pen as a new type of marker pen,with water resistance,light resistance,not easy to fade and other characteristics,suitable for writing,painting and marking on a variety of materials,more used in construction operations.Recently,inspectors have found that criminal suspects use paint pens to write slogans,threatening letters,etc.,and the writing position is often located in the blind field of vision without monitoring coverage,which has brought greater technical challenges to investigators,caused extremely bad social impact,and affected the political ecological environment of clean air,but the practical community lacks relevant research on paint pens.Based on this situation,an experiment was carried out to simulate the actual case situation,and the handwriting of 25 writers on smooth objects with standing posture and paint pen was collected and compared with the normal handwriting.Through feature comparison and statistical analysis,the handwriting characteristics and change rules of paint pen handwriting are summarized,the characteristics of paint pen handwriting are correctly understood and analyzed,the theoretical framework of examination is enriched,and the"DNA"in the handwriting is found,which is conducive to the rapid screening and key investigation in such cases,and provides a certain reference basis for the identification and evaluation of related handwriting.
