宋体字库版本特征和时间属性的调查比较研究OA
A Comparative Study on Version Characteristics and Temporal Attributes of Songti Font
在文件检验实践中,对于添改文件的关注点多在于不同印制特征、不同字体等方面,鲜有人注意字体不同版本带来的差异.本文收集了 16种不同版本的宋体字库文件,基于中文常用3 500字范围对字库版本差异进行比较研究.首先,通过Python对字库文件进行图像渲染和差分比对,从数字化层面提供了新的研究路径;其次,选取对应汉字字符利用文检仪VSC8000进行打印文件重合比对,验证差分比对的可行性.在渲染图像和打印文件比较中,发现版本5和早期字库版本之间存在较大差异,结合版本之间不同的发行时间,可以此发现文件内潜在的时间属性问题,为侦查破案提供新思路和新方法.
In forensic document examination,investigations of altered documents typically focus on variations in printing characteristics and font types,with limited attention to discrepancies arising from different versions of the same font.In this study,16 distinct versions of Songti typeface files were collected and conducted a comparative analysis of their typographic differences within the framework of 3 500 commonly used Chinese characters.The methodology comprised two phases:(1)Digital characterization through Python-based image rendering and differential comparison of font files,establishing a computational approach for version discrimination;(2)Validation using the VSC8000 document inspection system to perform superimposition analysis on printed specimens containing selected characters.Comparative analysis revealed significant typographic variations between Version 5 and earlier Songti releases.When cross-referenced with version release timelines,these discrepancies enable the detection of temporal attributes of the documents,thereby offering innovative methodologies for criminal investigations.
