A Comparative Study on Version Characteristics and Temporal Attributes of Songti Font
摘要
Abstract
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.关键词
