判断纸张折痕与写印字迹先后次序的实验研究

An Experimental Research on Judging the Order of Folding Marks and Written-and-Printed Writing

添改文件属于变造文件的一种,在污损文件检验中占据重要地位。对一份疑似添改的文件进行真伪识别,不仅要看形成文件的物质材料的理化性质是否遵循其正常的变化规律,还要看整份文件的形成过程是否符合正常的行文程序。由于各种色料与纸张折痕交叉,不同形成次序时交叉部位呈现出来的表观特征存在差别,因而能够根据这种差别判断色料与折痕形成的先后次序,进而为确定一份可疑的文件是否存在添改事实提供依据。

A document with added words is one of the fabricated documents and occupies an important position in examining the defiled and damaged documents. When examining a document suspected to be a fabricated one, we should not only see whether the textural qualities of its formative materials tally with their natural changing orderliness but also observe whether the formative process of the whole document accord with its proper writing procedure. Since there are different characteristics caused by the different paper materials and paper＇s folded marks in different forming orders, we are able to distinguish the orders of paper＇s colors and fouled marks accordingly so as to provide references to make sure whether it is a document with added facts.
