摘要
为了研究经不同计算机软件处理和在不同打印模式下的电子文档在同一打印机打印输出后印刷特征的变化情况,探究不同计算机软件条件及打印模式对印刷特征的影响,本文制作了内容相同的电子文档样本,以常见的文档编辑软件、字库、驱动等计算机软件及常用打印模式作为文件打印的变量参数,观察分析所打印文件单字的形态结构、笔画粗细和搭配比例、笔画交叉点的位置关系、墨点形状、图像网点等形态特征。结果表明,一份电子文档在不同的计算机软件条件及打印模式下使用同台机具打印输出后,打印文件特征存在差异,且具有一定规律。这些特征规律可为确定文件物证的编辑方式和打印条件提供依据,为打印文件检验提供了新思路。
With the continuous progress of science and technology,the production of electronic printed documents has become very convenient.Using a series of applications software in electronic equipment such as computers to edit,and then directly printing through printers can realize the production of contract text.However,in the practice of forensic science,cases of criminals forging electronic documents and committing crimes happen from time to time,so it is particularly important to examine and identify electronic printed documents.In the process of making electronic printing documents,hardware equipment is the main factor that causes the difference in the characteristics of electronic printing documents.Meanwhile,the infl uence of software system cannot be ignored.To provide some reference for the inspection and appraisal work,this paper discussed the differences and similarities between the characteristics of electronic printing documents by studying some commonly used computer software such as document editing software,font library and print driver,as well as printing parameter(printing mode).In this paper,the commonly used text samples,formats and images in contract documents were collected,and common electronic contract samples were made.In the experiment,the printing hardware was kept unchanged,and only the variables such as software were studied.Then,the printed documents were observed through a microscope and a magnifying glass,and the software such as Photoshop was used for auxiliary detection,so as to analyze the morphological characteristics of word structure,the proportional relationship of word collocation,the position relationship of stroke intersection,the ink dots shape and image dots and other morphological characteristics,and summarized the printing feature law.These characteristics can provide a basis for determining the editing mode and printing conditions of document material evidence,and provide a new idea for printing document inspection.
