基于栅格特征的打印软件环境研究
Research on Printing Software Environments Based on Grid Features
摘要
Abstract
This article has analyzed the relevance between grid features and various printing software environments and assessed relevant information of operating systems,print-driver programs,and word processing software in order to explore a new idea for identification of printer models.500 samples from 100 frequently used Chinese characters were made by Lenovo LJ2200,HP M126a,Panasonic KX MB1538CN,Brother MFC-7880DN,Brother HL-5585D,Lenovo M3410,Kyocera FS-1040,Lenovo LJ6700DN,Canon ip7280,FX CM118,Canon 2520i,HP M1136,Samsung CLP680,TOEC OEP4010DN printers with different resolutions(or quality modes)in Simsun font with 5pt,5.5pt,7.5pt,9pt,10.5pt,12pt,14pt,15pt,16pt and 18pt,and their relevant GSBS(Grid Simulation Bitmap Samples)were made.Comparisons were made between GSBS from same printers,same operating system(Windows),same type of word processing software but different print-driver programs to analyze the relevance between Grid Features and various print-driver programs.Comparisons were made between GSBS from the same printer,same operating system(Windows),same type of print-driver program but different types of word processing software(Word/WPS)to analyze the relationship between Grid Features and word processing software.Comparisons were made between GSBS from the same operating system(Windows),same word processing software,same type print-driver programs(PS)but different versions to analyze the differences of Grid Features between different printer models.Comparisons were made between GSBS from the same printer(TOEC OEP4010DN),same word processing software(WPS)but different operating systems(Windows/Linux Kylin)to analyze the differences of Grid Features between different operating systems.Factors such as the uniformity between the character outlines and the grid fit,hinting rules for pixel dropout,the size of character outlines mapped to device space and the type of curve describing the font can change the Grid Features.TFHS(Thickness Feature of Horizontal Strokes)has a significant relationship with the grid-fitting of character outlines;WFVS(Width Feature of the Vertical Strokes)has a significant relationship with the lateral size of the outlines mapped to the device space;LFOS(Ladder Feature of Oblique Strokes)is strongly related to the hinting rules for pixels dropout and the type of curve describing the font;DFPS(Distance Feature between Parallel Strokes)has a significant relationship with the vertical size of the character outlines mapped to the device space.Information of printing software environments(such as the type of operating system,type of print-driver program,hinting rule,and type of word processing software)can be analyzed by the Grid Features.This research has provided a new idea for the identification of some specific printer models by printed documents.关键词
