高精度彩色出版技术的研究

Research on High Precision Colorful Publishing Technology

《天翼结构化彩色号簿出版系统》实现了保存在大型数据库中的数据信息的自动排版输出。文章以该系统为出发点,对高精度彩色出版的关键技术之一——EPS彩色页面输出技术进行了研究,介绍了PostScript语言的基本特性,并重点讨论了输出页面的PostScript描述、文字输出和字体管理、坐标系统变换、图形文件嵌入等几个方面的内容。最后对这一技术的应用前景做了展望。

In this paper, we discuss the EPS technology that is one of the key technology of high precision puplishing base on 'Tianyi Structured Colorful Telephone Directory Publishing System', in which the problem of converting date stored in RDBMS to high precision publication automatically was implemented. At first, we outline the basic characteristic of PostScript language, then, discuss page description using PostScript language, ' words outputting and font managing,coordinate system transformation and importing in detail. Finally, the future application of this technology is given.
