两类可变数据印刷应用方案的实践

目的研究和比较常规印前处理软件和专业级软件这2种可变数据印刷应用方案,总结得出2种方案在可变数据印刷作业的设计方法和输出效率方面的差异。方法分别以Adobe Photo Shop,In Design和Altas Print Shop为工具,通过"图书借阅证"案例,对比普通印前处理软件和专业级可变数据印刷软件在可变数据印刷设计方面的功能特点。通过分析Print Shop软件导出的PPML格式的可变数据打印文件,研究可变数据印刷系统的工作原理。结论相比常规印前处理软件,专业级可变数据印刷软件不仅能够能完成可变数据作业的设计和制作,还能输出专用的可变数据文件格式,这些专用格式能够准确描述打印机光栅化处理器(RIP)可识别的页面静态信息和可变信息,使得静态内容和动态内容能够单独RIP,提高印前作业的处理效率。

Two Variable Data Printing Applications

It aims to study and compare such two Variable Data Printing (VDP) applications as traditional prepress treatment software and professional software so as to summarize the differences of the two in design approaches and output efficiency. With "Library Card" as an example, traditional prepress treatment software and professional VDP software were compared from the aspect of respective functions in VDP design by the tools of Adobe PhotoShop, InDesign and Altas PrintShop. A VDP job file in PPML format exported by PrintShop was analyzed in order to study the principle of VDP system. In conclusion, compared with the traditional prepress treatment software, the professional VDP software can not only design the VDP jobs but also output the job files in proprietary VDP format. These types of proprietary VDP formats can accurately describe the static content and variable content in print pages which can be identified by Raster Imaging Processor (RIP) of digital printers. The static content and variable content in print pages can be processed respectively by the digital printers'' RIP. And the processing efficiency will be improved.
