为克服分色版EPS文件导致的印前流程系统应用不畅、地图出版效率不高的缺陷,提出了一种分色版EPS文件的自动合成方法。该方法基于测绘生产部门现有的分色版文件,通过专色还原、分版叠加和压盖关系修改3个环节,自动生成合版EPS文件。实验证明,该方法生成的合版EPS地图要素齐备、颜色准确、压盖关系正确,可方便地进入印前流程系统实现数码打样和激光发排。
To overcome shortcomings of separate EPS files including slack connection to prepress flowing system and inefficient map publish, an automatic combination method was presented. It consisted of 3 key steps. Firstly, the colorful state of each separate EPS file was come back. Secondly, all elements in various separate EPS files were combined into a composite EPS file. Finally, the graphics state of composite EPS file was modi- fied as overprint. The experiment showed the composite EPS file can satisfy both digital proof and RIP.
