需要帮助/答案PDF颜色分离 [英] Need help/answers on PDF color seperation
问题描述
使用以下过程：
- 当用户打印虚拟打印机时，PDFCreator创建了一个PDF
- 使用集成的VBScript处理程序进一步处理PDF，并传递到使用PDF内容进行一些处理的JAVA
- 在过程中间，外部应用程序
- 收集PDF，每周一次交付给每个CMYK使用印版的印刷店
- A PDF is been created by PDFCreator, when a user prints something to the virtual printer
- The PDF gets further processed with integrated VBScript handler and passed over to JAVA which does some processing with the PDF content
- In the middle of the process an external application is called with the PDF that adds black text and graphics to the PDF
- The PDFs are collected and once a week handed over to a print shop that uses a plate for each CMYK
问题是：打印店需要一个颜色分隔的CMYK PDF，但是添加的黑色文本&来自外部应用的图形应该是K平面上的唯一内容（因为我们想要产生特殊的打印效果）。所有其他通过PDFCreator打印的内容应该只在CMY板上，所以黑色必须模仿这些颜色。
The problem is: the print shop needs a color seperated CMYK PDF, but the added black text & graphics from the external app should be the only content on the K plane (because we want to make a special print effect). All other content which has been printed via PDFCreator should be on CMY plates only, so black must be emulated with those colors.
目前，我们手动制动过程调用外部应用程序和通过Adobe Creator Pro分离颜色，但这是没有未来的选择，因为整个过程应该自动工作。
At the moment we are manually braking the process before calling the external application and seperate the colors via Adobe Creator Pro, but that is no future option because the whole process should work automated.
所以基本上，我需要一种方式来转换CMYK PDFCreator PDF到CMY版本只有这样外部应用程序可以投入尽可能多的黑色K内容，根据需要。
So basicly I need a way to convert the CMYK PDFCreator PDF to a CMY version only so the external app can throw in as many black K content as needed.
PDF转换是正确的方向至？有没有办法w / ghostscript怎么办呢？我读了gs文档，但没有地方，因为我只看到RGB到CMYK转换，但没有CMYK到CMY与空B ...
Is the PDF conversion the right direction I'm heading to? Is there any way w/ ghostscript how this can be done? I read the gs documentation but got nowhere as I only saw RGB to CMYK conversion but no CMYK to CMY with empty B...
推荐答案
p>我相信PDFCreator只是ghostscript的一个包装，所以你可能有一些喜悦在 ghostscript邮件列表。看来gs支持一些刚刚发布CMY的打印机这个功能很可能在那里。
I believe that PDFCreator is simply a wrapper around ghostscript, so you may have some joy on the ghostscript mailing lists. It seems that gs does support some printers that just ouput CMY so this functionality is likely to be available in there.
你不会更好的使用一个新的分离称为黑色？印刷店不能处理这种情况吗？
Wouldn't you be better off using a new separation called Black? Can't the print shop handle that?
