需要有关 PDF 分色的帮助/答案
使用以下过程:
- 当用户将某些内容打印到虚拟打印机时,PDFCreator 创建 PDF。
- PDF 使用集成的 VBScript 处理程序进行进一步处理,并传递给 JAVA,JAVA 对 PDF 内容进行一些处理
- 。使用 PDF 调用外部应用程序,将黑色文本和图形添加到 PDF 中
- 收集 PDF 并每周一次交给印刷店,该印刷店为每个 CMYK 使用一个印版
问题是:印刷店需要一个颜色分离的 CMYK PDF,但添加了黑色文本& 来自外部应用程序的图形应该是K平面上的唯一内容(因为我们想要制作特殊的打印效果)。 通过 PDFCreator 打印的所有其他内容应仅在 CMY 印版上,因此必须用这些颜色模拟黑色。
目前,我们在调用外部应用程序之前手动制动该过程,并通过 Adobe Creator Pro 分离颜色,但这不是未来的选择,因为整个过程应该自动化运行。
所以基本上我需要一种方法将 CMYK PDFCreator PDF 转换为 CMY 版本,以便外部应用程序可以根据需要添加尽可能多的黑色 K 内容。
PDF 转换是我前进的正确方向吗? 有没有什么办法可以用ghostscript来做到这一点? 我阅读了 gs 文档,但一无所获,因为我只看到 RGB 到 CMYK 的转换,但没有看到 CMYK 到 CMY 的空 B...
Using the following process:
- 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
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.
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.
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.
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...

我相信 PDFCreator 只是 Ghostscript 的包装,因此您可能会对 ghostscript 邮件列表< /a>. 看来gs确实支持一些打印机,它们只输出CMY,所以该功能可能在那里可用。
使用称为黑色的新分离不是更好吗? 印刷厂不能处理吗?
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.
Wouldn't you be better off using a new separation called Black? Can't the print shop handle that?
