Convert all to CMYK

Aaak. I have spent hours trying to make sense of all the permeatations of  Ghostscript documentation in an attempt to do one simple thing. Having used PDFcreator for other tasks, I am familiar with the software, but was unaware it could actually transcode the RGB images while simultaneously working with the text. But after spending hours of trial and error, I am having problems still.

The project: Take an OpenOffice writer document that includes color text, black text and RGB images and convert it to a 100% CMYK PDF

The Problem: I set the standard PDFcreator options to use CMYK (prepress, embed all fonts, Use Color Model CMYK, and crank out a PDF, and the rendered document includes RGB images (according to PDF/x-3 Inspector for Adobe Acrobat) . I then add the standard Ghostscript parameters "-dTextAlphaBits=4|-dGraphicsAlphaBits=4|-dDOINTERPOLATE" and the PDF does not generate more than 1 page of the document. The problem appears to be with the -dGraphicsAlphaBits=4 setting.

Question: How can I generate a 100% CMYK document with true black for the black text using PDFcreator? Are there better Ghostscript settings (e.g. use any of the -dConvertCMYKImagesToRGB=false | -sProcessColorModel=DeviceCMYK | -dProcessColorModel=/DeviceCMYK | -sColorConversionStrategy=CMYK settings)?

 

Thanks you for any help. I am going bald on something that seems like it should be easy.

Sorry about the double post. The original post did not show up for awhile and was waiting moderator approval.

Does anyone have any ideas about what could be going wrong, why I am only getting a single page spit out, an why the CMYK settings are not working?
