I am trying to convert an InDesign document to a pdf for use on a commercial printing press, but every time I export it changes all my K100 text to what Acrobat is reading as RGB. I've done this many times before and never had a problem, and I've checked all my colour setting and export options, but I just can't seem to figure out what is causing this. I've even tried taking the document to another computer and exporting from there. I got the same results though, so I think it must be a problem with the document, but the text is definitely set to K100. All objects which are supposed to be K100 are exporting just fine. It is only the text that is creating this problem. Any help you could offer would be greatly appreciated.
I've tried Press Quality, High Quality Print, and Adobe PDF Preset 1. I've even tried to define my own export settings, but I honestly can't remember all the things I tried. All of them created the same problem. Under Appearance of Black I have Display All Blacks Accurately, Output All Blacks Accurately.
I've tried No Colour Conversion, Convert to Destination, and Convert to Destination (Preserve Numbers). And the destination profile is the same as the document profile (U.S. Web Coated (SWOP) v2). I am using Adobe Acrobat 8 Pro.
I also forgot to mention that I tried converting the text to outlines, and that fixed the colour problem, but it got rid of all my underlines. But even if I could figure out how to convert to outlines without loosing information it doesn't seem like I should have to do that, especially since I've done this many times before with no problem. The document is the newest edition of a newsletter that we've printed many times, and it uses all the same setup as the old ones.
When I look at the sample PDF you sent and set the Acrobat output preview to SWOP v2, the type is all 100K. Are you sure the simulation profile is set correctly in Acrobat on your end? It's at the top of the output preview window.
I'm positive that the simulation profile is correct, but since you said that I just went ahead and took the image to my RIP, and the separations show up correctly there, so I guess problem solved in that respect, but I would still really like to know why it's showing up wrong in Acrobat, especially if this is something it is going to do again.
Thank you for your help. I guess the problem wasn't really a problem after all.

Try using a PDF/X preset. With PDF/X an output intent profile is included and Acrobat defaults to that as the simulation profile. I don't think you could have the problem you are describing with a PDF/X-1a or X-4 export unless you set the output destination to something other than Document CMYK.
