How do I convert rich black text to 100%K?

[elizabeth7166]

I am preparing ads for a print publication. I am trying to change small rich black text to 100% K. I use the editing tools and set the sliders to 100% K but it just changes the text to RGB after I close out of the editing tools. Is there some way to "apply" change? What am I missing?

This question is about a PFD in Acrobat CD.

Oops. PDF, of course.

Acrobat Pro DC. Think I am dyslexic today.

The Edit tools convert CMYK to RGB, so don't go anywhere near them!

So I cannot convert embedded text to 100%K in the PDF? I have to open in Illustrator and hope I have the font?

Illustrator is not a general PDF editor: not recommended at all.

I don't know if you can do this in Acrobat, but what I'm saying is don't go near the Edit tool. Look elsewhere.

In Acrobat Pro the simplest is to use  Convert Colours under Prepress tools. You can choose to convert text objects only and Keep Black and Promote CMYK-K to Balck. Also converting to a greyscale profile will also convert to black. There is of course the above mentioned preflight, and you can also make a preflight into a droplet so that you can apply the fix by just dropping files on it.

Greetings Lukas:
I'm told by my book publisher that my PFD contains 4 color black type. I've used "Convert Colors" option with the "Photoshop 5 default CMYK" selection for any object and color space. I've also opened the "Ink Manager" and checked the "Convert all Spots to Process" option. Then I chose the "Preserve Black" option. Wouldn't this ensure that all the text is rendered on the black process plate? In other words, rendered in black with no separation. I'm stuck and would really appreciate any advice on how to keep all the text in my book black.
Thank you in advance,

Preflight -> "Correct 4C Black" works fine.
