Hello, I have a document in CMYK. The 100K black text in some places is knocking out of the highlight colour and the header bar. Elsewhere in the document it has worked, but in some places not. How can I manually get this to stop knocking out and overprint?

There's a fixup in Acrobat's preflight panel to change overprint mode for Black text, as well as many other options

If you had Pitstop, this is much easier to do (or robust), as you can select individual objects to change their overprint mode.

Can you help by outlining the steps in Pitstop, which I have to fix overprint issues? Please and thanks

How did you make the document, and did you choose overprint there?

@Test Screen Name I didn't make it the document. It's a supplied PDF that I have to use. I had to flatten it to retain the highlights, and convert the text to 100K which I have done. Just these few spots where the text is knocking out.

The default is always knockout, so if some things overprint, then the supplier made it that way. However, it might be that flattening it breaks the overprint; overprint and transparency is a difficult mixture.

Here's another screenshot of the object inspector on that first line of text
