RGB [Black] Swatch to CMYK
INDD has RGB [Black] swatch.
How do I change it to CMYK [Black]?
The INDD was created with the intent of being digital only, but a year later, needs to be a print file.
[Black] is used both as text and as the background for white text.
Tried, unsuccessfully: "Edit/Transparency Blend Space", this no longer changes the [Black] swatch (this worked for 15 years, stopped working a few years ago).
Tried, unsuccessfully: "File/Document Setup", "Intent" from "Digital" to "Print", this has not changed the [Black] swatch from RGB to CMYK.
I have a workaround of creating a new CMYK Black swatch, but I'd prefer an actual solution.
Ideally, I'd prefer a solution that doesn't envovle having to make setting adjustments everytime I export to PDF.
I have read solutions in these discussions, but none of them have helped.
InDesign 2024 19.0, Windows 10.
Thank you in advance.
