How to check for 4-Color Black?

I routinely work files in InDesign(a lot of the artwork is linked), which to my knowledge does not have the ability to preflight 4-color black. I’ve not had any luck in Acrobat pro either. I save my files as PDFs. I have a PDF that I KNOW has 4 color black but when I run “List rich black objects”…I’m not getting any errors. Ideally, I’d like to be able to run a check in InDesign.


I Generally just use the Output Preview (Separations Preview) In Acrobat Pro

Untick the Black plate and if you still see something that’s supposed to be straight black it’s wrong and needs correcting.

You can do the same thing in Illustrator…..

Or in InDesign ……

This way you can check as you work if there’s a concern.

Acrobat Pro : View > Tools > Print Production > Output Preview

Illustrator : Window > Separations Preview
(Be certain to turn OFF the preview in Illustrator before saving anything for web… it messes with the web output)

InDesign : Window > Output > Separations Preview
