Thank you for checking. Looks like a bug in Acrobat (older version 11.0.23), not ConTeXt. What editors do you use? After your test I was digging deeper. When I disable black plate in *Preview: Separations* it doesn't show an overprint, the room under the letters is white (original problem). When I remove one overprint manually in Illustrator, Acrobat shows the remaining overprints. I've found out later, I could use *Profile: Color Warnings*, where all overprints are visible, but I would rather see it in separated plates. Hope this helps someone in the future, too.

Hello, may I ask someone, who understands knockout and overprint in the printing press, to check test cases in the attached file from the test suite, if overprint is working or not in Mark IV, please?
