No background showing in pdf

[Suzy251276073ems]

Somehow the dark background of my presentations turn to white when I convert them to PDF. Even older PDF's with a dark background at the time now all have a white background. Because I use white fonts for titles, this is not userfriendly at all for my students.

I thought I had found a solution: you should uncheck 'Replace document colors' in the accessibility options. Maybe it's because of the new interface of Adobe, but even by using the Help option I can't find this option. Can anybody please let me know what I can do to keep the dark background?

Thank you!

You will find this option under the Accessiblity category in Acrobat's preferences.

Thank you, Karl Heinz. That was the answer I found earlier, but somehow my interface is completely different. I have searched for preferences, I have searched for accessibility, but no such luck. What am I missing?

Found it! I was looking in the tools, but I had to go to the menu and select preferences there. Brain fog is a real thing, I'm afraid. ;^)

Glad you found it. Yes, the "Preferences" are in Acrobat's menu system - and unfortunately in different locations depending on Mac vs. Windows.
