Does anyone have an idea about how the news sheet worked on the show Babylon 5?

That’s if you’ve seen or remember the show. I recall a scene where one of the characters went to a wall-mounted terminal, keyed or swiped something and got a ‘flimsy’ with the daily news from Earth printed on it, in an ‘old-style’ for the show newspaper format of columns. The flimsy is what puzzled me at the time and today.

I couldn’t figure out how it could be read without a background, only the words and pictures were printed, so the rest of the sheet was clear. How would that work?
