I just don’t understand it…
You can flip it if one side gets dirty or put it on a transparent wall.
For putting in the window of an establishment: visible from inside and outside.
Yeah…but on the other side it’s a mirror image. It’s illegible.
Probably because you have a movie poster that is meant to be put up in a cinema light box, printing on both sides means you get a much richer better quality image while a single sided print looks washed out.
