We don't print wallpaper usually but got a chance to do so with Fia Backström for her show a the Whitney Biannual.
Here's how we set up it for a stationary screen. Usually wallpaper is printed on long table and the screen is moved along the paper. We couldn't really do that, but this worked pretty well.
We set up a few tables and inverted some of our drying fans.
The paper was fed off of a roll. We had already printed the blue background.
We used two reg tabs along the bottom to keep everything running straight.
We marked the paper at two points that lined up with our reg.
