What is Foam Core Mounting, and How is it Done?

In our last article, we spoke about oversize printing for trade shows and conventions.

If you’ve ever been to a trade show, convention or any event with a lot of signage, you’ve probably come across a foam core mounted sign of some kind.

Foam core is lightweight, and easily cut material used for the mounting of photographic prints. It is made up of three layers. The inner layer is made of polystyrene foam clad, with the two outer layers made of white claycoated paper.

The board is then used as a backing for large color posters and banners so that they are sturdier and can stand up straight.

It is usually self adhesive, so special techniques (that vary depending on size) are needed to mount the printed poster onto the board so that it looks flush and free of bubbles or any other imperfections.

The video below shows a large poster being mounted onto a piece of foam core.

After the print is mounted onto the foam core board, the board then needs to be trimmed so the artwork is flush to the edge of the board, and so that the edges are even on all sides. We use a KeenCut Excalibur A-Frame Vertical Cutter to cut our foam core here at Replica Printing Services. Below is a video of a piece of foam core board being cut on the Vertical Cutter.

Once the foam core sign is printed, mounted and cut, it can then be placed on a small stand so that it can stand up straight at a trade show booth. Below is an example of a map that was printed and mounted onto foam core.

So next time you are at a trade show or convention and you see a large floor standing promotional sign,  you will have an idea of how that sign was printed and mounted!

  1. I have been browsing online more than 3 hours today, yet I never found any interesting article like yours. It’s pretty worth enough for me. In my view, if all webmasters and bloggers made good content as you did, the internet will be much more useful than ever before.

    1. Hi Carron, sorry for the delayed response. Unfortunately, there is not much you can do to reverse warped foam core. However, in the future to prevent this from happening again, you can try mounting paper of similar weight on the opposite side. The foam core warps due to the expansion and contraction of the paper mounted onto it and by counter-mounting something on the back you can cancel this out. We hope this helps and thanks for taking the time to comment!
