Foam core is by far the cheapest material for sign printing. It is made with foam sandwiched between two matte paper layers. Foam boards are rigid and lightweight which is great for temporary signage or pop-up displays.
The matte paper coating helps with printing applications, especially with photography, but unfortunately disintegrates easily on outdoor signs from being in the elements. Foam core boards are best for interior purposes.
Signs can be single or double-sided depending on the use. While they are typically rectangular and either 12” x 18” or 18” x 24’, we can work with whatever dimensions you imagine!
