Normally we print vinyl banners for outdoor use. There are a lot of great things you can use a banner for when you are inside, however, and you shouldn’t limit yourself to using banners outdoors!
In this case, our customer used banners indoors to label the aisles in a library. They used our aluminum hanger bars to dress them up and as a way to hang them.
We always recommend using the matte finish vinyl for indoors. Glossy vinyl will give you reflection trouble in indoor lighting.
