So what is the difference between a Decal and a Sticker?
Well decals are technically stickers but they are not the same thing. A decal is a sticker that is mainly for outdoor use, however they aren’t made as tough and will generally only last around three years if used outdoors (and if laminated).
They are a design that can be transferred from one surface to another and will have three layers: paper on the back, the decal itself (which is either Vinyl or Polyester), and paper on the front. They are most commonly made by using an eco-solvent printing process or latex inks with a Thermal color printer.
