(Taken from Wikipedia) ** A decal (pronounced /ˈdiːkæl, ˈdiːkəl/) or transfer is a plastic, cloth paper or ceramic substrate that has printed on it a pattern that can be moved to another surface upon contact, usually with the aid of heat or water. The word is short for "decalcomania." The word Decalcomania is derived from the French word "decalquer," and was coined by Simon François Ravenet about 1750. The "mania" was added during the Decal craze of the late 1800s.
Different variations of decals include: "water-slide" or "water-dip"; and vinyl "peel-and-stick". A water-slide (or water-dip) decal is a type of decal that must first be dipped in water prior to its application. Upon contact with water, the glue is loosened and the decal can be removed from its backing. A vinyl "peel-and-stick" decal is a petroleum based decal that transfers upon peeling off the decal from its base.
