A decal (/ˈdiːkæl/, US also /dɪˈkæl/, CAN /ˈdɛkəl/)[1] or transfer is a plastic, cloth, paper, or ceramic substrate that has printed on it a pattern or image that can be moved to another surface upon contact, usually with the aid of heat or water.
The technique was invented by Simon François Ravenet, an engraver from France who later moved to England and perfected the process he called "décalquer" (which means "to copy by tracing"); it became widespread during the decal craze or mania of the late 19th century.
As manufactured, which consists of the artwork printed on the upper side of a paper or film label stock, temporarily affixed by a typically water or heat soluble adhesive to the upper side of a silicone- or other release agent-coated paper or film backing stock.
Finally, a paper pre-mask[clarification needed] can be applied to the top of the vinyl design allowing easy application of multiple letters and shapes.[how?]
A recent innovation involves the inclusion of a radio frequency identification (RFID) circuit (chip and antenna) in the paper or film facestock.[why?
