Adecal(/diːkæl/,/dɪkæl/,/dɛkəl/,/deɪkæl/) ortransferis aplasticclothpaperor ceramicsubstratethat has printed on it apatternor image that can be moved to another surface uponcontact, usually with the aid ofheatorwater.

The word is short fordecalcomania, which is the English version of the French worddcalcomanie.

The technique was invented bySimon François Ravenet, an engraver from France who later moved to England and perfected the process he called dcalquer (which means to copy by tracing); it became widespread during the decal craze of the late 19th century.

A decal is composed of the following layers from top to bottom:

A paper or film face-stock makes up the top layer of the labelstock. The printing is done on the upper side of the facestock.

An adhesive layer is applied to the bottom of the face stock.

A silicone or release coating layer is applied to the upper side of the backing material.

A paper or film liner provides the bottom layer of the labelstock.

An RFID circuit (chip and antenna) can be included in the paper or film face stock.

Different variations of decals include:water-slideorwater-dip; and vinylpeel-and-stick. A water-slide (or water-dip) decal isscreen-printedon a layer of water-soluble adhesive on a water-resistant paper, 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; overlong exposure, however, dissolves the glue completely causing the decal to fail to adhere. Apeel-and-stickdecal is actually not a decal as described above, but avinylsticker with adhesive backing, that can be transferred by peeling off its base. The sign industry calls thesepeel-and-stickvinylstickersvinyl-cut-decals.

Mass-production of vinyl decals starts with large rolls of vinyl sheet. Vinyl is fed through a plotter or large-format printer/cutter which prints the desired image and cuts out the desired shapes. Designs are typically created using specialized computer software and sent to the machines electronically. After the patterns are cut, excess vinyl on the sheet is removed in a process calledweeding.[1]Finally, a paper pre-mask can be applied to the top of the vinyl design allowing easy application of multiple letters and shapes.

Decals are commonly used onhot rodautomobiles andplastic models. They are also used onguitarsas a way of personalizing them.

Government agencies (and some Private Public Partnerships) use decals on vehicles for identification.[2]These decals are referred to as fleet markings and are required by law on all fire and law enforcement vehicles in the US. Most fleet markings are created from reflective vinyl with an adhesive backing that is applied in a peel-and-stick manner.
