Decal

A decal is a design printed or cut from an adhesive-backed material and intended to be transferred to another surface. They are used for decoration, labeling, or identification and are commonly made from vinyl, polyester, or paper. A decal typically consists of the design, an adhesive layer, and a release liner, sometimes with transfer tape to aid placement.

There are several types. Pressure-sensitive vinyl decals use a self-adhesive backing for easy application. Water-slide decals require soaking to release the design from a carrier film and then transfer to the surface. Some decals are permanent, others removable, and many are laminated for durability and UV protection.

Application generally begins with a clean, dry surface. For vinyl decals, the backing is peeled away, the decal positioned, and air pockets smoothed out with a squeegee or fingernail. Water-slide decals are dipped in water, slid onto the surface, then pressed flat and dried.

Removal and care depend on the adhesive and the surface. Most decals can be peeled off, though adhesive residue may remain. High-temperature or heavy weather exposure can reduce life expectancy. Properly laminated decals tend to last longer outdoors, while removable decals are designed to come off cleanly.

Common applications include automotive graphics, window and wall decor, product labeling, signage, laptop skins, model kits, and hobby crafts. In manufacturing, decals are produced by digital or screen printing, cut to shape, and optionally laminated for protection.
