Reflective decals and signage

Decal is composed of the following layers from top to bottom:

1. 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.
2. An adhesive layer is applied to the bottom of the face stock.
3. A silicone or release coating layer is applied to the upper side of the backing material.
4. A paper or film liner provides the bottom layer of the labelstock.

Different variations of decals include: water-slide or water-dip; and vinyl peel-and-stick. A water-slide (or water-dip) decal is screen-printed on 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; overly long exposure, however, dissolves the glue completely causing the decal to fail to adhere. A peel-and-stick decal is actually not a decal as described above, but a vinyl sticker with adhesive backing, that can be transferred by peeling off its base. The sign industry calls these peel-and-stickvinyl stickers vinyl-cut-decals.
