Domed labels are printed pressure-sensitive labels that have a thick, dome-shaped clear polyurethane coating.
Domed labels are used in many applications. Equipment manufacturers apply them as permanent marking for their products as they are durable and their three-dimensional appearance catches the eye. Domed labels are much more permanent than many other labels and do not show wear; the clear polyurethane substance, even after curing (hardening), is self-healing. Minor scratches or cuts heal themselves and the label looks like new once again.
The polyurethane coating can be applied in liquid form in many different ways, ranging from manual application via syringe to optically-guided, automated dispensing equipment. Once applied, the polyurethane liquid flows to the edge of the label and stops (due to the surface tension of the liquid), hardening into a clear dome.
- The first layer is the label material. The material can be any print-industry recognised label material (from paper to many forms of plastic).
- The second layer is the ink. The label can be multiple colours, photo-quality graphics, or simple text. The ink is applied using screen or digital print technology.
- After the ink has cured (dried), the labels are laser- or die-cut and the waste material between labels removed from the press sheet.
- The liquid polyurethane material is then applied to the labels on the press sheet and left to cure to create the finished domed labels.
