The combination of these features makes screen printing the process of choice for many diverse end uses. In the industrial setting, screen-printed labels and decals are used because they can withstand harsh environmental conditions such as heat, cold, prolonged exposure to sunlight, exposure to industrial solvents, etc. In the area of prime product labeling, the opacity of UV screen printing enables manufacturers to achieve very high quality graphics on labels that give the "no label" look on clear containers. The presence of color adds to the label's shelf appeal and is often elected by marketing departments for this advantage. These qualities are especially important for cosmetic products, hair care products, etc.
