Button copy
Button copy is a type of physical design for
Button copy has been supplanted by a newer technology: retroreflective sheeting made by various manufacturers in numerous colors and grades.[1] As state departments of transportation increasingly stopped specifying button copy signs in favor of signs made with sheeting, it became uneconomical to maintain production of the materials and supplies for making button copy signs. The last state to specify button copy signs was Arizona, which switched to sheeting in 2000.[2]
The advantage of button copy is durability, in that a well-made button copy sign has a service life of around 40 years.[3] In contrast, signs made out of retroreflective sheeting are expected to last only around 15 years.[3] However, at night, retroreflective sheeting is clearly visible and readable at much longer distances than button copy.[dubious ]
