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.
State transportation departments began preferring signs made from sheeting over button copy signs, leading to increased costs for producing materials and supplies related to button copy signs. Arizona was the final state to use button copy signs, switching to sheeting in 2000.
