A notice indicating that a device or system is not functioning correctly, produced via a printing process, serves to inform individuals of its unavailability. For example, a printed sign placed on an elevator door stating it is temporarily non-operational. This communicates that the lift cannot be used until further notice.
The creation and display of such alerts are crucial for maintaining safety and managing expectations within various environments. It prevents misuse, potentially averting damage or injury, and improves communication by clearly stating the current status of the equipment or service. Historically, the dissemination of this information has relied on various formats, evolving from handwritten notes to standardized, machine-produced notices.
The following sections will explore the design considerations, material selection, and optimal placement strategies for effectively communicating equipment malfunctions through visual means. Further analysis will focus on the specific contexts where these printed notices are most beneficial and how technological advancements are impacting their evolution.
