In dry imaging systems, which factor is used to develop the latent image on film?

• A. Heat
• B. Chemicals
• C. Light
• D. Pressure

Answer: (A)

Developing a latent image in dry imaging relies on heat as the trigger. In dry systems, the exposure creates a latent pattern in the film, and instead of immersing the film in chemical developers, heat activates a built-in, heat-sensitive process that converts the exposed areas into a visible image. This approach eliminates liquid chemicals and speeds up development. Light would not serve to develop in this scheme, and pressure isn’t the mechanism used to form the image, while chemicals would defeat the “dry” concept.
