Abstract: An imagesetting system includes: an imagesetter for photographically recording an image onto media; a wet chemical processor, proximately positioned adjacent to the imagesetter, for receiving and processing the imaged media, and a light-tight control wedge box containing a test strip to be processed by the wet chemical processor, without physically separating the imagesetter and the processor, to indicate whether chemicals in the wet chemical processor are depleted below a level of effectiveness. The imagesetting system operates in a test mode to determine whether chemicals in the processor are depleted below the level of effectiveness.
