Our dark room is sectioned off almost into 2 rooms. One is the cts/computer and exposure unit, other is coating room.
The coating room has 2 doors that hold 2 screen racks for drying, has a heater and dehumidifier is just outside it. It also has an exhaust.
Basically the room is 30-40% humidity and the drying cabinet is like 15%, 85 degrees, lots of air movement.
