Can you suggest some approaches to building a darkroom for a screen-printing shop that has a limited floor space? This was a question posed by a Printwear reader, and here is Kieth Stevens’ response:

A booth can often be constructed of black plastic sheeting, which is relatively cheap to purchase. Choose a location close to the washout area to minimize exposure to light. Simply construct a 1′ x 3′ wooden frame and determine where to place the entry to the dark room. Staple the plastic to the frame and overlap some plastic to create the “door.” By overlapping the plastic sheets, it will minimize the light coming through during entry and exit. Also, be sure that the plastic cover reaches to the floor to block out light completely.
