A contact print of a drawing or other image rendered as white lines on a blue background. A blueprint is generally a print of an architectural plan or technical drawing and is often used for construction purposes or obtaining permits.

A type of print used for copying engineering drawings and similar material. The name is popularly applied to two separate methods, more exactly designated as the blueprint and the whiteprint, or diazotype. In blueprinting, the older method, the drawing to be copied, made on translucent tracing cloth or paper, is placed in contact with paper sensitized with a mixture of ferric ammonium citrate and potassium ferricyanide, which is then exposed to light. In the areas of the sensitized paper not obscured by the lines of the drawing, the light reduces the ferric salt to the ferrous state, in which it reacts with the potassium ferricyanide to form insoluble prussian blue. The exposed paper is then washed in water, producing a negative in which the lines of the drawing appear in white against a dark blue background.

Any of the prints made by the Ozalid process (the image can be blue, black or brown).

Architectural plan used to build a home or other structure.

A plan of a building in such detail as to enable workmen to construct it from the print. The name comes from the photographic process which produces the plan in white on a blue background.
