A solution of potassium ferricyanide is used to develop the image – this forms an insoluble ferroferricyanide (Prussian blue or Turnbell’s blue) – and then the excess chemicals are washed off. Upon exposure to light, a photoreaction occurs turning the trivalent ferric iron into divalent ferrous iron. The sheet is then saturated with ammonium ferric citrate solution and dried. The blueprint process starts off with a photosensitive ferric compound, usually the widely used ammonium ferric citrate and potassium ferricyanide. The blueprints presented as negative drawings or illustrations of the original as white lines on a blue background.
