The Origin of the Blueprint


The replication of documents, though easy today, was a time-consuming and tedious task that had to be conducted by hand. The blueprint services available to you in Tampa Bay have advanced a long way from those originally created by English photographer and chemist, John Herschel.


Herschel discovered that a chemical reaction and subsequent compound called blue ferric ferrocyanide occurred when combining ferric ammonium citrate and potassium ferricyanide. In simple terms, this chemical reaction could be used to Blueprint Services | Tampa Bay | LDI Signs & Printingreproduce documents in a similar fashion to the reproduction of the film.

From there, a process called cyanotype was adopted. A drawing is created, traced onto vellum paper, and then saturated in an ammonium potassium mixture, and finally, it’s dried. Once the dried paper is exposed to bright light, a transformation occurs. The paper turns Prussian blue due to the blue ferric ferrocyanide. This process was much less costly than the manual reproduction of documents and was quickly embraced by engineers and architects.


Modern-Day Blueprints


Today, digital blueprint services make this process easier, but the blue hue remains on many blueprints. Computer Assisted Design (CAD) drawings have greatly simplified the act of creating blueprints and construction drawings, as has a process called diazo—whiteprinting—where the images are a positive, rather than a representation of a negative image. Photocopiers and the whiteprint process have largely replaced the cyanotype process, but the name and color often remain in modern blueprint services in Tampa Bay.
