Where did blueprints originate?
Way back when, the way to copy drawings was to lay a sheet of tracing paper or other sufficiently transparent medium over the original and trace it. A process was developed in the nineteenth century that yielded a copy with the image in white lines on a blue background, which is where the name “blueprint” came from.
When was blue blueprints invented?
1842
Ever wondered where the “blue” came from in blueprints? These documents actually obtained their trademark blue in 1842 when John Herschel discovered the cyanotype process. Artists and scientists quickly adopted this new way to reproduce notes, efficiently and at a lower cost than previous methods available.
When did blueprints stop being blue?
1940s
Once the drawing was exposed to light, the exposed parts turned blue, while the drawing lines blocked the coated paper from exposure and remained white. One hundred years later, in the 1940s, blueprints were replaced by diazo prints, aka whiteprints or bluelines. Diazo prints had blue lines on a white background.
Why is a blueprint blue?
The blueprinting paper, which is still white, is placed in an aqueous solution of potassium ferricyanide. This compound reacts with ammonium ferrous citrate and forms a compound called prussian blue. This compound, in it’s hydrated form, is blue.
Which gas is used to make blueprint?
Ammonia gas is used as a developer in diazotype method to make blue prints.
When did we stop using blueprints?
Traditional blueprints became obsolete when less expensive printing methods and digital displays became available. In the early 1940s, cyanotype blueprint began to be supplanted by diazo prints, also known as whiteprints.
Why do they call it blueprint?
The reaction from the sun causes a compound to appear on the paper called blue ferric ferrocyanide, or Prussian Blue. This is the blue color left behind on the treated paper and why these copied documents came to be known as blueprints.

When was the first blueprint ing process invented?
Blueprint ing, the first economical method for duplicating drawings, was invented in 1842 and introduced in the United States in 1876. The diazo process, xerography, and computer-controlled drafting machines have more recently shared this function. The availability of numerous copies of drawings facilitated the division of…

Blueprinting, the first economical method for duplicating drawings, was invented in 1842 and introduced in the United States in 1876. The diazo process, xerography, and computer-controlled drafting machines have more recently shared this function.
When was the service blueprint first used in business?
Service blueprint. The service blueprint is a technique originally used for service design and innovation, but has also found applications in diagnosing problems with operational efficiency. The technique was first described by G. Lynn Shostack, a bank executive, in the Harvard Business Review in 1984.
Who is considered to be the father of blueprints?
In fact, architect and engineer Filippo Brunelleschi used the camera obscura to copy architectural details from the classical ruins that inspired his work. Today, Brunelleschi is considered to be the father the modern history of blueprints.
What are the facts on blueprints?
A blueprint is a reproduction of a technical drawing or engineering drawing using a contact print process on light-sensitive sheets . Introduced by Sir John Herschel in 1842, the process allowed rapid and accurate production of an unlimited number of copies. It was widely used for over a century for the reproduction of specification drawings used in construction and industry.
What are blueprints used for?
Blueprints, in the traditional sense, are used by architects and engineers to design and build new things. They are used to ensure that the final products are built to specifications and in compliance with certain standards and requirements. Azure Blueprints are used in much the same way as traditional blueprints are.
Why are blueprints blue?
When the two papers are exposed to a bright light, the two chemicals react to form an insoluble blue compound called blue ferric ferrocyanide (also known as Prussian Blue ), except where the blueprinting paper was covered, and the light blocked, by the lines of the original drawing.
