A blueprint is a reproduction of a technical drawing or engineering drawing using a contact print process on light-sensitive sheets.It was widely used for over a century for the reproduction of specification drawings used in construction and industry.

Blueprints use the cyanotype process invented by the astronomer John Herschel in 1842. The paper is coated with a solution of two soluble iron(III) salts. The two iron salts do not react with each other in the dark, but when they are exposed to ultraviolet light the iron(III) ammonium citrate becomes an iron(II) salt.

What is the standard blueprint paper size? Blueprints and house plans will come in several standard sizes. Two of the most common architectural drawing sizes are 18 x 24 and 24 x 36, but you can also find them in 30 x 42 and 36 x 48 sizes.
