What is blueprints?
A blueprint is a replica of a technical design or engineering drawing made on light-sensitive paper using the contact print method. The procedure, which was first developed by Sir John Herschel in 1842, allows for the quick and precise manufacture of an infinite number of duplicates. It has been frequently used for more than a century to replicate specification drawings used in industry and construction. A negative of the original, the blueprint process was represented by white lines on a blue backdrop. Colors and grayscales could not be accurately reproduced by the method.
The method is now out of date. Major-format xerographic photocopiers eventually replaced it in large part after being mainly replaced by the diazo whiteprint process.
