Cyanotype is a photographic printing process that produces a cyan-blue print. Engineers used the process well into the 20th century as a simple and low-cost process to produce copies of drawings, referred to as blueprints.

Are Cyanotypes still used today?
Cyanotypes are still used today as an alternative printing medium; however, during the 20th century, as photography and technology advanced, the technique became somewhat obsolete. It reverted to primarily being used for replicating architectural diagrams and design notes—aka blueprints.
