What does blueprint mean?
A blueprint is a detailed plan or drawing that specifies how something should be built, made, or accomplished. The term originated in nineteenth-century architectural practice, when copies of technical drawings were made by a photographic contact-printing process that rendered them as white lines on distinctive deep-blue paper. Although modern plans are now digital and printed in other formats, 'blueprint' remains the standard term for such documents in architecture, engineering, and construction. The word has also acquired a strong figurative meaning: any carefully worked-out scheme or template intended to guide future action, as in 'a blueprint for economic recovery' or 'the blueprint for her career.' In this extended use it carries connotations of thoroughness, foresight, and authority — a blueprint implies not just an idea but a complete, actionable design. Both the literal and figurative senses appear constantly in news, business, and everyday speech, making the word a versatile staple of English vocabulary.
A detailed technical drawing or plan, especially one used in building or manufacturing; also, figuratively, a comprehensive plan or model for future action.
"The city council approved the blueprint for the new library."
The figurative sense is fully established and common in political and business discourse.
To draw up or prepare a detailed plan for something; to design or map out in advance.
"They blueprinted the entire expansion before seeking funding."
Standard regular plural; used for both physical drawings and figurative plans.
"The archive holds thousands of blueprints from the shipyard's heyday."
The original blueprints were literally blue: white lines on Prussian-blue paper produced by an 1842 photographic copying process invented by astronomer John Herschel.

Etymology of blueprint
Blueprint combines 'blue' with 'print', the latter from Old French 'preinte', based on Latin 'premere' ('to press'). It arose in the mid-nineteenth century after John Herschel's 1842 cyanotype process made cheap photographic copies of drawings possible, producing the familiar white-on-blue images. As digital drafting replaced cyanotype copies, the word survived both literally for technical plans and figuratively for any master plan or template.
