What did the original blueprint look like?

The blueprint process was characterized by white lines on a blue background, a negative of the original. The process was not able to reproduce color or shades of grey. The process is now obsolete. It was first largely displaced by the diazo whiteprint process, and later by large-format xerographic photocopiers.

Are blueprints still blue?

And, by the 1980s, the architecture, engineering and construction industries were making the move from hand-drawing to computer-aided design (CAD) that could be printed on large-scale paper. Today, “blueprints” aren’t really blue. They are usually black or gray lines on a white background [source: Soniak].

How are blueprints drawn today?

Today, the blueprint of the future is digitally based. Although the construction industry is still widely paper-based, this is changing quickly. Now, with cloud-based document control solutions, digital drawing files are distributed instantaneously from office to the field.

How were blueprints originally created?

​Blueprints were invented a generation before the Civil War by John Herschel, a chemist, astronomer, and photographer, in 1842. Herschel developed the cyanotype process that started with a drawing on semi-transparent paper, weighted down on top of a sheet of paper. To this day, they are often called blueprints.

Why do blueprints use blue?

It’s because of how those documents are made. The blueprinting process was developed in the mid-1800s, when scientists discovered that ammonium iron citrate and potassium ferrocyanide created a photosensitive solution that could be used for reproducing documents.

Why is it called a blue print?

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.

Where did blueprints originate and where are they evolving today?

In today’s construction industry, before anything is built, it’s dreamed, drawn and planned in the form of blueprints. These documents are truly the foundation of any construction project but they have been around for some time now. So, where did blueprints originate from and where are they evolving today?

Is the blueprint of the future still paper based?

As a result, a huge drain on manpower and resources is created, not to mention the inevitable rework needed when an outdated set slips through the cracks. Today, the blueprint of the future is digitally based. Although the construction industry is still widely paper-based, this is changing quickly.
