Blueprint Photo Article For Free

A blueprint is defined as a copy of a building or engineering plan, reproduced with white lines on a blue background, or detailed plan of action. An example of a blueprint is a construction worker's diagram of building plans for a new home.

In blueprinting, the older method, the drawing to be copied, made on translucent tracing cloth or paper, is placed in contact with paper sensitized with a mixture of ferric ammonium citrate and potassium ferricyanide, which is then exposed to light.

It was widely used for over a century for the reproduction of specification drawings used in construction and industry. 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.

A blueprint is a two-dimensional set of drawings that provides a detailed visual representation of how an architect wants a building to look. Blueprints typically specify a building's dimensions, construction materials, and the exact placement of all its components.

Technical drawings of architectural or engineering designs always seem to consist of white images and text on blue paper.The technique was faster and more cost-effective than hand-tracing original documents, and caught on as an easy, inexpensive way to reproduce drawings and texts.

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.

Allow the sheet of blueprint paper to dry, coated side up, in the dark.If you do not rinse away any unreacted chemicals, the paper will darken over time and ruin the image. However, if all the excess chemicals are rinsed away, you'll be left with a permanent colorfast image of your object or design.
