Blueprint Phone Paper For Free

The blueprint process uses a photosensitive ferric compound, which allows the image to be printed on a piece of paper. It is then dried and developed by using a solution that gives it a distinctive blue color. It's a relatively simple process, and it has several features that made it useful.

In this process, initially created just to transfer notes, two papers are exposed to a bright light, and the applied chemicals create a permanent blue compound, called blue ferric ferrocyanide, except for where the paper is covered or has lines drawn. As a result, a solid-blue document with white lines is created.

Paper: 20 lb, 24 lb and 32 lb papers are commonly used for blueprint printing, and they are suitable for both black and white and color printing. Besides these, 20 lb color papers are also used, although they are only suitable for black and white prints.

In a very dim room or in the dark: pour the potassium ferricyanide and iron(III) ammonium citrate solutions together into a petri dish. Stir the solution to mix it. Use tongs to drag a sheet of paper across the top of the mixture or else paint the solution onto the paper using a paintbrush.

Blueprints use the cyanotype process invented by the astronomer John Herschel in 1842. The paper is coated with a solution of two soluble iron(III) salts - potassium hexacyanoferrate(III) (potassium ferricyanide) and iron(III) ammonium citrate.

A blueprint's signature hue is tied to a chemical process. In 1842, an English photographer, chemist and astronomer named John Herschel discovered that combining ferric ammonium citrate and potassium ferricyanide created a chemical reaction and a compound called blue ferric ferrocyanide (or Prussian blue).

The blueprint process is based on a photosensitive ferric compound. The best known is a process using ammonium ferric citrate and potassium ferricyanide. The paper is impregnated with a solution of ammonium ferric citrate and dried.

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.

Vellums are used to make high quality copies of blueprints. The vellum we carry is made from 100% cotton. It is an excellent choice for presentation quality work and archiving.
