Yes..! With us, you are receiving a Real Blueprint!
__________Three feet
wide plus generous borders_________
For many... the term blueprint is used
loosely to describe copies of original drawings or tracings.
What is a Blueprint...
Formed by light-sensitive iron salts,
the blueprint process is
characterized by white lines on a distinctive blue background that
can range from deep to moderate in intensity. It relies on two
classes of compounds. The paper is light sensitized with a mixture
of a diazonium salt (used in the manufacture of dyes), a reactant
and an acid that keeps the diazonium salt and the reactant from
reacting with each other.
A designer or draftsman first
makes an original drawing on tracing paper or clear, colorless
plastic. This tracing is placed over chemically modified
blueprinting paper and exposed to ultraviolet light. Light destroys
the diazonium salt. Ammonia gas or solution is used as a developer
after exposure -- it neutralizes the acid and allows the remaining
diazonium salt to combine with the reactant to create a blue dye.
The nearly completed Blueprint is then
heated to stabilize the
compounds and remove any residual chemicals. The result is a blue
sheet of paper with white lines, called a blueprint.
Aside from alkaline and extended
exposure to direct sunlight, blueprints are as stable as the paper
on which they are printed.
-
Blueprinted images
are permanent.
-
Prussian Blue,
the pigment that gives the Blueprint its color is impregnated deep
within the paper fibers.
-
Unlike some
of the more common printing methods, the image cannot be scratched
or rubbed off. Prolonged exposure to UV light (i.e. direct sunlight) will
result in a change of color. Display your design drawings so that they will not
be exposed to direct sunlight.

The Lost
Art of Blueprinting
In the liquid state,
some of the chemicals Blueprinters require are labeled as hazardous.
Shipping costs have thus escalated, forcing the advent of much faster and
cheaper printing methods. "True Blue" Blueprinting is now mainly reserved for
the purist. Why settle for anything less? |
