service and price for reprography and blueprint. Let’s talk about
the history of blueprint service first:
A blueprint is a type of paper-based reproduction usually
of a technical drawing, documenting architecture or an engineering design.
More generally, the term "blueprint" has come to be used to
refer to any detailed plan.
Various base materials have been used for blueprints. Paper was a common
choice; for more durable prints linen was sometimes used, but with time,
the linen prints would shrink slightly. To combat this problem, printing
on imitation vellum and, later, polyester film (Mylar) was implemented.
Traditional blueprints have largely been replaced
by more modern, less expensive printing methods and digital displays.
In the early 1940s, cyanotype blueprint began to be supplanted by diazo
prints or whiteprints, which have blue lines on a white background;
thus these drawings are also called blue-lines or bluelines. Other comparable
dye-based prints are known as blacklines.
Diazo prints remain in use in some applications but in many cases have
been replaced by xerographic print processes similar to standard copy
machine technology using toner on bond paper. More recently, designs
created using Computer-Aided Design techniques may be transferred as
a digital file directly to a computer printer or plotter; in some applications
paper is avoided altogether and work and analysis is done directly from
digital displays. Another common modern method of copying is the use
of large-format scanners. These digitize an image which can then be
printed with a large-format plotter.
As print and display technology has advanced, the traditional term "blueprint"
has continued to be used informally to refer to each type of image.
