DIAZOTYPE Meaning and
Definition
-
Diazotype, also known as whiteprint or blueline print, is a method of reproducing engineering or architectural drawings. It involves producing copies of original black-and-white line drawings, typically on blue or white background paper.
The process of creating diazotype prints involves the use of photosensitive chemicals. A master copy of the drawing is placed on top of a light-sensitive paper coated with diazo compounds. When exposed to ultraviolet light, the diazo compounds change their chemical composition and become reactive. This creates a stencil-like image, with the portion exposed to light becoming blue or black, while the rest remains white or blue.
The resulting diazotype copy is characterized by its high contrast, clear lines, and distinct blue or white background. It is commonly used in the field of architecture, engineering, and design, as it can accurately reproduce technical drawings and intricate details.
Diazotype prints offer advantages such as quick reproduction, low-cost production, and the ability to produce large-format prints. They are also highly durable and resistant to fading, making them suitable for long-term archival purposes.
While diazotype was widely used in the past, the advent of digital printing and photocopying technologies has largely rendered it obsolete. However, diazotype prints still retain some niche applications in industries where precise reproduction of technical drawings is required.

Etymology of DIAZOTYPE
The word "diazotype" is derived from two components: "diazo" and "type".
1. "Diazo": The prefix "diazo" originated from the Greek word "diazō", which means "to dye". It was introduced into English in the mid-19th century and refers to a chemical compound containing two nitrogen atoms linked by a double bond (N=N), often used in the production of dyes or photographic processes.
2. "Type": The term "type" comes from the Latin word "typus", which later entered Middle English from Old French. In general, "type" refers to a kind, sort, or category of something. In the context of the word "diazotype", it specifically pertains to a photographic or printing process.
