Photostats refer to copies or reproductions of documents or images created through the process of photostatic printing. The term "photostat" can be used as both a noun and a verb.
As a noun, photostats are black-and-white photographic copies of original documents or images produced by using a photostat machine, which was a type of duplicating machine widely used before the advent of modern photocopying technology. Photostat machines operated by exposing the original document or image to light-sensitive paper or film, resulting in an exact replica of the original. These copies were typically the same size as the original, providing an accurate reproduction of the content.
As a verb, to "photostat" means to produce a copy or replica of a document or image using a photostat machine. The process involves placing the original document on the glass surface of the machine, which then exposes it to light, creating a photographic reproduction on sensitized paper or film.
The term "photostats" can also be used to refer collectively to a collection or set of such copies. In an archival context, "photostats" can denote a series of important historical documents that have been copied through the photostatic printing process for preservation and accessibility purposes.
Though photostat technology has become obsolete with the advent of digital scanning and photocopying, the term "photostats" is still used to refer to historical copies or reproductions that were made using photostatic printing methods.
The word "photostat" is derived from the combination of two separate terms: "photo" and "stat".
The term "photo" comes from the Greek word "phōs" (φῶς), which means "light". It is commonly used as a prefix in words related to light, such as "photography", "photon", and "photosynthesis".
The term "stat" is a shortened form of "stationery", which originally referred to paper and other office supplies used in an office or stationary shop.
"Photostat" was originally a trademarked name for a machine invented in the early 20th century by the Photostat Corporation, which allowed for the reproduction of documents by photographic means. Due to its popularity and widespread use, the term "photostat" eventually became a genericized trademark for any similar reprographic process.
