Meaning of Xerography

What is Xerography:

Xerography is a procedure or mechanism to copy documents through dry electrostatics. It is also the copy or document obtained by this procedure, although in general the word "photocopy" is used.

This word with the Greek terms is formed with xero- Y -graphy, adaptation of xerox (dry) and graphein (writing).

It also exists as a verb: "xerografiar", although in Spanish it is more common to use "make or take photocopies" or "photocopy". Xerography uses a photoconductive material to form a printed image. This material is a poor conductor or insulator in the dark but when exposed to light it improves its electrical conduction properties.

This procedure is very popular and has many advantages due to the ease and low cost with which documents can be reproduced. In turn, it can lead to problems in relation to the reproduction and use of copyrighted documents or secret and confidential information. History of xerography The first xerography dates from 1938 by the American physicist and inventor Chester Carlson. The first document in History to be xerographed had the following inscription 10-22-38 ASTORIA. Indicating the date (October 22, 1938) and the place (Astoria, where Chester Carlson's laboratory was located, in New York, United States).

In the beginning, xerography was known as electrophotography. Later, it received the commercial name of xerography. The term "xerox" distinguished this type of dry copying procedure from other document copying mechanisms. The use of xerography has spread from the 60s onwards.

Currently, there are several companies that manufacture xerographic machines or photocopiers. Many companies and institutions have photocopiers and there are many businesses that make copies of documents.

Xerography and reprography

Reprography is the reproduction of documents or images through mechanical or electrical means, such as photography. Xerography, therefore, also fits into this category, the word "reprography" being a broader concept. Photocopying businesses are commonly called reprography.

Xerography and screen printing

Screen printing should not be confused with xerography. It is also a printing process, although much older than xerigraphy. It consists of the application of ink on a material through a mesh (formerly, silk). The uses in which screen printing is applied are very varied, as in the world of Advertising, since it allows the printing of images or texts at a relatively low cost. Screen printing can be done on various materials, both natural (for example, cork or wood) and artificial (plastic, canvas ...)
