A photostatic copy It is the exact reproduction of a document or graphic image through methods known as photo opticians. It is usually known commonly as a photocopy, and it can be done through the taking of a photograph and the subsequent reproduction of this through printing.
In the past, documents were photographed and developed on photographic paper. It was the most effective method for the reproduction of a document, being known as photostatic.
Gradually, the process was perfected, due to the low quality of the results and the high cost of development..
When a photographic reproduction of an image is made directly on paper, we are in the presence of photostatics.
Any procedure that links the capture of an image for its subsequent exact reproduction, classifies as this practice.
It was the name of the artifact used to perform this photostatic procedure in the past. It was widely used by large organizations that deserved the reproduction of documents on a large scale.
The invention of the mimeograph is attributed to Thomas Alva Édison, who patented the artifact in 1887. The same year, Edison sold the artifact to Albert Blake Dick, who would be responsible for its reproduction..
Starting from Edison's idea, Chester Carlson patented in 1938 an artifact that could make exact reproductions of documents by working on paper..
It would not be until 10 years from now when it would begin to be marketed by the family business Haloid Company, which would later become Xerox. In 1947, the first photocopying machine in the world would see the light.
The surface of the cylindrical drum made with the photoconductive material is loaded. This is activated when exposed to light.
A lamp illuminates the document and the white areas reflect the light onto the cylindrical drum. Black areas remain while white areas are discharged.
When working with toner, it is positively charged. Then, through the electrostatic process, it is fixed corresponding to the black areas of the cylindrical drum.
The paper is negatively charged and the toner is transferred to the paper.
Toner melts into paper through pressure and heat.
-After its evolution, it has contributed to cost reduction by being able to be reproduced on low-quality paper.
-Thanks to photostatics, it has been possible to preserve copies of historical documents that time has deteriorated to the point of almost making them disappear..
-Due to its speed and simplicity, it is very easy to make copies of important books and documents for later distribution..
-It is an assembly process that does not require a high level of preparation, so anyone can reproduce a document through this method..
-Allows original documents to be archived and replaced with copies, reducing the chances of loss and damage of important documents.
-Original documents do not need to be created again, they can be reproduced through photostatics for duplication.
