The act of photocopying: its origins, working and wide-ranging impact
Subject : Polity
Section: Legislations in news
Introduction:
- In his essay “The Work of Art in the Age of Mechanical Reproduction,” the German philosopher Walter Benjamin underscores how mass reproduction affects art within a capitalist society.
- The advent of xerography, a dry photocopying method, revolutionized the way textual material is reproduced and disseminated.
- Xerography’s impact extends beyond simple reproduction to copyright, surveillance, counterfeiting, and even the art scene.
What is photocopying?
- Broadly, photocopying is a set of techniques used to duplicate content using, among other things, light.
- However, the contemporary colloquial use of the word ‘photocopying’ refers almost exclusively to xerography. Both the word ‘xerography’ and the name ‘Xerox’ come from the Greek root word ‘xero’, meaning ‘dry’.
Understanding Xerography
- Xerography, derived from the Greek word “xero” (meaning dry), involves a photocopying technique that doesn’t require liquid chemicals.
- In xerography, a photoconductive surface is negatively charged, exposed to light, and used to duplicate printed material.
- A powdery substance called toner is applied to the charged surface, transferred to a sheet of paper, and heated to create a copy.
Invention of Xerography
- Inspired by Hungarian engineer Paul Selenyi, American attorney Chester F. Carlson developed xerography in 1938.
- Carlson sold his idea to the Battelle Memorial Institute in Ohio, where researchers refined the technique.
- The New York-based Haloid Photographic Company purchased a licence from Battelle and introduced the first Xerox machine in 1949.
Impact of Xerography
- Counterfeiting: Xerox machines have mechanisms to prevent the photocopying of banknotes with specific markings, making counterfeiting more challenging.
- Copyright and Education: Xerography enabled the reproduction of educational material at a low cost, benefiting students and institutions. It has also raised questions about copyright infringement.
- Art and Creative Expression: Xerography empowered artists, musicians, and writers to self-publish, advertise events, and explore their creative expressions outside traditional galleries and museums.
