fénymásolatok

Fénymásolatok, often referred to as photocopies or xerographic copies, are reproductions of documents or images created using a dry copying process. This technology, pioneered by Chester Carlson and commercialized by Xerox, became widespread in the mid-20th century. The process relies on the principle of electrostatics. An image is projected onto a charged, light-sensitive drum, causing the charged areas to lose their charge where light strikes them. A dry, powdered ink, called toner, is then attracted to the remaining charged areas on the drum. This toner image is transferred to a sheet of paper, which is then heated to fuse the toner permanently onto the surface, creating the copy. Fénymásolatok offer a quick and relatively inexpensive method for duplicating paper-based materials. They are commonly found in offices, libraries, and print shops. While digital scanning and printing have become increasingly prevalent, fénymásolatok remain a practical solution for many everyday copying needs due to their simplicity and immediate results. The term itself is derived from Hungarian, with "fény" meaning light and "másolat" meaning copy.
