Kopiopainatus

Kopiopainatus, also known as photocopied printing or simply copying, refers to the process of reproducing documents using a photocopier. This technology became widespread in the latter half of the 20th century, offering a convenient and relatively inexpensive way to create duplicates. The fundamental principle behind photocopier technology is the use of an electrostatic charge to transfer toner particles onto paper. Light is used to create an image on a charged drum, and where the light hits, the charge dissipates. Toner, which is attracted to the charged areas of the drum, is then transferred to the paper and fused into place with heat and pressure.

Early photocopiers were often bulky and produced lower quality results, but advancements have led to increasingly sophisticated machines capable of high-resolution printing, color reproduction, and various finishing options. The term "kopiopainatus" emphasizes the direct duplication aspect, distinguishing it from methods like offset printing which involve plates and are typically used for larger print runs. While digital printing technologies have become dominant for many applications, photocopiers remain a common sight in offices, libraries, and homes for on-demand document reproduction. Their ease of use and immediate results contribute to their continued relevance.
