fotomekanisk

Fotomekanisk refers to a process or technology that combines photographic principles with mechanical operations. Historically, this term has been used in various contexts, most notably in printing and reproduction. In the realm of printing, photomechanical processes revolutionized the way images and text were transferred onto printing plates. Instead of purely manual engraving or typesetting, these methods utilized light-sensitive materials and photographic techniques to create the printing surface. This allowed for greater accuracy, speed, and the faithful reproduction of detailed images, including photographs themselves.

Early photomechanical printing methods included techniques like photogravure, collotype, and halftone printing. These processes involved exposing a light-sensitive coating on a plate or cylinder through a photographic negative or positive. The exposed areas would then harden or become soluble, allowing for the etching or inking of the image. This facilitated the mass production of illustrated books, newspapers, and magazines.

The term "fotomekanisk" can also be applied more broadly to any system where light is used to control or initiate a mechanical action. This could encompass certain types of automation, sensors, or even older forms of optical control systems where light beams triggered mechanical switches or movements. While modern digital technologies have largely superseded many traditional photomechanical processes, the underlying principles of using light to influence mechanical outcomes remain fundamental to many contemporary technologies.
