Full color copy

from Wikipedia, the free encyclopedia

The full-color copy is a photocopy that is made with the four basic colors cyan , magenta , yellow and black (depth) and is therefore suitable, for example, for the reproduction of color photos. In the late 1980s, full-color photographic copiers that reproduced the original on color photographic paper were also common. In the 1980s and 1990s, the term full color copy differentiated these devices from photocopiers, which had one or more spot colors (such as green or brown) in addition to black toner and were therefore able to make copies of this color, but were not suitable for copying color originals - they were simply called color copiers or spot color copiers.

Full color copying processes were originally divided into analog and digital processes. The analogous processes included photographic processes (divided into silver color bleaching processes and chromogenic processes; both output on photo paper; like color photos - therefore only one-sided), the Cycolor process (a special process that converts the four from a transfer film covered with so-called Cyliths Basic colors transferred) and analog electrophotographic processes (the principle of classic photocopy). The analog processes can hardly be found today. The digital processes include digital electrophotographic processes and inkjet processes, as well as thermal transfer processes (less common). The first digital full-color copiers (around 1990) were closed systems: scanner and printer sections were combined in one housing and could not be controlled externally. Today's devices allow the use of these devices as a scanner and printer (connected to a PC or a network) or the use for direct copying like a conventional photocopier through interfaces (= plugs). Special devices allow full color large format copies (first device around 1990: Canon Bubblejet A1 Copier).
