Color printing
When color printing is known in the printing art , a printing method , wherein a plurality of inks are used, but also individual prints produced by means of color printing. From the three basic colors cyan , magenta and yellow ( CMY model ), many shades of color can be represented on the paper. However, this three-color process is only used in a few applications, such as inkjet printers . Black is also required for the contrast .
One distinguishes
- the four-color printing , in which the CMY model by black (K = contrast) to the CMYK color model is extended. With wet-on-wet printing, the black is applied first so that the contrast is retained in the image,
- the six-color printing , in which as an additional print colors green and orange are added. This process is developed by the Pantone company and sold under the product name Hexachrome .
- the multi-color printing with various defined spot colors .
In contrast to the spot colors, the basic colors are also referred to as process colors . In offset printing, color gradations are created by screening . A color separation must take place beforehand .
Chromolithography , patented by Godefroy Engelmann in 1837 , became important in the history of industrial color printing . It was the common method for high quality color illustrations until the 1930s.
