The printing process is a collection of other discrete processes all needed to produce the end product; typically an image on paper. In reproducing a full, or four-color image a photograph is separated into four components represented on film. One film is produced representing the amount of cyan found in the image, one for the amount of magenta, and one for the amount of yellow. A fourth film is produced which represents the black portion of the photograph which typically is wherever cyan, magenta, and yellow are all present in equal amounts. In order to simulate varying amounts of a given color found in a photograph, we use dots that change diameter or total coverage. For example, if we took one spot on a photograph and broke it down into its various components we may end up with something like this :
Black =20 % Cyan =40 % Magenta =40 % Yellow =20 %
