Color Reproduction
Substractive primary color inks are transferred to the paper when the plates made from the separation negatives are printed. Magenta ink is printed by the plate made from the green separation negative. Yellow ink is printed by a plate madefrom the blue separation negative.
Process color prints are made by printing yellow, magenta, and cyan plates in perfect register on a single sheet of paper. By controlling the amounts of yellow, magenta, and cyan inks, you can produce all other colors of the visible spectrum.
In theory, only the three substractive primary colors of ink are necessary to reproduce all colors of the spectrum. This is not true in actual practice, however. A forth ink, black is needed to improve the grays and shadows in the print.
