Abstract
In a settable matrix photographic color printer, Neutral, Green-chromaticity, and Illuminant-chromaticity correction levels and associated color rotations are adjusted by: transforming the printer correction matrix from a Red, Green, Blue coordinate system to a Neutral, Green-chromaticity, Illuminant-chromaticity coordinate system whereby the diagonal elements of the transformed matrix represent the Neutral, Green-chromaticity, and Illuminant-chromaticity correction levels, and the off-diagonal elements of the matrix represent color rotations; changing the value of the elements of the transformed matrix as desired; and transforming the thus adjusted matrix back into the Red, Green, Blue color coordinate system.
