Abstract
A printer is configured to print a color target that associates colors to which humans are most sensitive to color variance with areas of the color target within which color measurement is less prone to meassurement error. The printer then prints the color target according to the association. In an optional impemementation, measurements of like color elements within the target are average. In a further optional impementation, the averaging is performed using weighted values, wherein the weighting is based on color measurement accuracy within an area within the color target wherein each measured element is located. In a still further implementation, a color look-up table is generated according to measurements made of the color target.
