DEVICE INDEPENDENT COLOR CONTROLLER AND METHOD

A method of correcting for error in an output color of a colored output image in a marking device intended to match a desired image includes the steps of detecting a current output color in the output image with a color sensing device, determining a difference between the current output color and a corresponding target color under standard conditions, and automatically setting a marking device input-output relationship for a next output color based on the difference between the current output color and the corresponding target color under standard conditions to minimize the difference between the next output color and the corresponding target color.
