1. A method for generating a color characterization model for performing transformation from a device-dependent color space of a color device to a device-independent color space, the method comprising the steps of: accessing a first set of color measurement data corresponding to actual measurements of the color device, wherein the actual measurements define a measurement range in the device-dependent color space, and wherein the measurement data includes data point pairs, each data point pair having corresponding device-dependent values and device-independent values; generating a second set of data point pairs based on a predesignated set of device-dependent values outside the measurement range, by extrapolating device-independent values from the first set of color measurement data; and determining the color characterization model based on both the first set of color measurement data and the generated second set of data point pairs.
