Abstract
A system that allows a user to tune a designated a color profile for a specific color input or output device thereby creating a device specific profile from a profile for a similar device or from a generic device profile. The color values associated with the device, either patches input to a scanner or patches output by a display or a printer, are measured using a colorimetric color measuring device. These measured values are used to adjust or tune the profile to produce a more accurate profile for the particular device. The adjustment includes curve fitting the measured color values and simulated color values to create a mapping from the measured values to the simulated values. The curve is used to adjust the profile. To account for gamut shifts the color values can be mapped into the gamut of the device during tuning curve creation.
