First Claim
1. A color management method for constructing a device model for a device, wherein the device model is constructed for use in a measurement-based color management system, the method comprising the steps of:
- accessing a transform-based color profile for the device which contains a color transform for transforming color data from a device-dependent color space to a colorimetric device-independent color space, wherein the transform-based color profile is designed for use in a transform-based color management system;
computationally generating color measurements for use in the measurement-based color management system by computationally transforming a plurality of predetermined color samples by using the color transform contained in the transform-based color profile; and
constructing the device model for the device by using the computationally generated color measurements, wherein the device model transforms color data from the device-dependent color space to the calorimetric device-independent color space, and wherein the device model is constructed for use in the measurement-based color management system.

Abstract
Color measurements are generated from transform-based device profiles for use in a measurement-based color management system. The color measurements is generated by providing device-dependent color samples to a transform-based color management module and converting them to the profile connection space with the device'"'"'s transform-based profile. Color measurements are then generated from the transform-based color management module by applying an identity profile in place of a destination device profile. In addition, measurement data can be extracted directly from either the tone reproduction curve/matrix or n-dimensional lookup table transforms contained within a transform-based device profile.
