Patent ID: 8358441

Claim:
A method for modeling a colorant-limited, multi-dimensional colorant space, said method comprising: a) representing a full-colorant space as a multi-dimensional full-colorant hyper cube without colorant limitations; b) sampling said full-colorant color space using a rectilinear sampling scheme, thereby producing rectilinear sample points; c) representing a colorant-limited colorant space with a multi-dimensional hyper cube limited by a colorant-limitation hyperplane; d) transforming said rectilinear sample points, using a bijective mapping process, to said colorant-limited colorant space, thereby producing transformed rectilinear sample points; e) tessellating said rectilinear sample points into full-colorant-color space simplexes; f) obtaining intersection sample points located at the intersection of the edges of said full-colorant-color-space simplexes and the intersection lines between the colorant limitation hyper-plane and said full colorant hypercube; and g) using said transformed rectilinear sample points and said intersection sample points to model a device color gamut of the colorant-limited colorant space, by generating color patches on an output device and measuring said color patches with a measuring device.
