Definitions

  • the axis in color space may be L* in CIELAB space.
  • Fig. 5 The above discussion with respect to Fig. 5 is related to a forward LUT.
  • the inverse LUT it is advantageous to include one or more, and preferably all ink changing points as sampling points. Using such an inverse LUT results in smaller errors and better color reproduction.
