ABSTRACT:
A method for deriving a reverse model look-up table whose entries represent device dependent colors as a function of device independent colors, based on a forward model look-up table whose entries represent device independent colors obtained in response to printout of corresponding device dependent colors. For each device independent target color, a binary search of the forward model look-up table is performed so as to locate a cell that contains the device independent target color. The grid points from the forward model look-up table that define the cell are interpolated so as to obtain device dependent colors corresponding to the device independent target color. The device dependent color is stored at the grid point for the reverse model look-up table at a position corresponding to the device independent target color.
