Determination of control points for construction of first color space-to-second color space look-up table

摘要

Determining the control points for constructing a lookup table from a first color space to a second color space is disclosed. Black and white control points are determined based on an allowable total colorant amount and an absence of colorant, respectively. Control points between the black control point and the white control point are determined. A primary control point is determined for each of a number of first and secondary primary colors, based at least on the allowable total colorant amount. Control points between the white control point and the primary control point for each primary color are also determined. Control points between the black control point and the primary control point for each primary color are finally determined.
