Abstract
Systems and methods for dynamically limiting total colorant coverage in multi-colorant rendering. Two polyhedra are defined: one contains all the colors that exceed the total colorant limit, and another is within the colorant limit that contains the results of the colorant limitation process. Data is received to identify a specified contone color, which is processed to decide whether it is inside one of the polyhedra. If the specified contone color is not within either polyhedra, the specified contone color is used in the rendering process. Alternatively, if the specified contone color is within one of the polyhedra, the value representing the specified contone color is compressed into the second polyhedra volume to obtain a resultant contone color that is used in the rendering process.
