Abstract
Systems and methods for establishing ink usage of process channels are provided. Separation curves are generated that determine how multiple ink channels are used to render a corresponding process channel of an image. The separation curves are generated using process values and density measurements or estimations. A PVR curve is established to identify target densities. When a combination of ink channels are used, the model is accessed based on one of the ink channels to determine a contribution of the other ink channel to achieve the target density. Each ink channel has a corresponding curve and all of the curves collectively provide a smooth and predictable progression from zero coverage to full coverage for the ink channels.
