Abstract: Systems, devices, and methods illuminate one or more areas on a calibration medium from a first side of the calibration medium with one or more respective light-emitting regions of a light source; detect light transmitted through the calibration medium at the one or more areas, thereby obtaining calibration-measurement information for at least one of the one or more light-emitting regions; illuminate one or more color patches on a color-measurement medium from a first side of the color-measurement medium with the one or more respective light-emitting regions of the light source; detect light transmitted through the one or more color patches printed on the color-measurement medium, thereby obtaining color-measurement information for at least one of the one or more light-emitting regions; and generate one or more transmissive measurements based on the calibration-measurement information and the color-measurement information.

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.

Abstract: Estimating the cost of ink in print jobs. The cost of ink in a print job is estimated based on printed area. After determining an ink coverage value for the print jobs and determining a cost of the ink, an ink cost factor is generated over time from the cost of the ink and from the total area ink coverage. The ink cost factor is used to estimate the cost of a print job based on area.

Abstract: Gamut maximizing black generation for printers. Generating device dependent data from device independent data uses both chromatic curves and achromatic curves, which are independently controllable and which each include a color space curve and a black curve. The achromatic and chromatic curves are generated using a set of input parameters. Once the curves are generated, the final color space values are generated using an interpolation between the achromatic curves and the chromatic curves.
