    Abstract: A direct device-space-to-device-space transform adjusts the amount of actual black ink, to avoid highlight and midtone granularity in incremental printing—but with no need for translation into perceptual space. If the amount of black ink specified in the input data for a particular color is very small or very large, then that specified color is passed through the transform without substantial change. Thereby the amount of actual black ink and other colorants is held as nearly as practical at levels dictated by device-space input specifications while minimizing visible granularity. Replacement behavior is chosen to smoothly blend between different kinds of operation in different tonal ranges. This system accommodates personnel trained in classical printing-press technologies, who are accustomed to full control over amounts of black and other colorants.

    Abstract: A number of sets of color values for an imaging system to output a corresponding number of neutral gray outputs at different lightness levels, is computed by interpolation, based at least in part on received or taken measurements of a number of near-neutral patches for the different lightness levels printed by the imaging system using a number of sets of color values of the imaging system's color space. The color values of the imaging system's color space are derived based on a number of sets of color values of a profile connection space (PCS) in accordance with a print table of a color profile of the imaging system mapping color value sets from the PCS to color value sets in the imaging system's color space. The various sets of defining color values define the near-neutral patches in the PCS.
