Generating calibrated LUT providing NPac response utilizing calibration element for HANS LUT describing drop weight deviation based on measurement data
A system includes a memory to store at least one Halftone Area Neugebauer Separation (HANS) look-up table (LUT) that represents a predetermined drop weight for N colorant channels of a printer. The HANS LUT provides a given Neugebauer Primary area coverage in response to a device color input value. Measurement data stored in the memory represents measured drop weight values for the N colorant channels of the printer. A processor executes instructions stored in the memory. The instructions are to compute a calibration element for the HANS LUT that describes a drop-weight deviation with respect to the HANS LUT based on the measured drop weight values. The instructions are to apply the calibration element to at least a portion of the HANS LUT to generate a calibrated LUT.
