  • Tone reproduction curve error reduction
    Patent number: 9014578
    Abstract: Control parameters of a printing device are optimized using a process model to reduce a process tone reproduction curve (TRC) error between a process TRC and a desired TRC. Tone-corrected halftone levels for the printing device are generated using a sensor model to reduce a printing device TRC error between a TRC of the printing device and the desired TRC, based on color patches printed by the printing device using the control parameters as have been optimized, as measured by one or more sensors of the printing device.
    Type: Grant
