  • Patent number: 7982873
    Abstract: A method and system are provided to correct differences among multiple spectrophotometers. In one form, one spectrophotometer of a plurality that may be present in an image rendering system is treated as “primary”. Additional spectrophotometers are treated as “secondary”. The spectrum of a color from a secondary spectrophotometer is transformed by a linear transformation to an adjusted spectrum, which then is converted to L*a*b* (if desired) using standard techniques. The L*a*b* thus produced is, on average, substantially closer to the L*a*b* that the primary spectrophotometer would have produced when measuring the same color than it is to the L*a*b* that the secondary spectrophotometer would have produced without any correction. The linear transformation is generated by linear regression to minimize the spectral error, followed by non-linear optimization to minimize the error relative to a color difference metric—such as DeltaE 2000.

  • Publication number: 20110169216
    Abstract: A method and system for performing sheet registration are disclosed. Output values for a sheet may be identified within a reference frame. A difference between each output value and a corresponding desired output value may be determined. Input values may be determined based on at least the differences. State feedback values may be determined based on information received from one or more sensors. Jerk values may be determined for multiple drive rolls based on the input values and the state feedback values. A desired angular velocity for each drive roll may be determined based on the corresponding jerk value. A motor voltage may be determined for each drive roll that tracks an observed angular velocity value to the desired angular velocity value. The jerk values may create a linear differential relationship between the input values and the output values. The steps may be performed multiple times.
