  • Crosstalk correction
    Patent number: 6156465
    Abstract: A method of crosstalk correction comprises producing a calibration image having different printed image densities in grayscale, measuring the printed image densities at the different light exposure values to obtain a correlation of printed density in grayscale as a function of light exposure value over a range of light exposure values, obtaining experimental analytical density values for a selected light exposure value within the range of light exposure values and using the correlation of printed density as a function of light exposure value and the experimental analytical density values to correct for crosstalk.
