Algorithm-Independent Color Calibration for Digital Halftoning

A novel method based on measuring 2 × pixel patterns provides halftone-algorithm independent color calib tion for digital halftoning. The binary CMY(K) colo signals can be mapped into CIE XYZ color space at printer resolution level. Therefore, any binary CMY( color images can be described as continuous-tone ages in standard color spaces. The new method has successfully applied to halftone screen calibration, v tor error diffusions, as well as stochastic screens.
