摘要： A method of accurately printing a target color is provided. The method comprises: in a first step measuring the light spectrum (106) of a first printed color sample (104), which has been printed with a first ink coverage; and from the measured light spectrum calculating a color discrepancy between the first printed color sample and the target color. The method further comprises in a second step calculating an improved ink coverage (112), and printing a second color sample with the improved ink coverage (104). The aforementioned steps are repeated until a predetermined condition for accuracy of the target color has been reached (110).

摘要： A method of enabling preparing a printing system calibrated with a first halftone screen for printing with a second halftone screen. The calibration is represented by calibration data. Calibration data for the second halftone screen is produced from the existing calibration data of the first halftone screen without resorting to previous calibration data for the second halftone screen, based on correlation data which represent a first-order correlation between the halftone screens.
