Abstract
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.
