发明名称 Greyscale calibration method in digital printing
摘要 The method of the invention allows adjustment of the Greyscale of a digital print in addition to adjusting the individual colors thereof, which have a tendency to vary as the respective inks are changed, the paper or canvas stocked utilized is replaced, or the printer drifts with time. In accordance with a preferred embodiment of the method, the densitometers employed in calibrating the printer are individually adjustable to vary the Greyscale, where needed, while continuing to tailor the component colors displayed. Rather than utilizing prior art methods of only calibrating the printer, the method of the invention additionally permits the adjustment of the calibrator in maintaining proper Greyscale.
