Method for efficient calibration of printing devices |
摘要 |
A method for characterizing a printing device response for a halftone screen includes (a) generating a plurality of test patches, each test patch comprising a dot pattern having less than three different base patterns for the halftone screen; (b) measuring the luminance of selected ones of the test patches; (c) plotting the luminance measurements to provide a set of calibrated points on a printer calibration curve; and (d) generating the printer calibration curve between adjacent calibrated points using an equation establishing a relationship between ink area coverage and reflectance of the image.
