Patent ID: 8665487

Claim:
A method for calibration of at least one half-tone density in a printer, comprising the steps of: performing, by a controller of the printer, a plurality of calibration cycles for a predefined half-tone density over a period of time; acquiring :by the controller of the printer, a plurality of half-tone density values each from a respective one of a plurality of test patches each generated on a belt in the printer during a respective one of the plurality of calibration cycles over the period of time, each of the plurality of test patches embodying the predefined half-tone density; generating, by the controller of the printer, a mathematically smoothed half-tone density value from the plurality of half-tone density values acquired from the plurality of test patches during the performance of the plurality of calibration cycles for the predefined half-tone density over the period of time; and calibrating, by the controller of the printer, a half-tone density in the printer based upon the mathematically smoothed half-tone density value.
