| Zusammenfassung: | The method involves using a threshold matrix in which the thresholds represent one or several screen points of a screen arranged with an angel. The desired screen width and the desired angel are approximated with the screen. A nonconformance between the desired screen and the screen approximated by the threshold matrix is determined during the read out of the thresholds. The nonconformance is compensated by a correction of the read out address for the threshold matrix as soon as the nonconformance exceeds a predetermined threshold. |
