Abstract
Line width of images marked by an image marking device is adjusted by reading a calibration patch marked by the marking device, and then adjusting one or more settings of the marking device, such as exposure intensity or cleaning field intensity, independent of the digital control of the tone reproduction curve so that the line width of subsequently marked images becomes closer to a target value. A digital control may be implemented to compensate for the impact of the modification of the one or more settings on the tone reproduction curve.
