1. A method for imaging a feature by laser-induced thermal transfer, the method comprising: on a substrate comprising a donor element and a receiver element, scanning a plurality of independently-controllable light beams in a scan direction along corresponding scan lines, each light beam operable for forming a corresponding image pixel on the receiver element; imaging a feature by operating a contiguous group of the beams to transfer an image-forming material from the donor element to the receiver element; and, while imaging the feature, controlling intensities of a first edge sub-group of one or more of the beams corresponding to a first portion of the feature extending along a first edge of the feature and a second edge sub-group of one or more of the beams corresponding to a second portion of the feature extending along a second edge of the feature to have intensities different from intensities of an interior sub-group of one or more of the beams corresponding to an interior portion of the feature.
