Abstract:
1. A method for forming an image of a pattern of features on media with radiation beams emitted by an imaging head while scanning over the media along a scan direction, wherein the features in the pattern are regularly arranged along a first direction and along a second direction that intersects the first direction, and the pattern includes a feature with a first edge portion that extends along a direction that is skewed by a skew angle relative to the scan direction, the method comprising: determining a pitch of the features along the first direction; determining a first size of a first pixel to be formed on the media based at least on the pitch of the features along the first direction, wherein the first size is along a direction that intersects the scan direction; determining a pitch of the features along the second direction; determining a second size of a second pixel to be formed on the media based at least on the pitch of the features along the second direction; wherein the second size is along the scan direction; determining an offset along the scan direction between a second scan-line of pixels to be formed on the media and a first scan-line of pixels to be formed on the media, the offset being determined based at least on the skew angle and the first size; controlling the imaging head to emit the radiation beams to form the image on the media while scanning along the scan direction; controlling the imaging head to form the first pixel comprising the determined first size and the second pixel comprising the determined second size while scanning over the media; and controlling the imaging head to form the first scan-line of pixels and the second scan-line of pixels while scanning over the media, wherein the second scan-line is offset from the first scan-line by the determined offset.
