Abstract
Methods are provided to image patterns on a media. A pitch of a repeating pattern of sub-regions is determined and an imaging head is operated which has an array of individually addressable channels to direct imaging beams to form an image swath on the media. The individually addressable channels are controlled to image the repeating pattern of features and the pitch of the repeating pattern of features is adjusted to equal substantially the pitch of the repeating patterns of sub-regions.

A method for imaging with pixels a repeating pattern of features in aligned relationship to a registration region comprising a repeating pattern of sub-regions, the method comprising:
- determining a pitch of the repeating pattern of sub-regions;
- adjusting a size of the pixels;
- operating an imaging head comprising an array of individually addressable channels to direct imaging beams to form an image swath on a media, each of the imaging beams being operable for imaging the pixels on the media;
- while forming the image swath on the media, controlling the individually addressable channels to image the repeating pattern of features;
- adjusting a pitch of the repeating pattern of features to equal substantially the pitch of the repeating pattern of sub-regions in a direction generally perpendicular to the image swath;
- and
- wherein adjusting the pitch of the repeating pattern of features to equal substantially the pitch of the repeating patterns of sub-regions comprises rotating the array of individually addressable channels with respect to the repeating pattern of sub-regions.
