Publication number: 20090309954Abstract: Two or more sets of non-contiguous features are selected from a pattern of non-contiguous features, and each set is imaged separately during a single scan of a multi-channel imaging head. The non-contiguous features selected in each set can be selected such that they are imaged with substantially the same transferred characteristics.
