Abstract
A method for identifying pixels corresponding to an imprint field edge. Generating a set of pixel patterns, each pixel pattern from the set of pixel patterns including edge pixels predicted to be near the imprint field edge of a test imprint field and central pixels corresponding to a center portion of the test imprint field, wherein the edge pixels are turned on, each pixel pattern from the set of pixel patterns having different edge pixels selected and imprinting the test imprint field with a spatially modulated light source that is modulated with at least one pixel pattern from the set of pixel patterns.
