Abstract: Methods and apparatuses for generating fiducials via die cutting are provided. Laterally arranged die cutting members and fiducial-making members are provided onto a roller to respectively cut a first pattern and a fiducial mark on the same side of a web in a rotatory die cutting process. The fiducial mark is used to register a second pattern provided by a downstream station to the first pattern.

Abstract: A method for characterizing the uniformity of a material includes selecting a set of size scales at which to measure uniformity within an area of interest in an image of the material; suppressing features in the image smaller than a selected size scale of interest within the set of size scales; dividing the image into patches equal to the size scale of interest; and calculating a uniformity value within each patch.
