The present invention relates generally to advertising inserts, and more particularly to an insert comprising a promotional item such as a coupon or advertisement located inside a paper roller used to carry paper products and the like. The sheet stack is inserted into the binder in such a way that the stack’s end face comes into contact with the adhesive strip. The medium chain fatty acids include, for example, caproic acid, caprylic acid, capric acid, lauric acid, or combinations thereof. One or more post-inspection tasks can be performed, including, but not limited to, merging inspection runs, removing duplicate defects, removing straight-line false alarms, and characterizing defects.
