Sheet explosives are a poor excuse to examine paper (including photo paper) content for images and/or copy (writing/type). ETD swabbing is a less intrusive means that can be used to rule out a variety of explosives without the TSA hiding behind a claim about "sheet explosives" concern resulting in TSA examination of paper content for images and/or writing/type.
