Field notes
The described sequence starts with brief UVA exposure to reduce the dye to a colorless state; after cutting, oxygen reaches the exposed adhesive edge and the indicator regains color. The page includes an oxidation simulator with five named dyes and links to the patent, published application, and USPTO Patent Center record. Its cost model uses Pitney Bowes' parcel volume while leaving search rate, seconds, and labor cost adjustable.
