A handprinted signature partially written on top of some dried typewriter correction fluid was examined with infrared irradiation on the VSC-1. The ink on top of the correction fluid appeared to continue to be absorbed while the portion of the ink written on the paper became transparent. This apparent differentiation was initially misinterpreted as a phenomenon similar to the Sansi/Cantu observation that under certain conditions the infrared luminosity of the ink line can be different. A complete examination of the entire document lead to the correct interpretation and resolution of this apparent contradiction.
