Ongoing Auction: T206 Printer Scrap?

A rubber stamp generally has a bold dark rim around the graphics that typically is visible to the naked eye or light magnification. When you press the inked stamp surface to the paper the ink is pushed to the edges creating the rim of heavier ink. A different type of process, lithography generally doesn't have such a rim. T206 lithography has a microscopic rim due to the ink used, but this rim is visible only under the microscope not the naked eye or around the house magnifying glass. Printing details will be harder to identify the rougher the surface, with the back of T206 being fairly rough. You can only see the microscopic lithographic rim on the smooth front of the card, not the back. Though I would suspect that most rubber stamps would be obvious even on back, as the rubber stamp rim tends bold and very noticeable.
