Abstract
A tamper-resisting negotiable instrument, its method of manufacture and use are disclosed. The instrument includes a stack of webs comprising a first web having a lower surface adapted to receive images; a second, removable web, having an image transferring layer on its upper surface in contact with the image receiving surface of the first web and an image receiving layer on its lower surface; and a third removable web including an image transferring layer on its upper surface facing the second web. The image transferring layers comprise selected areas of the web upper surfaces which provide data zones in which specific information is desired to appear. Inscription of an image against the upper surface of the top web in the stack transfers the image from the image transferring layers of the webs therebelow to the lower surfaces of the webs thereabove leaving negative images in the data zones of the image transferring layers. Visual inspection of the negative images shows those images have been altered if there has been tampering.
