  • Patent number: 5314560
    Abstract: A blinded sheet or label is produced from a base sheet suitable for use in blinded testing or other applications where secret information appears. The base sheet is formed from a carrier web having a release surface joined by adhesive to face stock paper preprinted with desired blocks of information. The base sheet is advanced through a hot stamp machine, where a roll of scratch-off, transferable opaque laminate is mounted for simultaneous advancement through the hot stamp machine. The hot stamp machine is programmed to apply heat and pressure through a reciprocating platen containing a transfer die to the opaque laminate roll and base sheet at a selected location along the base sheet, causing the opaque laminate to transfer to the base sheet over the secret block of information. The reciprocating platen then moves away from the base sheet so that it and the opaque laminate roll can advance for the process to repeat itself over another secret block of information.
