Patent abstract
An indexing image for craft stamps that is opaque to the eye but transparent to UV light is produced by printing a wavelength-specific solvent-based ink on the stamp substrate. This eliminates the step of printing a separate adhesive-backed indexing image sheet and applying it to the substrate.
