Photopolymeric Craft Stamp Indexing Images and Method of Making

摘要

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.

主权项

1. A craft stamp indexing image, comprising:
an actinic radiation-transmitting substrate; and ink applied to the substrate;
the ink being that does not transmit visible wavelengths of light and does transmit radiation that cures photopolymers.
