<p>A high-definition printing process, particularly for security strips for currency bills and the like, comprising the steps of: preparing a substrate in tape form; continuously depositing a layer of light-sensitive lacquer on the substrate; applying a masking element to the layer of light-sensitive lacquer, the masking element being transparent at areas in which the lacquer is meant to change state by continuous exposure to ultraviolet rays; and removing portions of lacquer that have not changed state from areas of the substrate that correspond to non-transparent portions of the masking element, the portions of lacquer that have changed state constituting a protective barrier for subsequent processes for forming high-definition miniaturized characters.</p> |
