PRINTING RIBBON SECURITY APPARATUS AND METHOD |
摘要 |
<p>An apparatus and method of securing and maintaining the integrity of desired information on a ribbon and media subsequent to a printing operation is provided. The apparatus and method includes a thermal transfer printer having a print station and a printhead operable for performing a printing operation. The printhead is capable of performing an initial print operation and then being raised from the media, thereby allowing the used ribbon to be rewound a predetermined distance about a supply spindle. Thereafter, a second print operation is performed on the space previously printed upon using characters, designs or block-out patterns and the used ribbon is then wound onto a take-up spindle. In exemplary embodiments, the used ribbon can also be reprinted with a waste media several times thus further obscuring the image on the used ribbon.</p> |
