Inventors:

David L. Hebert - Suncook NH

Assignee:

Moore Business Forms, Inc. - Grand Island NY

International Classification:

B42D 1500

US Classification:

283 81

Abstract:

An identification card intermediate includes a transparent plastic substrate with a base stock and release liner each covering about half of the substrate. Indicia is printed on a first face of the base stock. A sticker, having indicia printed on a first face of it, is connected by repositional adhesive to the release liner. The release liner and base stock are connected by permanent adhesive to the plastic substrate. A number of stickers may be provided on the release liner, each including a phone number (e. g. different phone numbers), or providing basically the same information in different languages. An identification card is produced by removing the sticker from the release liner and placing it on the base stock, then removing the release liner from the substrate, and moving the substrate over the first face of the base stock. The intermediate of the identification card is produced by moving a web comprising the substrate with attachments, printing indicia on the stickers, and blowing at least one sticker on the release liner of each intermediate as the web is moving.
