Identification document with lenticular watermark

摘要

An identification document and method of making such a document includes a transparent window which incorporates micro printing and lenticular technology to record document bearer specific information on a microscopic and macroscopic level. A window is punched into an opaque layer, respective laser engravable synthetic transparent layers are laminated to opposing sides of the opaque layer, and respective protective synthetic transparent layers are laminated to the outer sides of the two laser engravable synthetic transparent layers. A lenticular array is then formed on the front of the window in the associated protective synthetic transparent layer and then document bearer specific information is micro printed using a laser inscribing into the rear of the window in the laser engravable synthetic transparent layers. The phase shifted image is comprised of alphanumeric characters which are readable with the aid of a magnifying device, but which are also arranged to form a macroscopic lenticular image viewable through the lenticular array.
