Abstract
A method of protecting an informational article, on which variable information is inserted, from photocopy duplication and alteration. The method comprises providing an informational article substrate having a zone for inserting the variable information and a refractive image disposed within the zone. The variable information is inserted in the zone, and transparent tape is secured over the variable information. The transparent tape has a write-resistant exposed surface. The refractive image will resist photocopy duplication of the variable information article, and the write-resistant exposed surface will resist alteration of the inserted variable information.
