TROY Group Laser Indelible Solution White Paper Datasheet

OVERVIEW

TROY Group, Inc. has developed a new digital printing technology for security
printing (patents awarded worldwide, contact TROY for further information). This
new technology is the TROY Laser Indelible Solution. The TROY Laser
Indelible Solution consists of TROY Security Toner and laser bond paper coated
with the TROY Laser Indelible Coating. This toner and paper system works
together to create an indelible image on documents that are printed on laser
printers.

HOW IT WORKS

Laser Indelible paper has a special coating in area(s) of each sheet where the
desired security feature is located. During the coating drying process a
“migration agent” in the coating is absorbed into the paper fibers. This migration
agent is designed to interact with TROY Security Toner (Figures 1 & 2). The
TROY Security Toner is a specialty toner formulation containing a special dye
(Figure 3). When printed, the dye in the toner is released by the migration agent
and drawn through the paper (Figure 4). The resulting image is a black toner
character or graphic on the front of a document and the same character or
graphic in red dye, permeating the thickness of the paper. The red image is also
visible as a mirror image of the backside of the document.
