Abstract

A secure placard and a method of producing the secure placard are disclosed. A substrate includes a first portion and a second portion. The first portion of a substrate has varnish applied thereto and a holographic pattern is formed in the varnish. The substrate also includes a second portion that is free of the varnish. The second portion of the substrate is adapted to be printed on using a heat-based process without damage to the holographic pattern.

First claim

I/We claim:

1 . A secure placard, comprising:
a substrate; a first portion of the substrate having a varnish layer disposed thereon, wherein the varnish layer has a holographic pattern formed therein; and a second portion of the substrate free of the varnish; wherein the second portion is adapted to be printed on using a heat-based process without damage to the holographic pattern.

2 . The secure placard of claim 1 , further including a topcoat varnish applied to the substrate, wherein the topcoat varnish is toner receptive.

3 . The secure placard of claim 1 , wherein the substrate comprises a printable layer removably secured to a base substrate by an adhesive.

4 . The secure placard of claim 3 , wherein the printable layer comprises a stiff laser printable material.

5 . The secure placard of claim 4 , wherein the printable layer comprises a polyester film having a thickness of approximately 0.007 inches.

6 . The secure placard of claim 4 , wherein the printable includes a fold line and the substrate is folded along the fold line after second portion is printed on.

7 . The secure placard of claim 1 , further including a cut out portion that facilitates hanging the secure placard from a rear-view mirror of a vehicle.

8 . The secure placard of claim 1 , wherein the heat-based process includes xerography.

9 . The secure placard of claim 1 , wherein the secure placard is adapted to be exposed to a temperature of at least about 175° Celsius without damage thereto.

10 . A method of producing a secure placard, comprising the steps of:
applying varnish onto a first portion of a substrate; forming a holographic pattern in the varnish in the first portion; using a heat-based process to print in a second portion of the substrate without damaging the holographic pattern, wherein the second portion of the substrate is free of the varnish layer.

11 . The method of claim 10 , further including the step of applying a topcoat varnish to the substrate, wherein the topcoat varnish is toner receptive.

12 . The method of claim 10 , further including the step of forming the substrate by removably securing a printable layer to a base substrate using an adhesive.

13 . The method of claim 12 , wherein the printable layer comprises a stiff laser printable material.

14 . The method of claim 13 , wherein the printable layer comprises a polyester film having a thickness of approximately 0.007 inches.

15 . The method of claim 10 , wherein the step of forming the holographic pattern includes curing the varnish.

16 . The method of claim 10 , further including the step of folding the substrate along a fold line after the second portion is printing upon.

17 . The method of claim 10 , further including the step of hanging the secure placard from a rear-view mirror of a vehicle.

18 . The method of claim 10 , wherein the step of using a heat-based process includes the step of using a xerographic process.

19 . The method of claim 10 , wherein the step of using the heat-based processing includes exposing the secure placard to a temperature of at least 175° Celsius.
