DETAILED DESCRIPTION

(6) Referring to FIGS. 1A and 1B, a secure placard 100, for example, a parking permit placard, includes a first side 102 and a second side 104. Each of the first side 102 and second side 104 includes a cut-out section 106 that facilitates hanging the secure placard from, for example, a rear-view mirror of a vehicle. In addition, the secure placard 100 includes a holographic portion 108a and 108b on the front side 102 and/or rear side 104, respectively. The holographic portions 108 include a pre-determined pattern embedded therein that make such holographic portions difficult to duplicate using conventional xerography or other duplication means. Further, refraction of light through such holographical portions 108 varies in accordance with the pre-determined pattern as the secure placard 100 is viewed from different angles. Thus, the authenticity of the holographic portion 108 (and, therefore, of the secure placard 100) can be visually confirmed.

(7) The secure placard 100 also includes one or more regions 110 in which additional information may be imprinted. In a preferred embodiment, such additional information is imprinted using xerography (e.g., using a laser printer) or another heat-based printing process. Such additional information may include the name of the person to whom the secure placard 100 is issued, a license plate number of the vehicle with which the secure placard 100 may be used, information regarding an authority that issued the secure placard 100, a month, day, and year when the secure placard 100 expires, and the like.

(8) FIG. 2 shows a printable substrate 200 that may be provided to an issuing authority to have information imprinted in the regions 110 thereof and to form the secure placard 100. Referring to FIGS. 2-4, the printable substrate comprises a base substrate 202 and a releasable adhesive layer 204 applied on top of the base substrate. A printable layer 206 is removably secured to the base substrate 202 by the releasable adhesive layer 204.

(9) In one embodiment, the base substrate 202 is a silicon-coated liner label and the printable layer 206 comprises a stiff laser printable material, including but not limited to a polyester film having a thickness of seven mils (i.e., 0.007 inches). The material for the releasable adhesive layer 204 is selected to adhere to the printable layer 206 when such layer is separated from the base substrate 202. In addition, the printable layer 206 may include a topcoat varnish that is toner receptive and applied to the printing surface thereof to enable laser (or other) printing thereon.

(10) The holographic portion 108 is formed by using, for example, a Cast and Cure™ process developed by Breit Technologies of Overland Park, Kans. In such process, a relatively thin layer of a varnish material is selectively applied to a top surface 207 of the printable layer 206. The varnish material may be applied in a band across the printable substrate 200, or across the entire surface of the printable substrate 200, or may be applied in areas of the printable substrate 200 corresponding to one or mare various shapes, such as the geographic outline of a state or region, or one or more patterns that may represent a shape, logo, or combination of such. While still wet, a holographic film is applied to the thin layer of varnish to emboss a pattern therein. Thereafter, the holographic film is removed, and the thin layer of varnish is cured (e.g., using ultraviolet light or other type of radiation). After curing, the thin layer of varnish (and the holographic pattern formed therein) is sufficiently durable to withstand high temperatures that may be encountered during fusing of a xerographic or other printing process. In some embodiments, such fusing temperature may be, for example, between about 175 degrees and about 215 degrees Celsius (about 347 degrees and 419 degrees Fahrenheit). However, in other embodiments, such fusing temperature may be less than 175 degrees Celsius or greater than 215 degrees Celsius. Further, such varnish material is not susceptible to a build-up of static charge that may cause mis-feed problems when the printable substrate 200 is transported past rollers of the printing device, and is sufficiently thin to eliminate potential stacking issues as well as jamming issues that may occur as the printable substrate 200 passes through the printing device.

(11) The printable substrate 200 includes a die cut 208 and a fold line 210. The die cut 208 and the fold line 210 may be formed in the printing substrate 200 either before the holographic portion 108 is applied thereto or after.

(12) After the printable substrate 200 has been formed as described above, the printable substrate 200 may be imprinted by a printing device to add the information in the areas 110. Thereafter, a portion 211 of the printable layer 206 defined by the die cut 208 and the releasable adhesive layer 204 secured thereto are separated from the base substrate 202 and folded along the fold line 210 to form the secure placard 100. The adhesive layer 204 on the portion 211 facilitates securing the first side 102 and the second side 104, respectively, to one another to form the secure placard 100. After folding and securing in this manner, the die-cut 208 forms edges 212 of the secure placard 100 and the fold line forms the edge 214 of the secure placard 100. Further, a first segment 216 and a second segment 218 of the die cut 208 align with one another to form the cut-out portion 106.

(13) Although the foregoing has been described as preparing a printable substrate 200 for use with a laser printing or xerographic printing process, it should be apparent the durability and static resistance may make printable substrate 200 suitable for any type of printing process including inkjet, lithography, intaglio, flexography, and the like to imprint information in the areas 110, especially those that are heat-based in which heat is applied during the imprinting process, for example, to melt, affix, fuse, cure or dry a material deposited on the substrate. Such printing substrate 200 may also be handwritten upon to imprint information in the areas 110.

(14) Although the holographic portion 108 is shown in FIGS. 1-4 as being substantially rectangular, it should be apparent that such holographic portion 108 may be non-rectangular. In one embodiment, the holographic portion 108 is formed as a string of characters that represent, for example, an expiration date.
