- the term "informational article” refers to an article which is adapted to provide through words, graphics, color codes or other means information which may be provided in a form visually perceived by the human eye or in machine readable form such as information stored on magnetic media, such as a magnetic strip or microchip.
- the term will expressly include, but not be limited to, identification cards, credit cards, debit cards, smart cards, organization membership cards, security system cards, security entry permits, and other information providing articles wherein it may be desired to resist alteration, tampering or reproduction.
- hologram is used in its conventional broad sense and includes the use of a single hologram element alone or multiple hologram elements which may or may not be touching each other or physically in close proximity to each other.
- the term "metal strip” will include a strip made of metal, as well as other materials which have been partially or totally covered by a metal layer. Referring in greater detail to Figures 1 and 2, there is shown a form of informational article 2.
- the card has a first line of general information 6 which identifies the source of the card as "ABC BANK" and will appear on all cards.
- variable information which will appear on every item in the series. Positioned below the fixed information are lines of variable data 8, 10 which is customized to the particular holder of the card. In this example, the card bears number 1234- 5678 and the individual is identified as "D.E. SMITH.” It is important that the information 6, 8, 10 be protected against (a) alteration by resisting access to the information 6, 8, 10 and (b) photocopying.
- a metal foil layer 12 has a hologram indicated generally by the referenced number 60 formed directly in the foil 12 through embossment. This embossed foil 12, therefore, provides both the desired requirement of physical relief and metallizing within the single article.
- the foil 12 may be aluminum foil or copper foil, for example, and may have a thickness of about 15 to 150 microns.
- the card 2 may have a total thickness of about 750 microns, for example.
- the fixed information will also include the multi-component graphic element 18 which may be of any desired size and shape and may be repeated at two or more locations, if desired.
- the hologram in the form shown, consists of a plurality of generally diamond- shaped elements with a first group 22, 24, 26, 28, 30, 32, 34, 36, 38 being of a larger size than the smaller diamonds 42, 44, 46, 48, 50, 52, 54 and 58.
- the diamonds are positioned across the informational article 2 and are generally grouped into vertical arrays of two or three diamonds. It will be noted that portions of the information 6, 8, 10 overlie the holograms. In this manner, any effort to counterfeit as by photocopying and subsequently alter the photocopy will be resisted as the hologram will interfere with such copying and alteration.
- portions of the informational article will be of a substantially different color than other portions. Such portions are preferably provided in positions generally overlying the hologram and underlying the information.
- a plurality of generally vertically oriented, generally parallel lines 60, 64, 68, 70, 72, 74 and a pair of generally parallel end portions 80, 84 have a color which contrasts substantially with the remaining background color indicated generally by the reference number 90 of the remainder of the card.
- color band 60 overlies hologram 54 and underlies the letter "A" in the fixed information.
- Color band 64 underlies a portion of the letter "C", a portion of the number "3" and a portion of letter "E".
- Color band 68 underlies a portion of the second letter “A” in the fixed information 6 and color band 70 underlies a portion of the number “7” and the letter “T” while overlying hologram segment 58.
- the number “8” overlies hologram 26.
- a resinous plastic material 100 encapsulates the hologram containing metal foil 12, fixed information 6, and variable information 8, 10, as well as the color bands 60, 64, 68, 70, 72, 74. It is preferred that the thickness "T" of the resinous plastic material portion overlying the foil 12 and hologram, be about 10 to 20 mils.
- an overlying anti-abrasive coating 104 may be secured to the resinous plastic material 100 preferably, while the resinous plastic material is at an elevated temperature so as to take advantage of the heat contained therein.
- the resinous plastic material may, for example, be polyethylene.
- the resinous plastic material is preferably thermoplastic as any melting of the same will tend to damage or destroy the information 6, 8, 10.
- the resinous plastic material 100 and the anti-abrasive coating 104, if used, should be transparent so as to permit ready visual observation of the information 6, 8, 10.
- Figure 3 shows a schematic illustration of a method of making the informational article of Figures 1 and 2.
- a coil 126 of metal foil such as aluminum foil, may be either single width or multiple width, depending upon the informational article being made. There may be not only severance of longitudinal segments to create individual informational articles, but also creating a plurality across the width of the strip requiring additional slitting to separate the individual informational articles.
- Cooperating rolls 128, 170 serve to emboss the foil 122 as it passes therebetween to create a hologram in the foil.
- the foil moving in the direction indicated by the arrows A, B, C is then subjected to a printing operation wherein the cooperating printing means 132, 134 causes "information" to be provided on upper surface 140 of the foil 122 overlying the hologram.
- the foil then enters extruder 144 wherein the foil 122 containing on its upwardly facing surface the hologram and overlying information is encapsulated with a resinous plastic material 146 to create the construction shown generally in Figure 2. If it is desired to have an overlying anti-abrasion layer 104, this may be applied as either a coating or a film after extrusion, but preferably during the period of time that the resinous plastic material 146 is at an elevated temperature.
- a suitable reel (not shown), may serve as the source of the film and a pair of rolls (not shown) applying pressure cause layer 104 to be urged into intimate contact with the upper surface of the resinous plastic material 146.
- a cutter which may consist of an anvil base 150 and a cutting element 152, which is well known to those skilled in the art, severs the longitudinal product into a plurality of individual informational articles, such as 153, 154, which are transported by endless belt conveyor 160 to the desired cooling, packaging or storage area.
- a bar code (not shown) may be provided in protected position within resinous plastic material 100 overlying hologram, but not interfering with information 6, 8, 10.
- Figures 1 and 2 isolates the information 6, 8, 10 from direct access and alteration. Also, the presence of the hologram, the bands of material of different color and the positioning of the information with respect to both will resist photocopying and alteration of the photocopy in efforts to counterfeit the same. This is accomplished in a streamlined manner with a minimum number of material layers.
- the informational article is created from a lens 190 and a base 192.
- the lens has a resinous plastic film 194 which may be composed of a polyester or polypropylene, for example, and may have an overlying transparent anti-abrasive coating 196. It is preferred that the film 194 have a thickness of about 10 to 25 percent of the overall card thickness.
- An embossed hologram 200 is formed in the underside of the lens 190 and information 202 is provided adjacent to the hologram 200 which is subsequently metallized 203 as by coating or foil.
- the lens 190 will permit viewing from above with the hologram 200 partially overlying the information 202, which may preferably be created by extrusion.
- Base 192 has a metal core 206 encapsulated within a resinous plastic material 210.
