Patent Number Title Of Patent Date Issued
6461544 Two-dimensional/three-dimensional graphic material and method of making same October 8, 2002
Graphic material includes at least one area bearing a hologram and at least one area bearing a diffraction grating. Preferably, the diffraction grating and the hologram are simultaneously viewable from at least one perspective. The graphic material is made using an embossing die grown
6194031 Method for making high refractive index (HRI) film by adjusting the flow rate of a vaporized mat February 27, 2001
This invention includes a method for heating a deposition material to form a vapor that may be deposited on a polymer film and thereby create a holographic film or similar material. Included within this method is a vaporizer that has an adjustable aperture. The vaporizer may have (i) a
5956164 Two-dimensional/three dimensional graphic material and method of making same September 21, 1999
Graphic material includes at least one area bearing a hologram and at least one area bearing a diffraction grating. Preferably, the diffraction grating and the hologram are simultaneously viewable from at least one perspective. The graphic material is made using an embossing die grown
5951769 Method and apparatus for making high refractive index (HRI) film September 14, 1999
This invention includes an apparatus for heating a deposition material to form a vapor that may be deposited on a polymer film and thereby create a holographic film or similar material. A system and a method for producing such a film is also provided. Included within this system is a vap
5834096 Hologram with integral printed indicia November 10, 1998
A material with holographic and non-holographic displayable indicia thereupon has an embossed holographic microtexture upon a surface thereof for forming a reflection hologram and resulting in an associated visible holographic pattern. A non-holographic pattern is printed with a printing
5695808 Method for making transparent reflective films December 9, 1997
A method for making transparent, reflective films includes coating a polymer film with ZnS by charging a set of carbon crucibles with ZnS cubes or pellets. The crucibles are heated by induction in a vacuum deposition chamber having a supply roll of the polymer film and a take-up roll. Th
5603259 In-line cold foil transfer process and apparatus February 18, 1997
An improved apparatus and method employ a printing press which normally includes a plurality of printing stations and a plurality of heating stations. An adhesive, rather than ink, is applied to a continuous web at at least one of the printing stations and heat is subsequently applied to
5585144 Hologram with integral printed indicia December 17, 1996
A material with holographic and non-holographic displayable indicia thereupon has an embossed holographic microtexture upon a surface thereof for forming a reflection hologram and resulting in an associated visible holographic pattern. A non-holographic pattern is primed with a priming
5513019 Semi-transparent reflective layer for a phase hologram April 30, 1996
A phase hologram is embossed in a mylar web having a reflective layer which is made from tin tungsten oxide, zinc sulfide, or a mixture thereof. The embossed microtexture produces a hologram that is semi-transparent, thereby allowing the visualization of indicia underlying the hologram.
5351142 Semi-transparent reflective layer for a phase hologram September 27, 1994
A phase hologram is embossed in a mylar web having a tin tungsten oxide reflective layer deposited upon. The embossed microtexture produces a hologram that is semi-transparent, thereby allowing the visualization of indicia underlying the hologram.
5331443 Laser engraved verification hologram and associated methods July 19, 1994
A method for increasing the authentication effect of a verification hologram to be affixed to a protected document includes laser etching individualized indicia into the reflective layer of each hologram produced en masse on a moving, continuous web. The laser is finely focused and g
5158845 Multi-colored material using rainbow grating October 27, 1992
A decorative multi-colored material and method of making same using rainbow gratings simultaneously evidence different color patterns which change through the color spectrum. The patterns are formed from separate impressions from different portions of a common rainbow grating to provide
5073221 Apparatus and process of making magnetically readable cards December 17, 1991
Magnetic stripes are applied to magnetically readable credit cards by incorporating the magnetic stripes in a cover sheet and laminating this cover sheet to a core stock sheet and then severing the laminated assembly into individual cards. The magnetic material bearing cover sheet is mad
