Abstract
Abstract Disclosed is a method of manufacturing multilayer identity cards by electrophotographically reproducing identity information on a card core material and then laminating protective film on both sides of the core material. In preferred embodiments, the core material itself may be made up of several layers with additional security markings thereon. A relief grid image or a hologram can be inserted into the card core prior to lamination. In a further embodiment, after lamination, the identity card blank is photomechanically scanned and positioned in accordance with existing control marks and punched to produce the finished identity card.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
153 words
A process for the manufacture of multilayer identify cards, said process comprising the steps of: providing a core material magazine; providing a card core material in said magazine; automatically removing said card core material from the magazine; feeding said core material into an electrophotographic copying device; directly transferring identity information from a recording carrier in said copying machine to said card core material forming an image carrier; transporting said card core materials to an intermediate magazine and serially storing them therein; subsequent to said transporting step, moving said card core materials into a laminating press; supplying said laminating press with transparent protective films; inserting a relief grid image into the card core as a security marking, said relief grid image having a linear grid structure, the grid depth thereof determining a given image color upon reproduction; and laminating said protective films on each side of said card core material forming identity card blanks.
Claim 2
Dependent Claim
153 words
A process for the manufacture of multilayer identify cards, said process comprising the steps of: providing a core material magazine; providing a card core material in said magazine; automatically removing said card core material from the magazine; feeding said core material into an electrophotographic copying device; directly transferring identity information from a recording carrier in said copying machine to said card core material forming an image carrier; transporting said card core materials to an intermediate magazine and serially storing them therein; subsequent to said transporting step, moving said card core materials into a laminating press; supplying said laminating press with transparent protective films; inserting a relief grid image into the card core as a security marking, said relief grid image having a linear grid structure, the grid depth thereof determining a given image color upon reproduction; and laminating said protective films on each side of said card core material forming identity card blanks.
Claim 3
Dependent Claim
114 words
A process for the manufacture of a plurality of multilayer identity cards, said process comprising: providing originals, each with identity information comprising at least one photograph and a data block; electrophotographically reproducing each of said identity informations on a recording carrier; developing and transferring each of said identity information to a card core material; serially storing said card core materials in an intermediate magazine; inserting a relief grid image into the card core as a security marking, said relief grid image having a linear grid structure, the grid depth thereof determining a given image color upon reproduction; and laminating transparent protective films on each side of said card core materials forming identity card blanks.
Claim 4
Dependent Claim
114 words
A process for the manufacture of a plurality of multilayer identity cards, said process comprising: providing originals, each with identity information comprising at least one photograph and a data block; electrophotographically reproducing each of said identity informations on a recording carrier; developing and transferring each of said identity information to a card core material; serially storing said card core materials in an intermediate magazine; inserting a relief grid image into the card core as a security marking, said relief grid image having a linear grid structure, the grid depth thereof determining a given image color upon reproduction; and laminating transparent protective films on each side of said card core materials forming identity card blanks.
Claim 5
Dependent Claim
68 words
A process according to claim 1, wherein said identity information comprises at least one photograph and a data block and said transferring step comprises the steps of: providing an original with said identity information; electrophotographically reproducing said identity information as an image on a recording carrier; developing said image on said recording carrier; and transferring said identity information image from said recording carrier to said card core material.
Claim 6
Dependent Claim
45 words
A process according to claim 1 or 2, further comprising the steps of: photomechanically scanning said card blanks after said laminating step; adjusting the position of said card blanks according to existing control marks; and punching said card blanks to form the final identity cards.
Claim 7
Dependent Claim
31 words
A process according to claim 1 or 2, wherein said card core material comprises film material having a matt coloring, which film material is dyed white by the addition of pigments.
Claim 8
Dependent Claim
25 words
A process according to claim 5, wherein said film material and said transparent protective films are comprised of a fusible polymer based on polyvinyl chloride.
Claim 9
Dependent Claim
24 words
A process according to claim 6, further comprising the step of providing, prior to said reproducing step, security markings on said card core material.
Claim 10
Dependent Claim
18 words
A process according to claim 6, wherein said image on said recording carrier is a white/gray/black toner image.
Claim 11
Dependent Claim
18 words
A process according to claim 6, wherein said image on said recording carrier is a colored toner image.
Claim 12
Dependent Claim
17 words
A process according to claim 1 or 2, wherein said card core material comprises a roughened film.
Claim 13
Dependent Claim
49 words
A process according to claim 1 or 2, wherein said card core material comprises several layers, at least one of said layers including security markings, and each of at least two layers include a photograph reproduced thereon, said photographs being in a staggered arrangement with respect to one another.
