Abstract: A method and apparatus for producing identification (ID) cards using a photosensitive imaging system employing microcapsules is described. In accordance with one aspect of the invention, ID cards are produced by translating an image containing identifying indicia into a latent image on an appropriate photosensitive donor sheet, pressure developing the latent image, forming a full color print of the image on a developer sheet, laminating an ID card substrate in registration with the image to the developer sheet and die cutting the laminated article to produce an ID card. Self-contained imaging systems can also be used to produce identification cards. The image preferably includes unique information useful in identifying the card holder such as a photograph, fingerprint, signature, description, name, etc. The identifying indicia may be combined with non-variable information including background printing, card issuer data, logos, security features, etc.

Abstract: A new digital printer media which allows to create images on both sides of a single sheet is proposed. The media is printed in a new Cycolor printer which utilizes two LED printer heads and one developer head/device. The film consists of the top and the bottom layers of capsules/developer coats on clear polyester (top and bottom) with the white polyester with adhesive on both sides as the separator. The color producing capsules/developer mixture is coated on clear polyester. The coated film is then laminated with white polyester containing adhesive on both sides. The top side of the white polyester remains protected by the removable liner. Thus created film is then used to laminate another layer of capsule/developer coated clear polyester. The double sided film is thus created. Following exposure from both sides will occur independently by a set of two LED heads. Developing pressure can be applied from one side. Two images can be formed at the same time on both sides of a single sheet.
