  • Patent number: 6891555
    Abstract: In a card-making method and system, an authentication card is made from a raw card having a readable and writable information-storing portion formed therein, by forming the image on the front surface and/or back surface of the raw card and writing individual authentication information in the information-storing portion. Processing information of the raw card is written in the information-storing portion. The image is formed based on the processing information read from the information-storing portion. Individual authentication information of the authentication card is written in the information-storing portion after forming the image. In a heat treatment mechanism for cards, heat treatment is applied to a card having an information-storing portion arranged in part of a surface of a card body of a card, by using a light source as a heating source, to thereby fix an image to the card.

  • Patent number: 6565204
    Abstract: There are provided an image-forming method which is capable of improving image quality of a transfer image, and a transfer sheet film therefor, as well as an image-forming apparatus. An image is printed on at least one transfer sheet film provided for use on at least one of front and back surfaces of a print medium, by using sublimable dye ink, thereby causing the sublimable dye ink to be held in the transfer sheet film. The at least one transfer sheet film and the print medium are overlaid to each other such that a printing surface of the transfer sheet film faces the at least one surface of the print medium. The image is transferred by heating the transfer sheet film and the print medium overlaid to each other while applying pressure thereto and thereby causing diffusion of the sublimable dye ink held in the transfer sheet film in the at least one surface of the print medium for color development. Then, the transfer sheet film is removed from the print medium having the image formed thereon.

  • Publication number: 20030007055
    Abstract: There is provided an image-forming apparatus and method which forcibly removes moisture of ink forming a printed image, thereby enhancing the quality of a transferred image formed by transferring the print image. A printer device prints an image on a transfer film, with a sublimable dye ink, by an ink jet printing method. A dryer device vaporizes moisture of the sublimable dye ink of a printed image formed on the transfer film. A thermal press carries out a thermal pressing process on the dried transfer film and the print medium overlaid with each other, to thereby diffuse and fix the sublimable dye ink held in the transfer film on a surface of the print medium.

  • Publication number: 20030007061
    Abstract: There is provided provide an image-forming apparatus that is capable of bringing a transfer film and a print medium into intimate contact without any gap therebetween, to thereby enhancing the quality of an image transferred from the film to the print medium. An image-forming apparatus uses a print medium, and a transfer film formed of a water-soluble resin material and having a smooth printing surface, to form a transferred image on the print medium. An image is printed on the printing surface of the transfer film, with sublimable dye ink. The printed transfer film and the print medium are overlaid such that the printing surface of the transfer film faces a transfer surface of the print medium. The printed transfer film and the print medium overlaid to each other are sandwiched and a thermal pressing process is performed on the printed transfer film and the print medium to cause the image printed on the transfer film to be diffused and fixed on the transfer surface.

  • Patent number: 6422692
    Abstract: There is provided an ink cartridge that is capable of supplying a pigment-based ink and at the same time suppressing the mixing of a sedimentary ink into the supplied pigment-based ink, or suppressing the generation of the sedimentary ink even when left unused, or removing the sedimentary ink by initial delivery of the ink after the cartridge is left unused, thereby reducing unevenness of printing. An ink reservoir holds an ink absorbent material therein for storage of the pigment-based ink. An ink delivery block is formed at a lower portion of the ink reservoir, and has a communication passage formed therethrough such that it extends from an outside of the ink reservoir up to an inner opening of the communication passage opening into an inside of the ink reservoir, for communication between the outside and the inside of the ink reservoir. The sedimentary ink is suppressed from flowing to the inner opening.

  • Patent number: 6412933
    Abstract: There is provided an ink cartridge device which permits a delivery port-sealing film thereof to be positively peeled off and prevents ink from scattering out of the device during an operation for peeling off the delivery port-sealing film. An ink cartridge has an ink delivery port for supplying ink to the printer therefrom, and a rim of the ink delivery port. A container box contains the ink cartridge and has a box body and a lid for closing the box body. The box body is formed with a slit. A delivery port-sealing film has a sealing portion removably welded to the rim of the ink delivery port, for sealing the ink delivery port, and an unsealing operation portion continuous with the sealing portion and extending in a direction of making a U-turn with respect to the sealing portion to extend out of the container box through the slit of the box body.
