  • Patent number: 7300146
    Abstract: A printing device including a plurality of cartridges, at least one cartridge including a visible ink and at least one cartridge including a clear ink; a print portion; and an accessory module in connection with the print portion; wherein the clear ink of at least one cartridge has a longer drying time than the visible ink of at least one cartridge.
    Type: Grant

  • Patent number: 7140724
    Abstract: Imaging apparatus and methods of homogenizing ink are described. In one implementation an imaging apparatus includes an ink supply to provide ink to be used in printing, and a printhead to apply the ink during printing. A conduit system couples the ink supply and the printhead in fluid flowing relation. A pump is operably coupled to the conduit system. In operation, the pump causes the ink to circulate between the ink supply and the printhead. A timing device measures an idle-time since the pump was last in operation. A controller receives the idle-time measurement from the timing device, and actuates the pump when a selected idle-time is reached. In another implementation, a method for homogenizing ink includes providing a pump, then automatically actuating the pump to homogenize ink within an ink delivery system each time the ink delivery system has been resting for a selected idle-time.

  • Patent number: 7048367
    Abstract: A preconditioning process is disclosed that provides applying a first fluid to a media; applying a second fluid including an ink to the media, at least a portion of which is applied over the first fluid, wherein a sufficient amount of the first fluid extends a drying time of the second fluid; and applying an embossing powder to the media before the second fluid has substantially dried.
