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.

Embossing using clear ink

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.

Imaging apparatus and methods for homogenizing ink

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.

Preconditioning media for embossing

A printing mechanism comprises a printhead that defines a printzone, and a tray adapted to support at least one sheet of print media. The tray is adapted to move through the printzone during printing by the printhead on the sheet.
