    Abstract: A printing assistance apparatus for a media width printhead is provided. The printhead has rows of fluid ejection nozzles extending along the media width, The apparatus has an elongate platen having a surface for supporting media across the media width as the media travels past the printhead along a media travel direction, the platen having an elongate slot along the media width, a wick element positioned within the slot for wicking fluid ejected by the nozzles from the supporting surface, and an alignment mechanism for aligning the platen with the printhead so that the opposed longitudinal edges of the slot are respectively positioned upstream and downstream of the media travel direction with respect to a centerline along the length the nozzle rows with the upstream edge being closer to the centerline than the downstream edge such that the wick element has a smaller upstream surface area.

    Abstract: A device for sorting particles. The device may include a channel structure that defines a channel having an inlet and first and second outlets. The device also may include first and second transport mechanisms. The first transport mechanism may be configured to create a particle stream of first particles and one or more second particles. Each particle may move along the channel from the inlet toward the first outlet and may be disposed in a fluid supported by the channel structure. The second transport mechanism may be configured to be pulse-activated to selectively move at least one of the second particles from the particle stream and toward the second outlet.

    Abstract: An ink set providing reduced differential lightfade and graininess. The ink set comprises at least one dark inkjet ink and at least one light inkjet ink. The dark inkjet ink comprises at least one pigment having a high chromaticity and a low lightfastness and the light inkjet ink comprises at least one less chromatic pigment having a high lightfastness. The pigment in the dark inkjet ink is dissimilar from the pigment in the light inkjet ink in at least one of a crystal form, particle size, chromophore, and chemical dispersant. A method of reducing differential lightfade and graininess in a printed image is also disclosed.

    Abstract: An inkjet ink that provides improved print quality on diverse types of print media. The inkjet ink includes a first pigment dispersion and a second pigment dispersion in which the pigments are formulated to segregate when deposited on a glossy print medium. Each of the pigments in the first and second pigment dispersions may have at least one of a different particle size, a different particle morphology, and a different manner of dispersion. An inkjet ink that provides improved print quality on a print medium having chemically and physically distinct domains is also disclosed.
