Abstract: A printhead includes a substrate having an enclosure that includes an aperture through which liquid drops and gas flow are emitted. An array of liquid drop ejectors is included in the enclosure, which eject the liquid drops emitted through the aperture in response to image data. An array of gas flow ejectors is included in the enclosure, which emit the gas flow through the aperture.

Abstract: Preparing a flexographic member (60) includes providing a digital image and calculating a relief image based on the digital image. At least one stress-sensitive boundary region (11) adjacent to at least one image feature is identified and the relief image is created on the flexographic member. The depth (18) of at least a portion of a floor region (10) adjacent the at least one image feature is increased to provide a modified floor region.

Abstract: A method is used to make a laser-ablatable element for direct laser engraving that has a laser-ablatable, relief-forming layer that has a relief-image forming surface and a bottom surface. The relief-forming layer can be prepared by applying multiple formulations. Each formulation comprises a coating solvent, a laser-ablatable polymeric binder, and an infrared radiation absorbing compound. The infrared radiation absorbing compound concentration in the resulting sub-layers is different in each adjacent pair of sub-layers so that the concentration is always greater in each pair sub-layer that is closer to the substrate, and the concentration is progressively greater in the sub-layers as they are closer to the substrate after the coating solvent is removed, wherein the multiple sub-layers provide a relief-forming layer so that the sub-layer farthest from the substrate provides a relief-image forming surface.

Abstract: A laser-ablatable element for direct laser engraving has a laser-ablatable, relief-forming layer that has a relief-image forming surface and a bottom surface. This relief-forming layer includes a laser-ablatable polymeric binder and an infrared radiation absorbing compound that is present at a concentration profile such that its concentration is greater near the bottom surface than the image-forming surface. This arrangement of the infrared radiation absorbing compound provides improved ablation efficiency, particularly when laser exposure is carried out adiabatically.

Abstract: An inkjet printer system and method for recording an image in a single pass print mode includes a printhead having a plurality of nozzles that are selectively operable for depositing drops of liquid ink or other liquid used in forming of an image in a single pass print mode upon a surface of a receiver medium with a printing resolution R, a dot size Di of the dots resulting from impact of the drops with the receiver medium being in the range of 0.5/R<Di<1/R and a final dot size D after spreading on the surface being in the range of 2½/R<D<2.0/R. The receiver medium has a surface for receiving the drops and a region of the medium proximate the surface has an influence upon drop spreading and the region has a porosity in the range of 0.2 to 0.8 and sufficient to provide a media drop spread factor Sm wherein Sm=D/Di with 2½<Sm<2×2½.

Abstract: A method for increasing the diameter of an ink jet ink dot resulting from the application of an ink jet ink drop applied to the surface of an inkjet recording medium having a support having thereon an image-receiving layer and an overcoat layer, the ink penetration rate of the overcoat layer being faster than the ink penetration rate of the image-receiving layer; having the steps of: a) applying the overcoat layer on top of the image-receiving layer at a thickness less than the maximum thickness, the maximum thickness being that thickness whereby an ink jet ink drop applied to the surface of the overcoat layer will not substantially penetrate the surface of the image-receiving layer; and b) applying the ink jet ink drop on the surface of the overcoat layer whereby the diameter of the ink jet ink dot is increased relative to that which would have been obtained if the overcoat layer had been coated at a thickness of at least the maximum thickness.

Abstract: Disclosed is an imaging element comprising a single layer containing a random distribution of a colored bead population of one or more colors coated above one or more layers comprising light sensitive silver halide emulsion grains, wherein the population comprises beads of at least one color in which at least 25% (based on projected area) of the beads of that color have an ECD less than 2 times the ECD of the silver halide grains in said one emulsion layer or in the fastest emulsion layer in the case of more than one emulsion layer
