A liquid ejection head includes a print element substrate having an ejection port surface in which a plurality of ejection ports are arranged and a temperature control unit that controls a temperature of the ejection port surface. The print element substrate ejects a liquid from the plurality of ejection ports onto a medium moved by the liquid ejection head relatively to the liquid ejection head. The ejection port surface includes a region on a downstream side of the ejection port surface in a direction in which the medium relatively moves when the medium is viewed from the liquid ejection head, and includes a region on an upstream side of the ejection port surface in the relative moving direction. The temperature control unit control the temperature of the ejection port surface so that a temperature of the downstream side region becomes higher than a temperature of the upstream side region.

Method and apparatus for digital printing

A method of indirect digital printing is disclosed herein. The method employs (i) first (e.g. transparent) and second aqueous ink components (comprising colorant particles) and (ii) a target surface (e.g. hydrophobic) of an intermediate transfer member (ITM). A quantity of first ink component is deposited (e.g. by ink-jetting) onto the target surface and partially dried to produce a partially-dried layer thereon. Droplets of the second ink component are deposited onto the partially-dried layer of first ink component to form a wet, colored ink-image. Upon deposition of the droplets of the second ink component, the colorant particles from the second component penetrate into the partially-dried layer of the first ink component. The wet, colored image is dried into a tacky ink-image-bearing residue film which is transferred to the substrate. Physical and/or chemical properties of the first and second ink components as provided by various embodiments are disclosed herein.

11703778 · 2023-07-18 · ·

An apparatus and methods of decorating a metallic container are provided. More specifically, the present invention relates to apparatus and methods used to provide a decoration or indicia on a predetermined portion of an outer surface of a metallic container body. The decorator includes at least one digital print unit, a transfer blanket, and a support element. The digital print unit transfers a decorating material to the transfer blanket to form a decoration on the transfer blanket. The support element then moves a metallic container into contact with the transfer blanket. In this manner, the decorating material is transferred to an exterior surface portion of the metallic container to decorate the metallic container. In one embodiment, the digital print unit is an electrophotographic system which transfers a toner material to the transfer blanket. In another embodiment, the digital print unit includes an inkjet print head which transfers an ink to the transfer blanket. Optionally, the decorator may include two or more support elements.

IMAGE FORMATION WITH ULTRASONIC LIQUID REMOVAL

An image formation device includes a support, a fluid ejection device, and a first porous element. The support is to support movement of a substrate along a travel path, while the fluid ejection device is located along the travel path to deposit droplets of colorants within a liquid carrier onto the substrate to at least partially form an image on the substrate. A first porous element is located downstream from the fluid ejection device to be in contact against the substrate to remove, via capillary flow, at least a portion of the liquid carrier from the substrate. An ultrasonic element is in contact against the first porous element, at a location separated from a location at which the first porous element engages the substrate, to drive the removed liquid carrier out of the first porous element.
