    Abstract: A method for fabricating a flexographic printing plate for printing image patterns including one or more uniform image regions includes defining a repeating tile having a pattern of feature shapes positioned at pseudo-random feature locations. A plate formation pattern corresponding to the image pattern is determined wherein the repeating tile is applied in a tiled arrangement to the uniform image regions. The plate formation pattern is used to form a flexographic printing plate, wherein regions of the flexographic printing plate corresponding to the uniform image regions of the image pattern include a pattern of raised features in positions corresponding to the feature positions in the repeating tile.

    Abstract: A composite article has a transparent polymeric film and an electrically-conductive, metal-containing pattern disposed on a surface of the transparent polymeric film. The electrically-conductive, metal-containing pattern has, in order outwardly from a surface of the transparent polymeric film: a metallic pattern having a first surface facing the transparent polymeric film and an opposing second surface; and a pattern of a catalytic ink disposed over at least a portion of the second surface of the metallic pattern. The transparent polymeric film with the electrically-conductive, metal-containing pattern disposed thereon is sandwiched between two panes of transparent rigid substrates and serves as a transparent laminating film to form the composite article.

    Abstract: A printed electrical device is formed using a flexographic printing system. A flexographic printing plate having a pattern of raised features includes an active region having a plurality of parallel traces separated by a trace spacing of between 5-40 microns that are used to form active micro-traces that provide an electrical function, and an inactive region adjacent to the active region having one or more protective features that are used to form electrically-inactive features. The protective features are separated from an outermost trace of the plurality of traces by a gap distance of between 60% and 250% of the trace spacing. The flexographic printing plate is used to transfer ink from an anilox roller to a substrate to provide a printed pattern corresponding to the pattern of raised features on the flexographic printing plate.

    Abstract: An article has an electrically-conductive metal-containing pattern and is prepared by: A) providing a metallic pattern on a first substrate; B) applying a darkening agent to the metallic pattern to form a first darkened surface; C) transferring the metallic pattern to a second substrate, leaving an undarkened second surface of the metallic pattern exposed to view; and D) applying a second darkening agent to the undarkened second surface. The first darkened surface formed in B) can have an L* value that is reduced by at least 1 unit compared to an L* value of the metallic pattern provided in A) before application of the darkening agent. Moreover, the second darkened surface formed in D) can have an L* value that is reduced by at least 1 unit compared to an L* value of the undarkened surface of the transferred metallic pattern provided in C).

    Abstract: A flexographic printing system prints image patterns including one or more uniform image regions on a substrate. A flexographic printing plate includes a pattern of raised features for transferring ink to the substrate in accordance with the image pattern. An anilox roller having a plurality of anilox cells is configured to transfer ink to the flexographic printing plate. Uniform image regions of the flexographic printing plate corresponding to the uniform image regions of the image pattern include a pattern of raised feature shapes positioned in a pattern of pseudo-random feature locations. An average spacing between the raised feature shapes in the uniform image regions is less than an anilox cell size such that a plurality of the raised feature shapes receive ink from a single anilox cell of the anilox roller.

    Abstract: A transparent article is prepared with a transparent polymeric film and an electrically-conductive, metal-containing pattern disposed over a surface of the transparent polymeric film. Such pattern has, in order outwardly from a surface of the transparent polymeric film: a metallic pattern having a first surface facing the transparent polymeric film and an opposing second surface; and a pattern of a catalytic ink disposed over at least a portion of the opposing second surface. Such articles can be prepared by A-1) providing a pattern of a catalytic ink on the surface of the first substrate; A-2) curing the catalytic ink pattern sufficient to form a cured catalytic ink pattern; A-3) electrolessly plating a metal onto the cured catalytic ink pattern to form the metallic pattern on the surface of the first substrate, and B′) transferring the metallic pattern to a surface of a second substrate that is a transparent laminating film.

    Abstract: An article is provided to have a transparent substrate; and an electrically-conductive, metal-containing pattern disposed on a surface the transparent substrate. The electrically-conductive, metal-containing pattern has, in order outwardly from a surface of the transparent substrate: a first darkening agent; a metallic pattern; and a second darkening agent. The first darkening agent substantially conforms to a first surface of the metallic pattern, forming a first darkened surface on the metallic pattern. In addition, the second darkening agent is disposed over at least a portion of a second surface of the metallic pattern, forming a second darkened surface on the metallic pattern.
