Abstract: An article comprising an electrically-conductive metal-containing pattern is provided by: A-1) providing a pattern of a catalytic ink on a surface of a first substrate; A-2) curing the pattern of the catalytic ink sufficient to form a cured catalytic ink pattern; A-3) electrolessly plating a metal on the cured catalytic ink pattern to form a metallic pattern on the cured catalytic ink pattern; B) applying a first darkening agent directly to a first surface of the metallic pattern to form a first darkened surface; C) transferring the metallic pattern to a second substrate so that the first darkened surface is in direct contact with the surface of the second substrate, leaving an undarkened second surface of the metallic pattern exposed to view; and D) applying a second darkening agent directly to the undarkened second surface of the metallic pattern, to form a second darkened surface of the metallic pattern.

Abstract: A negative-working lithographic printing plate precursor has a negative-working infrared radiation-sensitive image-recording layer that has a) two or more free radically polymerizable components; b) an initiator composition capable of generating free radicals; and c) one or more infrared radiation absorbing cyanine dyes. The a) two or more free radically polymerizable components comprise a combination of a urethane (meth)acrylate and a polyester (meth)acrylate, which together, comprise 75-100 weight % of all free radically polymerizable components. The weight ratio of the urethane (meth)acrylates to the polyester (meth)acrylates is from 90:10 to and including 35:65. The urethane (meth)acrylates comprise one or more urethane linkages and at least 4 acrylate or methacrylate ester groups. Each of the one or more polyester (meth)acrylates is free of a urethane linkage and is represented following structure (I). These precursors are less sensitive to ambient ozone and can be infrared radiation imaged and developed on-press during lithographic printing.

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 plurality of different feature shapes positioned in a pattern of 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: An aqueous colored pigment-based ink that is capable of fluorescence, has a pigment colorant in an amount of 1-7 weight %; a non-polymeric fluorophore that when excited by fluorescence-exciting radiation having a peak of at least 200 nm and up to and including 400 nm, exhibits an emission peak of at least 400 nm and up to and including 750 nm, and which non-polymeric fluorophore is present in an amount of 0.1-2 weight %; and an aqueous medium comprising water. This aqueous colored pigment-based ink can be included in an ink set that also includes one or more aqueous colored pigment-based inks that are non-fluorescent. All of these inks can be inkjet printed on non-UV fluorescent substrates to provide images that can be detected when excited as noted above, which images can be provided on documents, lottery tickets, and other security papers.

Abstract: A foamed, opacifying element has a substrate with opposing planar surfaces and a foamed opacifying layer disposed on one opposing surface. The foamed opacifying layer contains (a) 0.1-80 weight % of nonporous polymeric particles; (b′) 10-80 weight % of a matrix material derived from a (b) binder material having a glass transition temperature of less than 40° C.; (c) 0.0001-50 weight % of certain additives; (d) less than 5 weight % of water; and (e) at least 0.002 weight % of an opacifying colorant different from all of the (c) additives. Foamable and foamed aqueous compositions can be used to provide these foamed, opacifying elements for use as light-blocking window shades, curtains, or other materials. These light-blocking articles can also have a printable outer surface that accepts ink for making printed images that are not observable from the opposite surface.

Abstract: IR-sensitive lithographic printing plate precursors provide a stable printout using a unique IR-sensitive image-recording layer. The IR radiation-sensitive layer includes: component (1) a free radical initiator composition; component (2) a free radically polymerizable composition; and component (3) a color-changing compound of Structure (I) having an indene structure in the conjugated chain between the aromatic terminal groups. A specific group, such as a halo group, is directly or indirectly attached to this indene structure. The infrared radiation-sensitive image-recording composition and layer also contains one or more borate ions. After infrared imaging, these precursors exhibit desirable fresh or initial printout and printout after dark storage. The precursors can be developed on-press.

Abstract: A method for correcting in-track position errors in a digital printing system includes determining a non-linear in-track position correction function responsive to measured in-track position errors, wherein the in-track position corrections are quantized to integer in-track position corrections. A representation of the in-track position correction function is stored in a digital memory, wherein the representation of the in-track position correction function includes the cross-track positions and transition direction of transitions in the in-track position correction function. Digital image data for a digital image to be printed is received, and corrected image lines are determined by resampling the digital image data responsive to the stored representation of the in-track position correction function. The corrected image lines are modified to provide anti-aliasing pixels at cross-track positions adjacent to transitions in the in-track position correction function.

Abstract: Laminate precursors are prepared by applying an aqueous foamed opacifying composition to a non-woven fabric, drying, optionally applying an anti-blocking material to the dried aqueous foamed opacifying composition, and densifying the dry foamed opacifying layer so that it will have a thickness that is at least 20% less than its thickness before densifying. Each laminate precursor is rolled up for immediate or later use to make laminate decorative articles when the unrolled laminate precursor is laminated with back side of a decorative fabric. The applied aqueous foamed opacifying composition has 35%-70% solids and a foam density of 0.1-0.5 g/cm3. It is composed of (a) porous particles, (b) a binder material, (c) two or more additives comprising at least one foaming surfactant and at least one foam stabilizer, (d) an aqueous medium, and (e) an opacifying colorant that absorbs electromagnetic radiation having a wavelength of 380-800 nm.

Abstract: A printhead in a digital printing includes an array of light sources for exposing a photosensitive medium moving past the printhead. Artifacts are reduced in a high-speed print mode by defining first and a second power level control values that differ by at least 20%. The light sources used to print odd-numbered image pixels are activated responsive to the first power level control value and the light sources used to print even-numbered image pixels are activated responsive to the second power level control value.
