A non-aqueous composition contains dispersed carbon-coated metal particles in an organic diluent in an amount of at least 10 weight %. The dispersed carbon-coated metal particles have a median diameter equal to or less than 0.6 &#x3bc;m, and are dispersed using a particle dispersing agent that has a weight average molecular weight (M) of at least 2,000 and up to and including 100,000 and comprises nitrogen-containing units. The median diameter of the dispersed particles is determined using a dynamic light scattering method. Moreover, when the non-aqueous composition contains up to and including 25 weight % of the dispersed carbon-coated metal particles, it exhibits no visual settling when subjected to a settling test of at least 24 hours at 20&#xb0; C. Such non-aqueous compositions can include photocurable components and are useful to prepare photocurable and photocured electrically-conductive patterns and layers in various articles, including touch screen devices having touch screen displays.

A flexographic printing system uses a flexographic printing plate to produce printed patterns on a substrate. An ink recirculation system is used to reduce variability in system performance resulting from ink viscosity changes. A recirculation pump moves ink through an ink recirculation line connected to an ink reservoir. A metering pump adds a controlled flow rate of solvent from a solvent replenishment chamber into the ink recirculation line, thereby providing replenished ink which is returned to the ink reservoir. A control system is used to control the flow rate of solvent provided by the metering pump responsive to feature characteristics determined by analyzing a captured image of the printed pattern.

Flexographic printing system providing controlled feature characteristics

A method for controlling feature characteristics in a flexographic printing system that forms a printed pattern on a substrate by applying ink from an ink reservoir using a flexographic printing plate mounted on a plate cylinder. An imaging system is used to capture an image of the pattern printed on the substrate, and the captured image is analyzed to determine a feature characteristic of one or more features of the printed pattern. A control system automatically controls an amount of solvent used to replenish the ink in the ink reservoir responsive to the determined feature characteristic.

Controlling line widths in flexographic printing

A flexographic printing system uses a flexographic printing plate to produce printed patterns on a substrate. An ink recirculation system is used to reduce variability in system performance resulting from ink viscosity changes. A recirculation pump moves ink through an ink recirculation line connected to an ink reservoir. A metering pump adds a controlled flow rate of solvent from a solvent replenishment chamber into the ink recirculation line, thereby providing replenished ink. The replenished ink is returned to the ink reservoir through a distribution tube that includes a plurality of supply ports at a plurality of spaced apart locations across a width of the ink reservoir. A control system is used to control the flow rate of solvent provided by the metering pump.
