Abstract:
Disclosed herein are systems methods for using ink comprising organometallics in a flexographic printing process using engraved anilox rolls to transfer ink to an impression roll that prints a pattern on a substrate. A banded anilox roll with more than one geometry and/or volume of cells may be used in these production systems and methods. The pattern printed may comprise a plurality of lines which are each from 1 micrometer - 25 micrometers wide and may be part of an electronics application such as a touch screen sensor or an RF antenna that requires microscopic conductive patterns such as touch screen displays or antennas.
Abstract:
Touch sensor circuits are used in touch screens for displays and graphical interfaces and may be, for example, resistive or capacitive touch sensor circuits. The touch sensor circuits may be manufactured using at least one catalytically active printable ink that may contain a plurality of radiation-curable binders, a plurality of coated electrically conductive nanoparticles, a solvent, and may contain photo-initiators. The plurality of nanoparticles are coated by one of surfactants, polymers, or carbon. The ink is formulated to be used in a printing process such as a flexographic printing process or inkjet process to print complicated geometries for microscopic patterns, particularly high resolution conductive patterns.
Abstract:
The disclosure disclosed herein is a method for altering the optical properties of high resolution printed conducting patterns by initiating a chemical reaction to a passivating layer on the patterns with optical properties differing from the untreated material. The electrical properties are maintained after this reacted, passivating, layer is formed.

Abstract:
A method for making a light guide includes transferring ink onto a master tool having a three-dimensional feature pattern formed thereon and then transferring ink from the master tool to a transparent light guide. The method also includes curing the ink on the light guide. Alternatively, the ink may be printed onto a substrate (e.g., a film) and then laminated to the light guide.

Abstract:
The present disclosure provides a method for making anti-glare (AG) coating by using a flexographic printing process, wherein the printing ink that is used to achieve the AG effects may be prepared to contain organic or inorganic particles with irregular shapes that provides scattering centers to redirect the incident light. The printing process may include a series of steps that involve an ink pan, an anilox, a master roller, and a flexoplate mounted on the master roller. The AG coating may be cured to form an anti-glare coating with low haze and gloss.
