Visualization and Simulation of the Transfer Process of IndexMatched Silica Microparticle Inks for Gravure Printing

A combined experimental and computational study of the transfer of transparent index-matched silica-particle inks between two flat plates is presented for gravure printing applications. The influence of printing speed and initial ink droplet size on the ability to accurately transfer ink during the printing process is explored systematically. Smooth interface volume of fluid simulations show th...

Wettability Contrast Gravure Printing.

Silicon gravure patterns are engineered to have cells that are wettable and lands that are not wettable by aqueous inks. This strategy allows excess ink on the lands to be removed without using a doctor blade. Using an aqueous silica ink, continuous lines as narrow as 1.2 μm with 1.5 μm space are gravure printed.

Oxygen indicators and intelligent inks for packaging food.

The detection of oxygen using optical sensors is of increasing interest, especially in modified atmosphere food packaging (MAP), in which the package, usually containing food, is flushed with a gas, such as carbon dioxide or nitrogen. This tutorial review examines the ideal properties of an oxygen optical sensor for MAP and compares them with those developed to date, including the most recent a...

Major Trends in Gravure Printed Electronics

Printing has become a mature industry, forcing printers to create new applications for their manufacturing process. One such application is printed electronics. The gravure printing process allows for incredible speed and exceptional quality for traditional graphic printing. Theoretically, this would be an ideal method for the commercial production of printed electronics. This study analyzes gr...
