Gravure Ink

Printed and flexible biosensor for antioxidants using interdigitated ink-jetted electrodes and gravure-deposited active layer.

Printing techniques have been extensively used in the fabrication of organic electronic devices, such as light-emitting diodes and display backplanes. These techniques, in particular inkjet printing, are being employed for the localized dispensing of solutions containing biological molecules and cells, leading to the fabrication of bio-functional microarrays and biosensors. Here, we report the ...

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.

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...

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...
