Gravure Printing

Gravure printing is a widely-used high quality, fast speed printing technique e.g. for magazine printing. It utilizes engraved cells on a printing plate or cylinder to transfer the ink to the substrate.

Empa's gravure cylinder

Empa's gravure cylinder is specially designed for printing very fine details and structures required for printed electronics (down to 9 Micrometer). It is also has the capability to print very thin layers of functional inks.
1 Printed Ag grids for use as transparent electrodes ( 2 Printed dot structure of polymeric material on PET foil. 3 Printed Ag current collector on CIGS solar cells. 4 Flexible and transparent electrode: A gravure printed conductive Silver grid and busbar on PET foil.
Circuit with a glue-bonded SMD-LED to prove conductivity of the gravure printed nano-silver ink.


The CCC is also home to a small lab gravure printer for ink testing on flexible A5-sized substrates. Here, gravure plates are used, which allow a very fast workflow. A gravure plate with various cell parameters (e.g. depth, size) as well as a gravure plate with very fine structures are available.
