Gravure Printing

Gravure printing is a widely-used high quality 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.

Labratester
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 garvure plate with various cell parameters (e.g. depth, size) as well as a gravure plate with very fine structures are available.
