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.
- Engraved elements on gravure cylinder.
- Mass-printing technique
- High variety of low viscosity inks can be used (UV, solvent, waterbased etc.)
- Web speed ≤ 100 m/min
- Resolution ≤ 355 dpi, ≥ 10μm
- Film thickness: 0.02 – 8 μm
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.
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.
