At the FachPack 2018 trade fair, Paul Leibinger GmbH & Co. KG showed the JET One, a new industrial inkjet printer for marking and coding e. g. food packaging. The ­entry-level model is suitable for ­marking and coding packaging with fixed and variable data such as best-before date, LOT and batch number as well as graphics. The marking takes place without contact with flying drops of ink, making it suitable for convex and concave, rough and smooth, flat and relief-moulded product surfaces.

It is possible to print country and industry-specific fonts with a character height of 1.5 to 8 mm in up to two lines. Since the ink dries in less than a second, the CIJ printer can handle production speeds of up to 268 m/min. Ink consumption is minimal: the JET One prints up to 120 million characters with only 1 l of ink.

The problem many users face with CIJ printers is that the ink dries during production breaks. This causes time-consuming cleaning, which delays production restarts. In the worst-case scenario, the printing is diffuse with illegible type and expensive reworking required during production. The solution in the case of the JET One printer is its unique Sealtronic feature, a nozzle sealing system that keeps the ink fresh during production breaks. Leibinger has designed the user interface so that intuitive operation is possible without a long training period.
