The RTM marker is particularly suitable for printing production dates, expiration, lot number, weights and other similar texts on 8 to 10 lines of print.

The printing process takes place by hot ink released from thermoplastic hot ink rollers under slight pressure and during rotation on metallic types and fixed clichés. While rotating the ink loaded onto types produces the printing on the packaging film.

The kind of text font can be chosen from among some available and the height of the usual printed character is 3 mm to 10 mm or customized.

The RTM printing group consists of the RTM print head, including its own support, encoder, TDE electronic controller and metal types or cliches in the required quantity.

Modified versions (eg RTM40 °) are designed to meet specific customer needs.
