Matthews’ 8000-Series printheads operate on a high-pressure ink system, which effectively blows out any dust particles that may settle in the orifice. This also adds to the throw distance, which allows for some variation in the presentation of the bags to the printheads. We offer porous and non-porous inks, including FDA-approved inks, to mark paper or plastic bags with date, time, and lot info in a wide selection of colors. A simple operator interface makes message selection a breeze. You can also transmit messages from a PC, minimizing your coding errors.
