Thermal transfer printing is a digital printing process in which material is applied to paper or other packaging substrate by melting a coating (ink) of ribbon so that it stays glued to the material on which the print is applied. It contrasts with direct thermal printing where no ribbon is present in the process.
In simpler terms- just look at the product variable information code (price, expiry date, lot code, etc.) that is printed, generally in black, on a snack food bag in the local grocery store – if the characters printed are solid the code has been printed via thermal transfer.
Thermal Transfer printers and overprinters can be integrated on to many flat package feed systems including flow wrappers, horizontal or vertical form-fill-seal machines, labelers, pick & place or friction feed systems as examples.
