Hot Foil Coding for Batch Numbers and Use By Dates
http://www.label-on.com
Put simply the labels on the labelling machine pass through a gap between a heated type set holder and a backing pad. Just in front of the heated type set is an ink ribbon a little bit like what you might see in old printers or typewriters. The heated type set is placed on the end of a short stroke pneumatic cylinder. At the end of a label feed the controls of the LabelOn™ give a signal to the pneumatic cylinder of the hot foil coder to stamp onto the Label.
