Abstract
A method of printing on a release layer of linerless label material including the step of advancing linerless label material and a thermal transfer ribbon coated with ink through a thermal printer. The ribbon is moved over a heated transfer element of the printer. The heated transfer element is located on an edge or on a corner of an edge of the thermal printer. The ribbon is then heated to cause the ink to reach a molten or fluid state. The ink transfers in its molten or fluid state to the release layer of the linerless label material. Certain wax/resin and resin based thermal transfer ribbons and silicone release coatings have been found to be particularly effective for increasing the ink transfer and anchorage during corner edge and true edge printing on linerless label material.
