Abstract: A method of coating a label, such as a ceramic ink label, on a container includes the use of a coating material that will serve as a barrier to prevent migration or permeation of the ink and the components of the ink from the label through the coating barrier. The coating will prevent the label from wearing, scuffing, or rubbing off as well as improve the label's resistance to repeated handling. The method also includes application of a coating that may be washed off prior to refilling and reusing the container, without affecting the underlying label or ink components of the label. The coating may also make the label more aesthetically appealing to a consumer.
