Abstract
A method for marking cold (e.g., about room temperature to 800.degree. F.) substrate (e.g., glass, ceramic, metal) commences by creating a tape of a carrier backing bearing a laser ablatable, non-tacky coating with optional barrier and release coatings between the carrier backing and the coating. The coating is laser ablated to form one or more of alphanumeric characters or graphics on the carrier backing. The ablated coating on the carrier backing is heated to form a tacky film of the coating on the carrier backing. The tacky film is roller transferred from the carrier backing onto a pliable transfer pad. Finally, the tacky film is roller transferred from the pliable transfer pad onto the cold substrate for its marking.
