A splice tape for a thermally imaging web. A polymer tape layer, which is thin and strong, has an adhesive layer on its lower side and a thermally imaging composition on its upper side. The thermally imaging composition is similar to the thermal imaging layer on the web. When two ends of a web are joined, the splice tape is placed thereon to join the two ends. The splice tape may be printed at the same time as the web. The thinness of the splice allows the printing to be consistent at the splice, minimizing blank areas.
